Potash Feldspar 200 Mesh Ceramic Grade

Potash Feldspar 200 Mesh Ceramic Grade (CAS 68476-25-5, molecular formula KAlSi3O8) 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 K2O 10% 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 Potassium Feldspar, K-Spar, Microcline. 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

Flux in porcelain, tile and sanitaryware bodies
Glaze and frit raw material
Glass batch flux reducing melting temperature
Filler in paint, rubber and plastics
Welding electrode coating
