Stainless Steel refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, the maximum does not exceed 1.2%, and the Wc (carbon content) of some steels is even lower than 0.03% (such as 00Cr12 ).
Nickel is a silvery-white metal with a yellowish tint and is a magnetic transition metal. Electrolytic nickel is nickel made using electrolysis (electrolysis in a solution of nickel sulfate). The enriched sulfide ore is roasted into oxides, reduced to coarse nickel with carbon, and then electrolyzed to obtain pure metal nickel. Nickel is used as a catalyst for hydrogenation reactions in the chemical industry.
Cobalt is a shiny, steel-gray metal with a melting point of 1495°C and a specific gravity of 8.9. It is relatively hard and brittle. Cobalt is ferromagnetic and is similar to iron and nickel in terms of hardness, tensile strength, machinability, thermodynamic properties, and electrochemical behavior. Metal cobalt is stable in humid air and water at normal temperatures and does not react with alkalis or organic matter. Oxidation occurs at high temperatures.
Lithium carbonate (Li2CO3) is the most important lithium salt among lithium compounds, and is the main raw material for preparing other high-purity lithium compounds and lithium alloys. Therefore, Li2CO3 production is one of the most basic and critical links in the lithium industry. The rapid development of the lithium battery industry in recent years has led to a substantial increase in the demand for Li2CO3, the main raw material for the production of lithium battery cathode materials.
Sulfur, also known as sulfur, is a non-metal elemental substance with the chemical formula S. It is a light yellow brittle crystal or powder with a special odor. It is insoluble in water, slightly soluble in ethanol and ether, and easily soluble in carbon disulfide. As a flammable solid, sulfur is mainly used in the manufacture of dyes, pesticides, matches, gunpowder, rubber, rayon, etc.

Indium is a silvery white and slightly light blue metal with a melting point of 156.61°C, a boiling point of 2080°C and a density of 7.3 g/cm3 (20°C). It is soft enough to be scratched with a fingernail and less hard than lead. Indium has strong plasticity and ductility, and can be pressed into extremely thin metal sheets.
Praseodymium neodymium oxide, molecular formula (PrNd)xOy, properties and appearance is gray or brown powder, easy to absorb water and air, must be stored in a dry place, not in the open. For deep processing and glass, ceramics, magnetic materials, etc. The gray powder of praseodymium-neodymium oxide is the raw material of metal praseodymium-neodymium ,and the metal praseodymium-neodymium is formed after high-temperature melting and processing of praseodymium-neodymium oxide.
Ammonium paratungstate is a chemical substance with the molecular formula (NH4)10W12O41·5H2O. Monoclinic fine transparent crystal or white crystal. Heating in the air, when the temperature is lower than 100°C, part of the ammonia molecules will be removed, and all the ammonia molecules and crystal water will be removed when the heat is strong, and it will turn into a yellow powder of tungsten trioxide. Decompose in acid and alkali solution. It is used to make metal tungsten powder made of tungsten trioxide or blue tungsten oxide. It is also used to manufacture ammonium metatungstate and other tungsten compounds, which are used as additives in the petrochemical industry.
