5 FAQs of 99 alumina ceramic furnace tube

Frequently Asked Questions About 99% Alumina Ceramic Furnace Tubes

What is a 99% alumina ceramic furnace tube?

This tube is made from high-purity aluminum oxide (Al₂O₃), with 99% of its content being alumina. It can handle very high temperatures and resists wear, corrosion, and thermal shock. People use it in labs and industries where stable performance at extreme heat is needed.

What temperature can it handle?

The tube works safely up to 1750°C (3182°F) in air. Its exact limit depends on the atmosphere inside the furnace and how long it runs. For best results, stay below 1700°C during continuous use.

Why choose 99% alumina over other ceramics?

99% alumina offers better strength, purity, and thermal stability than lower-grade ceramics like 95% or 90% alumina. It also has low reactivity, so it won’t contaminate sensitive materials during heating processes like sintering or crystal growth.

Can it be used in vacuum or reducing atmospheres?

Yes, but with care. In vacuum or hydrogen-rich environments, the maximum safe temperature drops—usually to around 1600°C. Always check your specific process conditions before use to avoid cracking or weakening the tube.

How do I install and handle the tube?

Handle it gently—it’s strong under heat but brittle at room temperature. Avoid sudden impacts or stress. When installing, make sure supports are even and allow room for thermal expansion. Clean it with soft tools only; never use metal brushes or sharp objects.
