Zinc Oxide 99.7% Indirect Process

Zinc Oxide 99.7% Indirect Process (CAS 1314-13-2, molecular formula ZnO) is a raw material for tile, sanitaryware, tableware and refractory production, where particle size and impurity profile drive fired colour and body strength. China Chemicals supplies it at 99.7% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Chinese White, Zinc White, Calamine. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Glaze flux improving gloss and craze resistance
Rubber vulcanisation activator
White pigment in paint and coating systems
Ferrite and electronic ceramic manufacture
UV absorber in sunscreen and personal care
