Product Description

Zirconia has a higher melting point than zirconium, reaching 2700°C. Crucibles made of zirconia materials can successfully melt platinum group precious metals such as platinum, palladium, ruthenium, cesium and their alloys. it is a special oxide refractory material that cannot be replaced by other oxide materials when used in high-temperature furnaces above 2000 °C.

Features:
1) Density is 6.05 g/cm3, denser than alumina crucible.
2) Better wear resistance. The wear resistance is equivalent to 266 times that of manganese steel, and the service life can be extended by more than 10 times
3) High toughness. Higher flexural strength, compressive strength
4) Better sharpness, suitable for making ceramic blades
