Description
Zirconium silicate is used as an opacifier in ceramic glazes, giving tile and sanitaryware their bright white, opaque surface.
What it is: Typically supplied as zirconium silicate, valued for the opacity and chemical and abrasion resistance it adds to a fired glaze.
Key applications: Ceramic glazes, where it blocks light transmission and produces the uniform white, opaque finish expected on tile and sanitaryware surfaces.
Why it matters: It is usually positioned alongside feldspars and China Clay as part of a full ceramic body and glaze formulation, rather than sourced on its own.
