white 95% purity high precision wear resistance zirconia ceramic rod
With excellent physical and chemical properties, Zirconia ceramics has not only become a research hotspot in the field of scientific research, but also widely used in industrial production. Zirconia ceramics is an important raw material of refractories, high-temperature structural materials and electronic materials.
Among all kinds of metal oxide ceramic materials, zirconia has the best thermal stability and heat insulation performance at high temperature.
The main raw material is zirconia ceramic pigment, which is an important component of high - quality glaze.The thermal conductivity of zirconia is the lowest in common ceramic materials, and the coefficient of thermal expansion is close to metal materials.Special crystal structure makes it an important electronic material.
