Zirconia has excellent mechanical properties and higher strength and fracture toughness than alumina. It is also used for milling machines, sliding components, and cutting blades. Zirconia has good thermal insulation performance because its thermal conductivity is less than 1/10 of other ceramics.

When zirconia ceramics contain impurities, they are white, yellow, or gray and usually contain HfO2 that is difficult to separate. Pure ZrO2 exhibits three crystal states under atmospheric pressure. The production of zirconia ceramics requires the preparation of high-purity, good dispersion performance, ultrafine particles, narrow particle size distribution, zirconia ultrafine powder preparation methods, zirconia purification mainly includes chlorination and thermal decomposition, alkali metal oxidation decomposition, lime melting, plasma arc, precipitation, colloid, hydrolysis, spray pyrolysis, etc.

In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics due to their high toughness, high bending strength, high wear resistance, excellent insulation performance, and thermal expansion coefficient close to steel.

In terms of functional ceramics, their excellent high-temperature resistance is used as induction heating tubes, refractory materials, and heating elements. Zirconia ceramics have sensitive electrical performance parameters and are mainly used in oxygen sensors, solid oxide fuel cells (SOFCs), and high-temperature heating elements.

The zirconia bricks produced by our company have these excellent properties and have good application prospects in industry
