Zirconia ceramic tube accurate size polishing high temperature resistance spinning machinery fitting
product name:
model:HY-YH01
Product description:
Zirconia is an inorganic non-metallic material with superior performance and acid and alkali resistance. It has stable chemical properties, high melting point, small thermal conductivity, hardness, high strength and wear resistance. The superiority of zirconia properties makes zirconia and its products become one of the main raw materials of structural ceramics, functional ceramics, bioceramics and thermal coating ceramics. It has a wide application prospect in military industry, energy, metallurgy, electronics, communication, automobile, machinery and other high-tech fields.
