Corundum crucible is widely used for the melting and testing in laboratory . It mainly used for the dental porcelain furnace zirconia sintering.
Zirconia (ZrO2) can withstand the high temperature up to1800C and has very good resistance to chemical erosions and thermal shock. Zirconia crucible is ideal for the melting of precious metals and super-alloys. Zirconia crucibles are available in many sizes and shapes. Inert gas or high vacuum condition, they can remain good chemical resistance under high temperature and have excellent wear and abrasion resistance.
