How is Alumina Ceramic Crucible used?
Alumina Ceramic Crucible is mainly made of alumina. It is fired at high temperature with a special formula. It is a refractory with high fire resistance. It can withstand temperatures of 1800 degrees Celsius and high temperature resistance. It is usually used for smelting precious metals, nickel And other metals, with excellent chemical resistance and high temperature resistance.
Friends who are familiar with alumina crucibles know that Alumina Ceramic Crucible has certain conditions when using it, such as the proportion of corundum and temperature. Today we will share with you the use of Alumina Ceramic Crucible
Crucibles have good high temperature insulation and mechanical strength in an oxidizing and reducing atmosphere. Large thermal conductivity and low thermal expansion. Does not react with air, water vapor, hydrogen, carbon monoxide, etc. above 1700 ° C. The short-term maximum use temperature is 1800 ℃. High aluminum crucibles have good high temperature insulation and mechanical strength in an oxidizing and reducing atmosphere. Large thermal conductivity and low thermal expansion. Does not react with air, water vapor, hydrogen, carbon monoxide, etc. It can be used for a long time without changing the temperature in the temperature field. The short-term maximum use temperature is 1400 ° C.
