Nanjing active zinc oxide prices

Formula: ZnO Molecular Weight: 81.384 technical indicators: GB / T3185-1992 Performance: zinc oxide, also known as zinc oxide powder, zinc white, is an important inorganic chemical raw materials as a white powder, is stable at room temperature, has a good hiding power and tinting strength . Insoluble in water and alcohol, it can melt in acid, alkali and ammonium salt solution. Indirect method zinc oxide Zincoxide CASNo:. 1314-13-2 Quality Index (Specification) Appearance (Appearance): white hexagonal crystal or powder Content (Purity): 99.7% Properties (PhysicalProperties) metal (as Zn)% : none; lead oxide (Pb): ≤0.037%; manganese oxide (based on Mn): ≤0.0001%; ??copper oxide (with Cu): ≤0.0001%; ??loss on ignition: ≤0.2%, Water soluble matter: ≤0.10%; Moisture: ≤0.3%; sieve residue (320 mesh): ≤0.10% indirect method generally zinc ingots as raw material by electrolytic reduction, made of zinc oxide, zinc ingots of different raw materials, production the purity zinc oxide are not the same, this process is mainly produced 99.5% - 99.7% zinc oxide. Indirect method zinc oxide implementation of standards GB / T3185-92, the main raw material feedstocks other ingot, the dross is the indirect method zinc oxide. Technology is good, pure zinc, the production of zinc oxide content of 99.8% can be achieved. Usage: rubber, paint, ink, cables, electronics, coinage, enamel, matches, chemicals solution, phosphate solution, metal surface treatment, cosmetics and other industries as raw materials. Packing: PP woven bag or kraft paper bag lined with plastic film bag, net weight 25kg. Storage: waterproof, moisture-proof, anti-hook, avoid contact with high temperature and pH.
