Zirconium Silicates — M.L. Enterprises

Since 2010 we have been engaged in trading & exports of ceramic products — very high quality Zirconium Silicates & Zirconium Flours for ceramics. We mostly supply Zirconium-2, Zirconium-5 and Zirconium Flour (325 mesh) to ceramic industries.

Application of Zirconium Silicates

Opacifier for pottery and porcelain glazes, wall tiles, roofing tiles, sanitary ware etc.
Frits, glazes & enamels
Admixture for ceramic body (improvement of property and opacification of colour)
