Chinese name: Zinc powder English name: zinc powder Chinese name 2: lead powder English name 2: Zinc dust Molecular formula: Zn Molecular weight: 65.39 Basic physicochemical properties: Color: dark grey; Molecular structure: spherical; Average gravity: 7.14g /cm33; Melting point: 419â??; Boiling point: 907â??. Solubility: insoluble in water, soluble in acid and alkali, ammonia; Stability: has a strong reducibility, and acid and base action to release hydrogen, easy to burn, combustion; Stable in dry air, a large amount of zinc powder can be burned in humid air; Burning in hot air produces a blue flame and produces zinc oxide. Flying in the air, the encounter of Mars can cause combustion, the allowable concentration in the air is 15mg/m3; It is easily caked by moisture, forming white basic carbonate in moist air and coating the surface; The reaction with sulfuric acid and nitric acid is slow, and the reaction is accelerated when there is a small amount of other metals such as copper, tin and lead. ã?? Main uses of metal zinc powder ã?? Huiyuan brand metal zinc powder is widely used in medical intermediates, electronic materials, military materials, zinc salt chemical industry, anticorrosive coatings, nonferrous and rare metal smelting and other industries.

Ir Bal. Pt 0.002 Pd 0.001 Rh 0.003 Ru 0.001 Au 0.001 Ag 0.001 Fe 0.001 Cu 0.002 Application: 1. Iridium is the only precious metal thermocouple that can measure temperature up to 2100 C in the atmosphere because of its high temperature oxidation resistance and thermoelectric properties. Iridium can be used as a container material for radioactive heat source. Iridium anodic oxide film is a promising electrochromic material. Ir192 is a gamma ray source, which can be used for nondestructive testing and radiochemical therapy. Iridium is also an important alloying element; 2. Iridium powder/Iridium gold melting into gold can increase the weight, hardness and density of gold, generally adding about 5%~30%(K gold) of gold weight for mixed melting; 3. It is used for electronic pastes, reduce the sintering temperature of the electronic pastes; 4. It is used for welding of alloy, reduce the alloy melting point; 5. It's for in the alloy, improve the abrasion resistance of alloy; 6. It's for lubricants, improve the wear resistance of lubricating oil; 7. In the application of coatings, improve transparency and abrasion resistance, resistance to scratch and conductive ability;
