Zinc oxide is a zinc molecular entity. Zinc oxide is an inorganic compound used in a number of manufacturing processes. It can be found in rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and firstaid tapes. It occurs naturally as the mineral ...
Get PriceThe resultant zinc oxide is further ground and mixed with coke (a highcarbon content fuel) and then heated to 1400 o C. The coke serves as a reducing agent, and the zinc oxide is reduced to metallic zinc via the following reaction; 2ZnO + C → 2Zn + CO 2. The zinc obtained in this method is in a gaseous state, as its boiling point is below ...
