Wear Resistance Polished Zro2 Ceramic Shaft
Description:
Ordinary alumina ceramics are classified into 99 porcelain, 95
porcelain, 90 porcelain, 85 porcelain, etc. according to the
content of Al2O3. Sometimes the content of Al2O3 is 80% or 75%,
which is also classified into ordinary alumina ceramic series.
Among them, 99 alumina ceramic materials are used to make high
temperature crucibles, refractory furnace tubes and special
wear-resistant materials, such as ceramic bearings, ceramic seals
and water valve sheets; 95 alumina ceramics are mainly used as
corrosion-resistant and wear-resistant parts;
