What exactly does mica mean? What is mica?

Mica is a rock-forming mineral, and many of the characters in Inuyasha are named after gemstones, the Seven Treasures are the Seven Treasures of Buddhism, and coral and amber are among the Seven Treasures of the Buddha.

Mica is a kind of hydrated aluminosilicate with complex structure, which is commonly composed of granite with quartz and feldspar, or symbiotic in other mines, and is mainly pegmatite.

Mica is a general term for mica group of minerals, which is an aluminosilicate of potassium, aluminum, magnesium, iron, lithium and other metals, all of which are layered structures and monoclinic crystal systems. The crystals are pseudohexagonal or plate-like, occasionally columnar.

Introduction

In the industry, biotite mainly uses its insulation and heat resistance, as well as acid resistance, alkali resistance, compression resistance and peeling properties, as an insulating material for electrical equipment and electrical equipment.

Secondly, it is used in the manufacture of steam boilers, furnace windows and mechanical parts of smelting furnaces. Mica crushed and mica powder can be processed into mica paper, and can also be used instead of mica sheets to make a variety of low-cost, uniform thickness insulation materials.

Mica is a rock-forming mineral with hexagonal sheet-like crystals and is one of the main rock-forming minerals.

Mica is a class of hydrated aluminosilicates with complex structures with hexagonal flake crystals, which is one of the main minerals of rock-forming minerals. It is mainly used in industry and has the characteristics of insulation and high temperature resistance. Can be formed in a variety of geological conditions.

The color varies with the chemical composition, and mainly darkens with the increase of Fe content.

Features & Applications:

The natural nature of mica makes it the darling of the industry, and the wide availability is the most important, and now there is no need to worry about its quality and yield, the same industry standard, and the first is fundamentally transparent.

Mica and biotite are important for the manufacture of electrical equipment, and are good materials for making insulators, and they are also widely used. The mica we usually talk about is generally muscovite**, not biotite. There is a distinction in color, of course, there is still a difference in nature, and the rest is still to be noted.

Mica is a rock-forming mineral with a hexagonal sheet-like crystal shape, which is one of the main rock-forming minerals and has industrial and medicinal value.

1. Chemical composition.

Mica is a general term for hydrous aluminosilicate minerals containing lithium, sodium, potassium, magnesium, aluminum, zinc, iron, vanadium and other metal elements and with layered structure, and is a complex silicate.

2. Appearance characteristics.

Layered structure, monoclinic crystal system, the crystal is pseudohexagonal flake or plate-like, occasionally columnar, with glass luster, and the thin sheet is also elastic.

3. Subdivide the type.

Mica ore mainly includes biotite, phlogopite, muscovite, lepidolite, sericite, biotite, iron lepidolite, etc., and placer is a mixed mineral of mica and quartz.

Uses of mica:

The main use is Muscovite, followed by phlogopite. It is widely used in building materials industry, fire protection industry, fire extinguishing agent, welding electrode, plastic, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigment and other chemical industries.

Ultrafine mica powder is used as a functional filler for plastics, coatings, paints, rubber, etc., which can improve its mechanical strength, enhance toughness, adhesion, anti-aging and corrosion resistance.

In addition to having extremely high electrical insulation, acid and alkali corrosion resistance, elasticity, toughness and sliding properties, heat resistance and sound insulation, small thermal expansion coefficient and other properties, it also takes the lead in introducing the characteristics of smooth surface of the second sheet, large diameter-thickness ratio, regular shape and strong adhesion.

Mica is containing lithium, sodium, potassium, magnesium, aluminum, zinc, iron, vanadium, etcMetallic elementsand is a general term for hydrous aluminosilicate group minerals with layered structure.

Mica has hexagonal flake crystals and is one of the main minerals of rock-forming minerals. Mica has a large family with members such as muscovite, biotite, phlogopite, and lepidolite.

It is widely distributed in magmatic rocks and sedimentary rocks.

and metamorphic rocks.

Properties and uses of micaMica has high insulation, good chemical stability, and resistance to strong acids.

Strong alkali and stress resistance.

Therefore, it is an important raw material for the manufacture of electrical equipment, so it can also be used as an insulating material in hair dryers.

Mica also has the ability to birefringence, so it is also an optical instrument material for the manufacture of polarized light sheets.

For mica mining in the electrical industry, it is a mica block with an effective area of more than 4 square centimeters, and there are no cracks, perforations, and the non-mica minerals on the edges shall not exceed 3 mm. Muscovite is used more in industry, followed by phlogopite, which is widely used in building materials industry, fire protection industry, fire extinguishing agent, welding electrode, plastic, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigment and other chemical industries.

Mica is a type of rock-forming mineral with hexagonal sheet-like crystals and is one of the main minerals of rock-forming minerals. It is mainly used in industry and has the characteristics of insulation and high temperature resistance. Can be formed in a variety of geological conditions. <

1. Mica is an aluminosilicate mineral with a layered structure of potassium, aluminum, magnesium, iron, lithium, etc., with hexagonal flake crystals, which is one of the main minerals of rock-forming minerals. The mica crystal has a layered structure inside, so it is a layered crystal, mainly a hexagonal layered crystal. It has a large family, with members of muscovite, biotite, phlogopite, lepidolite, iron lepidolite, copper uranium mica, etc., which are widely distributed in magmatic rocks, sedimentary rocks and metamorphic rocks.

2. It is characterized by insulation, high temperature resistance, sericite is the most widely used in industry, widely used in coatings, paints, electrical insulation and other industries.

3. Mica minerals can be formed under various geological conditions. Biotite is one of the main rock-forming minerals of igneous rocks and is distributed in most of the rock base and epigenetic rocks. Muscovite is also a widely distributed rock-forming mineral found in igneous, sedimentary, and metamorphic rocks.

Phlogopite is mainly found in ultramafic rocks and magnesia marble.

Mica is a rock-forming mineral with hexagonal sheet-like crystals, which is one of the main rock-forming minerals and has industrial and medicinal value. Mica ore is widely found in Asia, Africa, and the Americas, but very little in Europe, and until the 19th century, mica's value in Europe was very high, and as colonizers mined mica in Africa and South America, it quickly declined.

Mica is a general term for mica group of minerals, which is an aluminosilicate of potassium, aluminum, magnesium, iron, lithium and other metals, with a layered structure, monoclinic crystal system, and the crystal is pseudohexagonal flake or plate-like, occasionally columnar, with glass luster, and the thin section is also elastic.

Mica can be refractive, and the refractive index increases with the increase of iron content in mica, for non-iron variants, it is colorless in the flakes, like some mica with high iron content, the color is very dark.

Industrial mica deposits are divided into two categories: muscovite deposits and phlogopite deposits, each of which can be divided into two subcategories, as well as crushed mica deposits. Although the distribution of mica minerals in China is uneven, although it is distributed in 20 provinces, municipalities and autonomous regions across the country, most of them are concentrated in Xinjiang, Sichuan and Inner Mongolia.

Mica ore mainly includes biotite, phlogopite, muscovite, lepidolite, sericite, biotite, iron lepidolite, etc., placer is a mixed mineral of mica and quartz, the most used in industry is muscovite and phlogopite, lepidolite is an important mineral raw material for refining lithium, and mica is characterized by insulation, high temperature resistance, so the most used in industry is sericite, which is widely used in coatings, paints, electrical insulation and other industries.
