What contains cadmium and what is cadmium?

1.Alloy: Cadmium as an alloy group can be formulated into many alloys, such as cadmium-containing hard copper alloy, which has high tensile strength and wear resistance.

Cadmium (nickel (Alloy is the bearing material used in aircraft engines. Cadmium is found in many low-melting alloys, and cadmium is found in the well-known Wood fusible alloy.

2.Cadmium has a large thermal neutron capture cross-section, so alloys containing silver (80%), indium (15%), and cadmium (5%) can be used as (neutron absorption) control rods for atomic reactors.

3.Cadmium compounds have been widely used in the manufacture of (yellow) pigments, plastic stabilizers, phosphors (TV tubes), pesticides, fungicides, paints, etc.

4.For rechargeable batteries: nickel-cadmium and silver-cadmium, lithium-cadmium batteries have the advantages of small size and large capacity.

5.Cadmium is also used in the manufacture of electrical alloys, such as the electrical contacts in electrical switches are mostly made of silver cadmium oxide materials, which have the advantages of good conductivity, small arc ignition, and good resistance to welding[3], and are widely used in household appliance switches, automotive relays, etc. [4], but because cadmium is toxic and affected by the EU Waste Electrical and Electronic Equipment Directive (WEEE) and the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) directives [5], The silver cadmium oxide material in the electrical switch is gradually replaced by environmentally friendly materials such as silver tin oxide and silver nickel material.

Cadmium, a heavy non-ferrous metal element, chemical symbol CD, atomic number 48, discovered in 1817.

The elemental silvery-white metal, which is an excellent neutron-absorbing metal, is made into rods that slow the rate of chain fission reactions in nuclear reactors and is useful in zinc-cadmium batteries. Its sulfide is bright in color and is used to make cadmium yellow.

The ratio of matter to cadmium in the earth's crust is 1,000,000:. It is extracted as a by-product from zinc ore or thiocadmium ore, and is mostly used to protect other metals from corrosion and rust, such as galvanized steel, ironwork, copper, brass and other alloys. Another use is to make a bright yellow pigment called cadmium yellow, which can be used as a high-grade paint and painting pigment.

Cadmium contamination:

Cadmium is a non-essential element of the human body, which often exists in the state of compound in nature, and the content is generally very low, and it will not affect human health under normal environmental conditions. Cadmium and zinc are cogenerics, and cadmium often coexists with zinc and lead in nature. When the environment is polluted with cadmium, cadmium can accumulate in living organisms and enter the human body through the food chain to cause chronic poisoning.

After cadmium is absorbed by the human body, cadmium thiophalin is formed in the body, which selectively accumulates in the liver and kidneys.

The above content refers to Encyclopedia - Cadmium.

Cadmium is a chemical element with the symbol Cd and atomic number 48. It is an off-white, lustrous metal with good machinability and ductility. Cadmium has the characteristics of high density, low melting point and weak electrical conductivity.

It has a wide range of applications in batteries, alloys, coatings, plastics, and other fields, but excessive intake of cadmium can cause harm to human health, such as kidney and bone diseases. Therefore, it is also a top priority to strengthen the supervision and control of cadmium to ensure people's health.

Cadmium is a nutrient that the body needs, mainly stored in the liver and kidney function, which can promote the metabolism of human fat and adjust the metabolism of insulin glargine. Cadmium is toxic, the amount of the human body needs is very small, we can get cadmium according to the ingredients, for example, meat and milk are all with cadmium.

Cadmium is a heavy non-ferrous metal element, which is detailed below:

1. Introduction: cadmium heavy non-ferrous metal element, chemical symbol CD, atomic number 48, found in 1817 that the element is silvery-white metal, is an excellent metal that absorbs neutrons, made of rods can slow down the chain fission reaction rate in nuclear reactors, and is quite useful in zinc-cadmium batteries. Its sulfide is bright in color and is used to make cadmium yellow pigment.

It is mostly used to protect other metals from rust, such as galvanized steel, ironwork, copper, brass and other alloys. Another use is to make a bright yellow pigment called cadmium yellow.

2. Physical properties: cadmium is a silvery-white shiny metal with toughness and ductility. Cadmium slowly oxidizes in moist air and loses its metallic luster, forming a brown oxide layer on the surface when heated, and cadmium oxide fumes are produced when heated above the boiling point.

At high temperatures, cadmium reacts violently with halogens to form cadmium halide. It can also be directly combined with sulfur to form cadmium sulfide. Cadmium is soluble in acids but insoluble in alkalis.

3. Determination method: The cadmium content of most fresh water in the field of environmental engineering is less than 1 microgram, and the main source of cadmium pollution is the wastewater discharged from electroplating, mining, smelting, dye, battery and chemical industry. Methods for the determination of cadmium in environmental monitoring include atomic fluorescence spectrometry, atomic absorption spectrophotometry, dithione hydrazone spectrophotometry, anodic dissolution voltammetry and oscillopolarography.
