Zirconia Crucible Description
High purity zirconia crucibles are great refractory and insulating containers. They can withstand a high temperature above 1900°C and above and are specially manufactured for melting superalloys and precious metals. They also have excellent chemical inertness, superior thermal shock resistance to temperatures reaching up to 2200°C, and good corrosion resistance to acids and alkalis.
