2. 55%58%60%64%65% zircon flour Introduce
High-grade supper fine zirconium silicate is produced under strict processing and quality control of laboratory conditions, it is recommended use for high-quality enamel ware
3. Usage
(1) Emulsifying agent used in all types of ceramic glaze: coffee cup, sanitary ceramics, wall and floor tiles, construction tile and brick, coarse ceramic, tableware, special ceramic etc.
(2) Plastic Industry
Formulations for epoxy resins, sealing resin, filling material for silicone, vinyl resins which to increase the heat resistance and insulation resistance value, filling material for inert, dense, white, and chemical resistance need materials
(3) Refractory
Zirconium casting refractory for glass melting furnaces; heat-resistant porcelain; Refractory casting sand; the HPL red sand; special fire-resistant porcelain; refractory cement.
