Ceramic property values vary somewhat with method of manufacture size and shape of part.
Alumina ceramic specific heat.
High purity alumina is usable in both oxidizing and reducing atmospheres to 1925 c.
Heat resistance up to 1300 c.
Variations are possible among various commercial grades.
Property values below are taken from literature and manufacturer sources.
Excellent resistance to high vacuum up to 10 8 torr we can provide alumina silicate.
Rubbing tests are run using a dry 240 grit fused alumina abrasive.
Weight loss in vacuum ranges from 10 7 to 10 6 g cm 2 sec over a temperature range of 1700 to 2000 c.
The indices in the chart are calculated by dividing the material volume loss by the volume loss of an ad 85 alumina control.
