Diamond Polished Wear Resistance Precision Alumina Zirconia Ceramic
Piston
Description:
The Ceramic piston is made of high-purity ceramic raw materials,
which are formed by dry pressing or cold isostatic pressing,
high-temperature sintering and precision machining.Ceramic piston
can work in the acid and alkali corrosion conditions, high
toughness and low friction coefficient, high pressure environment
for a long time, and the maximum temperature to 1800 ºC
(3272ºF)...Molding process is mainly hot, dry pressure, isostatic
pressing; Products alumina purity to meet customer requirements.
