Precision Metallurgy Casting Zircon Sand

Zircon sand, also known as zircon sand and zircon, is a mineral mainly composed of zirconium silicate. Pure zircon sand is colorless and transparent crystal, which is often dyed into yellow, orange, red, brown and other colors due to different origins and different types and quantities of impurities. 4.6~4.71, the change of specific gravity is sometimes related to the composition and alteration state. The cleavage of zircon is incomplete, the uniform Mohs hardness is 7~8, the refractive index is 1.93-2.01, and the melting point varies with the impurities contained within 2190~2420ºC fluctuation.

Applications:

Zircon sand is extremely resistant to high temperatures,with a melting point of 2750 degrees Celsius.And acid corrosion resistance 80% of the world's direct use in foundry industry,ceramic,glass industry and the manufacture of refractory materials.A small amount is used in ferroalloys,medicine,paint,tanning,abrasives,chemical and nuclear industries.A very small amount is used to smelt metal zirconium.
