Alumina ceramic crucible holder:

The crucible holder is a component used to hold crucibles and other utensils, and it needs to have sufficient heat resistance like the crucible. Our common crucible supports include metal and ceramics. Ceramics have the characteristics of high temperature resistance and oxidation resistance. Therefore, more and more people choose to be crucible holders. We provide users with corresponding alumina crucible holders. We can accurately manufacture various types of alumina crucible holders and crucible products according to the drawings provided by customers.

Ceramic Encyclopedia:

Ceramic crucibles have different degrees of heat resistance depending on the material. Generally, ceramic crucibles can reach a high temperature of up to 1200 degrees. It is mainly suitable for acidic molten samples such as potassium pyrosulfate. Alkaline substances such as sodium hydroxide, sodium peroxide, and sodium carbonate will cause the ceramic crucible to be corroded. Also note that the ceramic crucible cannot be in contact with HF (hydrofluoric acid). In addition, the cleaning of ceramic crucibles can generally be handled by boiling dilute hydrochloric acid. There are many types of ceramic crucibles, roughly including low-wall crucibles, middle-wall crucibles, infrared carbon-sulfur crucibles, volatile crucibles, high-wall crucibles, Roca crucibles, plain crucibles, strictly dense crucibles, double-layer crucibles, ancient crucibles, and fine crucibles. Hole crucible, free expansion coefficient crucible, etc. When using a ceramic crucible, pay attention to fully dry the crucible before use, and then place it on the analytical balance for weighing, otherwise the quality will be inaccurate.
