Fused zirconium dioxide is a kind of brand new high-grade refractory materials. It has high melting point, thermal stability, chemical stability and so on refractory properties, widely used in zirconia ceramics, glass kiln, refractory materials, electronics, grinding media, metallurgy, machinery, chemical, refractory manufacturing and other industries. When the temperature is in 20 ~ 1000℃, ZrO2 thermal conductivity is 1.51 ~ 2.2 W•m-1•K-1, The production method of fused zirconium dioxide is by premium zircon (ZrSiO4 or ZrO2. SiO2) as raw material, carbon as the reducing agent, and adding a small amount of catalyst or stabilizing agent in the high-temperature electric arc furnace, decomposition and restore the zircon sand. According to the different melting point between zirconium oxide and silicon dioxide, silicon powder is separated from zircon sand and directly recycle by recycling system. Zirconium dioxide is by compressed air blowing into the bubble zirconia, then through screening, crushing and milling process, at last packing and storage. The advantage of electric smelting method is that the products with low production cost, stable product performance and lower environmental pollution.

Firstly, we import high quality Australian zircon sand as raw material, with the right amount petroleum coke as reducing agent to join the electric arc furnace, the zircon sand is firstly decomposed into ZrO2 and SiO2 under the action of electric arc heat, then SiO2 react with carbon to generate gaseous SiO2 and was discharged with the flue gas by draught fan.
Secondly, to avoid producing into zirconium carbide, we strictly control the dosage of reductant carbon. After totally get rid of SiO2 from the arc furnace, then the melt molten state of zirconium oxide dump out from the arc furnace, and by compressed air blowing into the bubble zirconium. According to different applications, then through screening, Raymond mill or Jet mill process into different particle size products.
At last, packing and storage. Silicon powder directly recycled by recycling system.
1.Ceramic glazes and ceramic pigment
Fused zirconium dioxide is one of the main color raw materials, used for producing zirconium ceramic pigment, such as：zirconium blue pigment, turquoise Pigment, vanadium zirconium yellow, blue vanadium, zirconium iron pink (Zr-Si-Fe), and etc. The 50% to 60% of the total fused zirconia are used in ceramic glazes industry. The ceramic glazes and colors could be resistant to high temperature calcination process in ceramic industry which are used in decorated sanitary ceramics, tableware, floor tile and wall brick
2.Refractory materials, refractory manufacturing and casting industry
Firstly, fused zirconium dioxide is used in continuous casting refractory manufacturing, especially use in the constant pressure products, include liquid outlet, slide gate nozzle brick, stopper, submerged nozzle of ladle and intermediate tundish. Second, fused zirconium dioxide is also used in sliding baffles, especially for the highest temperature area in the center of exposed. Compared with the corresponding aluminum carbon material, fused zirconium dioxide product has better oxidation resistance, thermal shock resistance, erosion resistance and higher strength, longer service life and so on refractory properties. Another is for the use of glass industry
The investment casting is another major specialized market for fused zirconium oxide. The specialty casting products, such as aerospace engines, using zirconium oxide as coating of the model. applying in the turbine engine blades and golf clubs, and etc.
Fused zirconium oxide products are used in grinding steel and metal alloys as grinding media.
