Instructions for use
When using alumina furnace tubes, it is best to control the heating and cooling rate to 5 degrees / minute, the slower the better.
Rapid cooling and rapid heating are one of the main reasons for the rupture of the alumina furnace tube. Our products have good resistance to quenching and heating.
Please keep the alumina furnace tube clean at all times, do not leave some samples in the alumina furnace tube, one side chemical reaction and cracking of the alumina furnace tube. It is recommended to put the test sample into the crucible and alumina furnace tube.
During lofting and sampling, it is best to be within 200 degrees and slowly push from the edge to the middle. High temperature sample delivery and sampling is also the main reason for corundum tube rupture.
Make sure to place mullite plugs on both sides of the alumina furnace tube to prevent heat radiation from damaging the silicone ring in the flange. The crucible should be placed in the middle of the alumina furnace tube.

RFQ
What is the difference between ceramic and alumina?
Ceramics are non-metallic, inorganic materials that are typically composed of a combination of metallic and non-metallic elements. Alumina is a type of ceramic oxide, specifically an oxide of aluminum. It is widely used in various applications due to its excellent mechanical, thermal, and electrical properties.
What is alumina ceramic used for?
Everything You Need to Know about Alumina Ceramics
Because of their excellent chemical stability, alumina ceramics are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Aluminum oxide ceramics are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
