high temperature resistant alumina ceramic tube for furnace and kiln,

both end open

Features:

1 High dielectric properties.

2 Extreme wear and abrasion resistance.

3 Chemical corrosion resistance under high temperature.

4 Extreme high temperature stability under reducing, inert

and high vacuum condition under high temperature up to 1800C.

5 Gas tight for many applications to provide protective atmospheres

or high vacuum at high temperature to eliminate contamination or impurity.
