Zirconium Tungstate

Zirconium tungstate is a green light powder. Chemical formula of zirconium tungstate is ZrW2O8 and the molecular weight is 586.9. Its relativity system numbers are as follows: CAS number: 16853-74-0, MDL number: MFCD00168096, EINECS number: 240-876-3. It is stable at room temperature and atmospheric pressure, but should to avoid the light, flame and heat. Besides, it can be sealed and stored in tight, dry and airy place where away from light. Although ZrW2O8 to water is not harmful, but if there is no relevant government license, the material can not discharged into the surrounding environment. There are many ways for produce zirconium tungstate such as impregnation method, oxide direct synthesis method, co-precipitation method, combustion method, sol-gel method, spray drying method and hydrothermal synthesis method and so on.
Zirconium tungstate as raw materials are mainly used in engineering ceramics, electronic ceramics, metal matrix composites, ceramic matrix composites, cement-based composite materials, the optical devices, dental materials. In addition, because the unique cubic crystal structure of zirconium tungstate it can as the negative thermal expansion material which has been widespread concern.
