Description

Mullite-crucibles are one type of crucible made out of the refractory ceramic known as mullite, renowned for its high melting points and resistance to thermal shock as well as low thermal expansion rates.

Mullite crucibles are well-suited to high temperature applications for melting and casting alloys, metals and other materials at extreme temperatures. Their qualities have made them popular choices among laboratories, foundries and industrial settings where extreme temperatures are needed.

Mullite Crucibles are used extensively for melting precious metals such as gold, platinum and silver as well as conducting chemical reactions requiring high temperatures. Available in multiple sizes and shapes to meet various applications needs. Mullite crucibles tend to be durable and long-lasting.
