## **OMEGATITE[®] 450** 

## **OMEGATITE 350** 

This is an impervious, recrystallized, pure alumina ceramic containing over 99.8% Al2O3. It has the most superior gas and vacuum tightness and electrical insulating properties at elevated temperatures. It is non-reactive and recommended for use with platinum, as well as tungsten and molybdenum thermocouple alloys. The maximum service temperature is 1900°C (3450°F).
