Description

Zirconia powder and dolomite react together at high temperature to produce zirconium dioxide or zirconium oxide (ZrO₂). Zirconium oxide is also a high-quality refractory material, although its crystal shape changes with temperature. Stable zirconium oxide also contains a small amount of oxides of magnesium, calcium, scandium or yttrium. The melting point of stable zirconium oxide is close to 2700. It resists thermal shock and is less reactive than zircon in some metallurgical applications. Stable zirconium oxide has low thermal conductivity. In industrial zirconium oxide, hafnium dioxide is harmless when used as a refractory.

Product Application:

Zirconium silicate powder containing ZrO₂ 65～66% is directly used as the casting material of iron metal in foundries because of its melting point (melting point above 2500℃). Zirconium silicate powder has lower thermal expansion, higher thermal conductivity, and stronger chemical stability than other common refractory materials, so high-quality zircon has good adhesion with other various adhesives It is used in the foundry industry. Zircon sand is also used as bricks in glass kilns. The zircon sand and zircon powder mixed with other refractory materials have other uses.

Zirconium silicate powder is used in refractory materials (called zirconium refractory materials, such as zirconium corundum bricks, zirconium refractory fibers), sand for casting in the foundry industry (precision casting sand), precision enamel appliances, and also Production of glass, metal (zirconium sponge) and zirconium compounds (zirconium dioxide, zirconium oxychloride, sodium zirconate, potassium fluorozirconate, zirconium sulfate, etc.). It can be used to make zircon bricks for glass kilns, zircon bricks for steel drums, ramming materials and castables; adding to other materials can improve its performance, such as adding zircon sand to synthetic cordierite to broaden cordierite The sintering range is high without affecting its thermal shock stability; zircon sand is added to high alumina bricks to make anti-stripping high alumina bricks, which greatly improves thermal shock stability; it can also be used to extract ZrO₂. Zircon sand can be used as high-quality raw sand for foundry, and zircon sand powder is the main component of coating for foundry.
