Yttria Stabilized Zirconium 8Y

Yttria Stabilized Zirconium 8Y

Introduction of Yttria Stabilized Zirconium 8Y

8Y Yttria Stabilised Zirconia we supplied is a kind of non-toxic, tasteless, white powder, Yttria stabilised zirconia has enough stability in alkali solution and lots of acid solution, except hot concentrated H2S04, HF and H3P04, with strong thermal shock resistance, high temperature resistance, good chemical stability features. 8% mol yttria stabilised zirconia compound other materials (Al2O3, SiO2) could greatly improve the performance of material parameters, the fracture toughness, flexural Make high-tech composite materials with high temperature resistance, corrosion resistance, wear resistance and other good characteristics. In order to improve the performance of ceramics, 8% mol yttria stabilised zirconia powder is sprayed to granulation by advanced high-speed centrifugal scatter method, the advantages of 8Y yttria stabilised zirconia are good dispersion and liquidity, very small microscopic grains, uniform the grain size distribution, no agglomeration,and yttria stabilised zirconia is good for molding and pressing of the ceramic, increase the density of ceramics. So after through dry pressing molding and isostatic pressing molding of ceramic green body is with high density and strength, smooth surface, uniform inside and outside, not easy break and low porosity.

Applications

1.YSZ powder commonly used as electrolyte in solid oxide fuel cell (SOFC), Y2O3 content at 8% YSZ , namely 8Y yttria stabilised zirconia has the best comprehensive performance, , the biggest electrical conductivity and one of the most widely used. With high stability in the oxidation and reduction atmosphere, and high temperature stability of cubic phase ZrO2 could be kept until room temperature, so that 8Y yttria stabilised zirconia is considered to be the best candidate for the industrialization of SOFC.

2.The conductivity of 8Y Yttria doped zirconia electrolyte material has close relationship with sintering temperature of ceramic body. 8Y Yttria doped zirconia polycrystalline material is composed of grain, grain boundary and porosity, the existence of pores can reduce the grain boundary and conductivity of the material, also improve the sintering temperature of ceramic body and gradually shrinking, as well as reduce connecting hole of grain boundary. Thus, 8% mol Yttria doped zirconia polycrystalline material could improve the sintering density of porcelain body, increase the conductivity of the material and the high temperature could reach1450℃ in maximum.

3.8% mol Yttria doped zirconia as solid electrolyte used in electrochemical oxygen sensors, solid oxide fuel cell (SOFC) and oxygen pump, also applied in heating equipment in the oxidizing atmosphere when temperature is 2000℃, and etc. Zirconium sensor has become the main technology and device in car engines and industrial burner controller. It is one of the key components to reduce fuel consumption, save energy and reduce air pollution.


Process

The main steps of yttria stabilised zirconia powder by chemically coprecipitation method: mixing ZrOCl2 with YCl3 solution, then through coprecipitation, water washing, alcohol aging, low temperature drying, calcination, ball mill, airflow crushing, and sieving. Generally speaking, in order to improve the performance of ceramics, Yttria doped zirconia powder will be granulated by high-speed centrifugal spray.
