Specification of Bahan Kimia - Zinc Oksida
Zinc oxide is an inorganic compound with the formula ZnO. This is a white
powder that does not dissolve in water. This powder is widely used as an
additive and many products including plastics, ceramics, glass, cement, rubber
(for example, car tires), lubricants, paints, ointments, adhesives, sealants,
pigments, food (sources of Zn nutrition), batteries, fire extinguisher , etc.
ZnO is present in the earth's crust as a mineral of zinc, however, the most
widely used commercial ZnO is synthetic ZnO.
