Calcium Stabilized High Purity Zirconia Crucible

Calcium Stabilized High Purity Zirconia Crucible is made from high-purity zirconia (ZrO₂) as the main raw material, with the addition of an appropriate amount of calcium oxide (CaO) for stabilization. It is manufactured through advanced forming technology and high-temperature sintering.

The main components are ZrO₂ + HfO₂ ≥ 95.21%, with a calcium oxide (CaO) content of approximately 3.85%. It exhibits excellent high-temperature stability, thermal shock resistance, and chemical inertness. The crucible density reaches 4.1 g/cm³, and the maximum operating temperature can reach 2000℃. It is suitable for ultra-high temperature smelting, precious metal analysis, advanced materials research and development, and special industrial high-temperature applications.

Compared to ordinary zirconia, calcium stabilized zirconia crucibles have better phase stability and thermal cycling performance, effectively reducing the risk of cracking due to crystal form changes during high-temperature use. It is an ideal refractory container for demanding high-temperature experiments and industrial applications.
