The important role Of ZrO2
2015-09-17
Zirconium oxide fiber is one kind of amorphous refractory fiber material. Duo to the high melting point and other high temperature properties, which makes zirconium oxide fiber have higher using temperature than alumina fiber, mullite fiber, aluminum silicate fiber and other refractory fiber. Zirconium oxide fiber can be long-term used in high temperature which may over 1500 ℃, and the maximum using temperature of zirconium oxide fiber is up to 2200 ℃, even keep completed shape when temperature reach to 2500 ℃. So zirconium oxide fiber is one of the world's top refractory fiber materials with the properties of stable chemical performance, anti-corrosion, antioxidant, anti heat shock, non volatile and no pollution
ZrO2 plays an important role in glass refractory and it is an important chemical composition of zircon related refractory, such as fused cast azs block, zircon brick, fused cast high zirconia brick and zircon mullite brick. ZrO2 is a white crystalline which is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. ZrO2 has the characteristics of high melting point, high resistance coefficient, high refractive index and low thermal expansion coefficient.
Industry used zircon is stable zirconium oxide which is made by electric melting method, adding carbon and stabilizer of calcium oxide during the electric melting process, meanwhile, silicon, zirconium oxide and calcium oxide form solid solution, then through crushing and whole grain processing, stable zirconium oxide is made.
Zhengzhou Sunrise Refractory Co., Ltd. is mainly engaged in the research and development of refractory products. Sunrise can provide excellent quality of zircon related products such as fused cast AZS block 33#,36#,41#, fused cast high zirconia block, zircon brick, zircon mullite brick. Over 30 years producing and marketing experience, with reliable quality, competitive price and prompt delivery, Sunrise has established long-term business and cooperation relationship with many customers in different countries and regions.
