Zircon is extremely resistant to high temperatures, with a melting point of 2750, and is resistant to acid corrosion. 80% of the zircon in the world is directly used in the foundry industry, ceramics, glass industry and the manufacture of refractories. A small amount of zircon is used in ferroalloy, medicine, paint, tanning, abrasives, chemical and nuclear industries. A very small amount of zircon is used to smelt metal zirconium. The zircon sand containing ZrO265~66% is due to its melting point (melting point above 2500℃)
Zircon powder has low thermal expansibility, high thermal conductivity and strong chemical stability, insoluble in acid and alkali, non-magnetic, weak electrical. It mainly used in foundry industry, refractory industry, ceramic industry, paint industry and chemical industry and so on.
1. Investment casting molding materials, aggregates for coatings.
2. Foundry industry, ceramics, glass industry and manufacturing refractory materials.
3. A small amount is used in ferroalloy, medicine, paint, tanning, abrasives, chemical and nuclear industries
