Why is potassium feldspar red? Is potassium shale potassium feldspar

Yes, the percentage composition of each ingredient is different.

Summary. Hello, potassium shale is potassium feldspar, and potassium shale is a type of potassium feldspar.

Hello, potassium shale is potassium feldspar, and potassium shale is a type of potassium feldspar.

Potassium feldspar can be used as raw materials for glass and ceramic industries, and is also used in other industries such as chemicals, abrasives, welding rods, etc.

The appearance is gray-green, fine-grained crystalline structure, massive structure, main minerals: microcline feldspar, quartz, fluorite, rare earth minerals, magnetite.

Potassium-bearing rocks are a unique concept of mineral resources in China's economic geology, which refers to various insoluble aluminosilicate rocks with potassium as a valuable component and high K2O content, such as potassium-bearing sandstone, shale, claystone, glauconite sandstone, alumite, mung bean rock, nepheline, potassium feldspar, etc. Potassium-bearing resources on the earth's crust can be basically divided into three categories: soluble potash ores.

Mainly chlorides, sulfates, and their double salts, with a small amount of nitrate. They are all soluble in water, such as potashite, carnallite, potash magnesia, and their mixtures. Seawater and salt lake brine.

Insoluble potassium-containing minerals and rocks. The first two categories can be directly used in agriculture to produce potassium fertilizer absorbed by crops, while insoluble potassium-containing minerals and potassium in rocks cannot be directly absorbed by crops, and must be physically or chemically treated to activate and convert potassium to make potassium fertilizer conducive to crop absorption, that is, to convert insoluble and ineffective potassium in rocks (or minerals) into soluble and effective potassium.

I hope mine is helpful to you.

Potassium feldspar Feldspar is an aluminosilicate mineral of alkali metals such as potassium, sodium, and calcium or alkaline earth metals, also called feldspar group minerals. Potassium feldspar[1] (kalsi3o8), also commonly known as orthoclase, is a monoclinic crystal system that is usually flesh-red, white or gray in color. Density 2 54-2 57g cm, specific gravity, hardness 6, its theoretical composition is SiO2, K2O.

It has the characteristics of low melting point (1150 20), long melting interval time and high melting viscosity, and is widely used in ceramic blanks, ceramic glazes, glass, electric porcelain, abrasive materials and other industrial sectors and potash fertilizers. In addition to orthoclase, there are two homogeneous polymorphic variants: feldspar and potassium microcline.

The former also belongs to the monoclinic crystal system, also commonly known as orthoclase; The latter belongs to the triclinic system. In addition to being used as raw materials for the glass industry (accounting for about 50-60% of the total amount), feldspar minerals account for 30% in the ceramic industry, and the rest are used in chemical industry and glass melting.

Agents, ceramic body ingredients, ceramic glazes, enamel raw materials, abrasives, glass fiber, welding rods and other industries. It is mainly used for glass, ceramics, and can also be used to prepare potash fertilizer, and better quality potassium feldspar is used to make TV imaging glass shells. Potassium feldspar: , of which K2O, Al2O3 16% or more, SiO2 70%, density 3, Mohs hardness of 6, monoclinic crystal system, color white, red, milky white, melting point 1290 c 。

Aluminosilicate minerals of sodium and potassium. It is the most common mineral in the earth's crust and can be found in igneous rocks, metamorphic rocks, and sedimentary rocks. Feldspar is the main mineral component of almost all igneous rocks and is of great significance for the classification of rocks.

Feldspar isomorphic substitution is well developed, and their chemical composition is often expressed by orxaby anz (x y z 100). OR, AB and AN represent kals3O8, naalsi3O8 and caal2Si2O83 components, respectively. Mainly with a certain two components, it can be divided into two quasi-homogeneous series:

alkaline feldspar series (i.e. OR-AB series); plagioclase series (i.e. ab-an series). The OR and AN components are only very limited miscible and do not form a series. The basic structural unit of feldspar is the tetrahedron, which consists of 4 oxygen atoms surrounding a silicon or aluminum atom.

Each of these tetrahedra shares an oxygen atom with the other tetrahedron, forming a kind of three-dimensional skeleton. Alkaline or alkaline earth metal cations with large radii are located in large voids within the skeleton with a coordination number of 8 (in monoclinic feldspar) or 9 (in triclinic feldspar). Feldspar crystals are mostly plate-like or plate-shaped columns that extend along a crystalline axis.

The phenomenon of double crystal is very common, and there are more than 20 kinds of double crystal laws. The common ones are albite law, Maniba, Bawinno's law, casbarr, and Xiao albite law bicrystal. They are found in triclinic crystals or monoclinic and triclinic crystals, respectively.

Feldspar is commonly milky white, but it is often dyed yellow, brown, light red, dark gray and other colors because it contains impurities, and some can also have beautiful color change or halo. There are two groups of complete cleavage, which are angled at 90° (monoclinic system) or nearly 90° (triclinic system). The specific gravity increases with the increase of the AN content in the component, and decreases with the increase of OR.

The Mohs hardness is 6. Feldspar rich in potassium or sodium is mainly used in the ceramic industry, glass industry and enamel industry; Feldspar containing rare elements such as rubidium and cesium can be used as mineral raw materials for extracting these elements; Beautifully colored feldspar can be used as a decorative stone and as a secondary gemstone.

1. Characteristics and chemical composition:

The hardness of feldspar fluctuates, the specific gravity fluctuates, it is brittle, has high compressive strength, and has strong chemical stability to acids. The color of potassium feldspar is mostly flesh red, but there are also gray and white-brown. Albite is white, gray and light yellow, and afeldspar is white or light gray.

Chemical Composition: SiO2, Al2O3, Fe2O3, K2O, Na2O, Others, Trace.

2. Uses: Manufacture of potash fertilizer, ceramics and enamel, glass raw materials, abrasive abrasives, etc.

Feldspar is an aluminosilicate mineral of alkali metals such as potassium, sodium, and calcium or alkaline earth metals, and potassium feldspar is an aluminosilicate mineral of potassium.

Potassium feldspar: (kalsi3o8) is also commonly known as orthoclase and belongs to the monoclinic crystal system. Its theoretical components are SiO2, K2O.

In the raw ore of the feldspar system, the content of potassium feldspar containing more than 5 K2O can be called potassium feldspar, and the most common potassium feldspar on the market has a potassium oxide content of about 10%.

Feldspar is an aluminosilicate mineral of alkali metals such as potassium, sodium, and calcium or alkaline earth metals, also known as feldspar minerals. Potassium feldspar (K2O·Al2O3·6SiO2) is also commonly referred to as orthoclase. The potassium feldspar series are mainly orthoclase, slightly oblique nachi feldspar, strip plum wheel feldspar and so on.
