Small diameter of high alumina ceramic tubes made in China
1. Extreme high temperature stability under reducing, inert and high vacuum condition under high temperature up to 1800C.
2. Extreme wear and abrasion resistance.
3. Chemical corrosion resistance under high temperature.
4. High dielectric properties.
5. Gas tight for many applications to provide protective atmospheres or high vacuum at high temperature to eliminate contamination or impurity.
