Product Description

1. Product Overview

The Zirconia Crucible is a high-performance refractory ceramic container made from high-purity zirconium dioxide (ZrO₂). It is manufactured through advanced processes such as isostatic pressing and high-temperature sintering, ensuring excellent density and structural stability. With an extremely high melting point of approximately 2700°C, zirconia crucibles are widely used in high-temperature applications where conventional materials such as alumina or quartz are not sufficient.
