The technical advanced ceramics offer considerable advantages against metal and plastic. They maintain their dimensional stability in the high temperature range (> 1000 ° C). They are excellent electrical insulators. They show high wear resistance and do not degas under vacuum. In addition, the technical advanced ceramics are inert materials and corrosion resistant to gas, acid and plasma environment. Therefore, the ceramics are important materials in the wafer treatment process. UNIPRETEC offers various ceramic components for semiconductor industry.
