Zirconia powder for sale

ジルコニア, also known as ZrO2, is an inorganic non-metallic material that is resistant to high temperatures, 腐食, and wear, and has excellent electrical conductivity. In addition to its traditional applications in refractory materials and ceramic pigments, ZrO2 is also used in high-tech fields such as electronic ceramics, 機能性セラミックス, および構造セラミック.

Zirconia powder introduction

ジルコニアパウダー (ZrO₂) is a functional ceramic material with high melting point, 高強度, high toughness, and excellent chemical stability.

As one of the most important basic raw materials for advanced ceramics, zirconium oxide is widely used in high-end fields such as structural ceramics, oxygen sensors, 燃料電池, electrode coatings, and optical coatings due to its excellent mechanical properties and ionic conductivity. Zirconia powder is a white to light gray powder that can exist in monoclinic, tetragonal, or cubic crystal structures.

With a melting point as high as 2715°C, and possessing both hardness and strength, it is known as “ceramic steel.”

It is prepared using chemical co-precipitation or hydrolysis methods, resulting in powders with high purity and excellent dispersibility.
