Zircon sand (zircon stone) is used in the production of refractory materials (called zircon refractories, such as zirconium corundum bricks, zirconium refractory fibers), casting sand (precision casting sand), precision enamel appliances, and glass, metal (sponge zirconium) and zirconium compounds (zirconium dioxide, zirconium chloride, sodium zirconate, potassium fluozirate, zirconium sulfate, etc.). Can make glass kiln zirconia bricks, zirconia bricks for steel drums, ramming materials and castables; Adding to other materials can improve its properties, such as adding zirconium sand to synthetic cordierite, can broaden the sintering range of cordierite, but does not affect its thermal shock stability; Zirconium sand is added to high alumina brick to make high alumina brick resistant to spalling, and the thermal shock stability is greatly improved. It can also be used to extract ZrO2. Zircon sand can be used as high-quality raw sand for casting, and zircon sand powder is the main component of casting paint.
