Product Description
Zirconia Ceramic:
Zirconium oxide ceramics are white, yellow or gray when containing impurities, and
generally contain HfO 2, which is not easily separated. Pure ZrO2
has three crystal states under normal pressure. The production of zirconia ceramics requires the preparation of high-purity, good dispersion
properties, ultra-fine particles, narrow particle size
distribution, zirconia ultrafine powder preparation methods,
zirconia purification mainly chlorination and thermal
decomposition, alkali metal Oxidative decomposition method, lime
melting method, plasma arc method, precipitation method, colloid
method, hydrolysis method, spray pyrolysis etc.
In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics because of
their high toughness, high flexural strength and high wear
resistance, excellent thermal insulation properties, and thermal
expansion coefficient close to that of steel.
Properties
High strength, high hardness, crash resistance, wear resistance,
corrosion resistance, smooth surface, low thermal conductivity,
nonmagnetic etc.
