Executive Standard: B/T6890-2012
Product characteristics: molecular formula: Zn, molecular weight: 65.38
Physical properties: dark gray metal fine powder
Density : 7.14g/cm3, melting point: 419.4°C, boiling point: 908°C
Chemical properties: insoluble in water, soluble in acid and alkali, slowly soluble in acetic acid, ammonia, with strong reducibility, and hydrogen evolution with acid and alkali. Moistened by moisture, stable in dry air, and white basic carbonate formed in moist air to cover the surface. The air burns a blue-green flame to produce zinc oxide. High purity reacts slowly with sulfuric acid and nitric acid, and accelerates when a small amount of other metals such as steel, tin, and lead are contained.
Product uses: organic, inorganic chemicals, pharmaceuticals, pesticides, printing and dyeing, metallurgy, reducing agents, catalysts and other industries.
A-Sub-nano zinc powder for coating
B-Special zinc powder for anti-corrosion coating
C-Special zinc powder for sheradizing

Founded in 2007, our company is situated in the scenic Tianmu Lake. Now, our company is a high-tech enterprise engaging in the production, processing and trade of high-performed zinc products.
Our company has developed a zinc powder production furnace using clean energy natural gas as a fuel; through replacing the original coal and gas commonly used in China, we have greatly improved the stability and sustainability of zinc powder production at high temperature. Thus the zinc content of our zinc powder is far exceeding that of similar products, with features as large zinc powder output, low lead chromium and other impurities, environmental and healthy.
