Advanced Zirconia Ceramic Components for High-Temperature Applications

Zirconia Ceramics

Zirconia Ceramic are made primarily from high-purity zirconium oxide (ZrO₂), typically monoclinic or partially stabilized zirconium oxide, through precision molding and high-temperature sintering. The products possess extremely high melting points, excellent chemical stability, low thermal conductivity, and good resistance to high-temperature corrosion, with a maximum operating temperature of up to 1900℃. Zirconia crucibles generally have a bulk density ≥5.0 g/cm³, a dense structure, and can be used for extended periods in high-temperature and highly corrosive environments.

제품특징

1. Ultra-high temperature performance, operating temperature up to 1900℃

The main chemical component is ZrO₂, with a bulk density generally above 5.0 g/cm³, and a maximum operating temperature of up to 1900℃. It has an extremely high melting point, making it suitable for long-term use in ultra-high temperature environments, and is one of the preferred refractory materials for extreme temperature conditions.

2. Excellent thermal stability and strong resistance to thermal shock

Made with monoclinic zirconium or partially magnesium-stabilized zirconium, the stabilization treatment effectively suppresses the volume effect caused by phase transformation. The low thermal conductivity helps reduce thermal shock temperature differences, making it less prone to cracking under rapid heating and cooling conditions, and adaptable to the demanding process requirements of frequent temperature increases and decreases.

3. Excellent chemical inertness and corrosion resistance

Excellent chemical stability, capable of long-term resistance to the corrosion of alkaline melts, acidic slags, and highly reactive metals (platinum, palladium, rhodium, and other precious metals). It has good resistance to penetration by most molten metals and slags, and does not easily react with furnace materials, ensuring product purity.

4. Excellent high-temperature creep resistance and no deformation

The structure is stable at high temperatures and exhibits excellent creep resistance, making it resistant to deformation even after long-term use. Suitable for precision melting and heat treatment processes where strict dimensional accuracy of the crucible is required.
