Description
Zirconium Silicate 65% Zircon Flour
Zirconium Silicate 65% Zircon Flour (CAS 10101-52-7, molecular formula ZrSiO4) 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 ZrO2 + HfO2 65% 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 Zircon Flour, Zircon Opacifier, Zirconium Orthosilicate. 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
- Opacifier in ceramic tile and sanitaryware glazes
- Whitening agent in tableware and porcelain enamel
- Refractory aggregate in foundry and furnace linings
- Investment casting mould facing
- Abrasive and grinding media manufacture
