  Zinc Oxide 90-98% (Direct method) Molecular Formula: ZnO Molecular Weight: 81.39 CAS: 1314-13-2 EINECS: 215-222-5 Appearance: White powder Properties: White powder, odorless, tasteless, non-sandy. If the heat becomes yellow, then restore the white of cooling, the proportion of 5.606, melting point of 1975 degrees Celsius, hiding power than white lead is small, is TLO2, curing Znic 1 / 2, the coloring is white lead 2 times. The difference with the white lead sulfide is encountered the same black, let the acid, alkali, ammonia and ammonia chloride, insoluble in water and alcohol, when the absorption of CO2 in the air, Property change. Application: T Mainly used for rubber products and rubber reinforcing agent and sulfur to help promote the agent, and the paint film enhancer, but also as a hard glass, optical glass, catalysts and medical rubber ointment of raw materials, petroleum refining, paint and batteries, etc. Has also been widely used. Specification: Purity (calculated in ZnO ): 90-98% Lead oxide: 0.2% max Cadmium oxide: 0.02% max Copper oxide: 0.006% max Mn: 0.0002% max Zn: none Insoluble in hydrochloric acid: 0.02% max Loss on ignition: 0.4% max Soluble matters in water: 0.4% max Sieve residue (320 mesh): 0.2% max Water: 0.5% max Covering power g/m2: 150 max Oil absorption g/100g: 20 max Colour killing: 95 max Color (compared with standard sample): pass Packing: 25kg woven bag
