Zirconia ceramics containing impurities are white, yellow or grey, and usually contain HfO 2 which is not easy to separate. Pure ZrO2 has three crystalline states at atmospheric pressure. The production of zirconia ceramics requires the preparation of high purity, good dispersion properties, ultrafine particles, narrow particle size distribution, and preparation methods of zirconia ultrafine powder. Zirconia purification is mainly chlorination and thermal decomposition, alkali metal oxidation decomposition, lime melting method, plasma arc method, sedimentation method, colloidal method, hydrolysis method, spray heat. Solution and so on.
In structural ceramics, zirconia ceramics are widely used in structural ceramics because of their high toughness, high flexural strength and wear resistance, excellent thermal insulation and similar thermal expansion coefficient to steel. Main: Y-TZP grinding ball, dispersing and grinding medium, nozzle, ball valve seat, zirconia mould, micro fan shaft, fiber pin, fiber sleeve, wire drawing die and cutting tools, wear-resistant tools, buckles, case and strap, bracelet and pendant, ball bearing, Golf batter and other room temperature wear-resistant components.
As far as functional ceramics are concerned, their excellent high temperature resistance is used as induction heating tubes, refractories and heating elements. Zirconia ceramics have sensitive electrical properties, which are mainly used in oxygen sensors, solid oxide fuel cells (SOFC) and high temperature heaters. ZrO2 has a high refractive index (N-21 ^ 22). It can be made into color translucent polycrystalline ZrO2 by adding some coloring elements (V2O5, MoO3, Fe2O3, etc.) into ultrafine zirconia powder. Like natural gemstones, it can emit colorful light and can be made into various decorations. In addition, zirconia is widely used in thermal barrier coatings, catalyst carriers, medical, health care, refractories, textiles and so on.
High strength, high hardness, impact resistance, wear resistance, corrosion resistance, smooth surface, low thermal conductivity, non-magnetic, etc.
