Zirconia (ZrO2) crucibles are excellent refractory and insulating containers. They melt cleanly at temperatures above 1900°C and are specifically designed for melting superalloys and precious metals. They also have excellent chemical inertness, excellent thermal shock resistance up to 2200°C, and good corrosion resistance to acids and bases.

Advantage of Zirconia
-High hardness, high toughness, high bending strength, the density of zirconia ceramics is between 5.95-6.05g/cm³, and zirconia has the highest toughness, above 8MPa•m1/2.
-High wear resistance, low friction coefficient, wear resistance is 15 times that of alumina ceramics, and the friction coefficient is only 1/2 of alumina ceramics. After grinding, the surface finish is higher, mirror-like, extremely smooth, and the friction coefficient is smaller.
-Good insulation, strong corrosion resistance, no static electricity, high-temperature resistance, Low thermal conductivity, excellent thermal insulation performance, and thermal expansion coefficient close to steel.
-Zirconium oxide ceramics have self-lubricating properties, which can solve the pollution and inconvenience of adding lubricating media.
-Chemically inert
-Resistant to molten metals
Application of zirconia crucible



Zirconia crucibles have very good resistance to chemical attack and thermal shock. Zirconia crucibles are ideal for melting gold, glass, metalworking/melting glass, rapid thermal cycles, gemstone purification for the jewelry industry, etc.
-Chemical calcining
-Metal casting
-Metal melting, especially in the superalloy and precious metal industries
-Thermal analysis crucibles
Packing
Our Zirconia crucibles are carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
