Alumina Crucible

Alumina Crucible 

Description of alumina crucible

Alumina crucible. The shape is mainly cylindrical, conical, square, etc. The alumina crucible has a high purity, containing over 99% AL2O3. 99% alumina material is used to make high-temperature crucibles, with good chemical corrosion resistance and temperature resistance. Alumina crucible can be used for a long time at 1650 ℃, and can also be used at temperatures up to 1800 ℃. But it can only be used for a short period of time.

Application of alumina crucible

Aluminum oxide crucibles are used for analyzing and melting various laboratory metal and non-metal samples, as well as firing pigments, colorants, glass materials, pigments, luminescent materials, etc. in shuttle kilns and push plate kilns. Aluminum oxide crucibles are used in small experimental kilns, experimental electric furnaces for adjusting formulas, and other purposes. Melting metals, precious metals, optical glasses, used for analyzing and firing mineral raw materials such as rare earths, as well as firing high-temperature products such as ceramic powders.

Advantages of alumina crucibles

1. Alumina crucible has good resistance to sudden heat and cold, and is not easy to explode.

2.The alumina crucible is formed by slip casting molding, so its density is high.

3.In oxidizing and reducing atmospheres, alumina crucibles have good high-temperature insulation and mechanical strength.

4.Alumina crucibles have high thermal conductivity and low thermal expansion rate.

FAQ

1.What is alumina crucible?

Crucibles are used in chemistry laboratories as containers for extremely hot chemical compounds and are made from materials with high-temperature resistance. The ceramic form of alumina is commonly used because of its low cost, strength, and ability to withstand temperatures as high as 3272°F (1800°C).

2.Is alumina crucible better than graphite?

Alumina crucibles have longer life span compared to clay graphite crucibles, and provide advantage especially for continuous working systems.

3.Can alumina crucibles be customized?

Yes.We accept customized alumina crucibles based on drawings.
