Ultra-fine yttrium-stabilized zirconia
Basic information:
:
Properties:
Ultra-fine yttrium-stabilized zirconia is a new type of ceramic material with excellent mechanical properties and applications. widely. During the pure cooling process from high temperature to room temperature, the following phase transformation will occur: cubic phase () rr tetragonal phase rrr monoclinic phase. Ultrafine yttrium-stabilized zirconia ( ) has the characteristics of high temperature resistance, chemical corrosion resistance, oxidation resistance, wear resistance, large thermal expansion coefficient, small heat capacity and thermal conductivity, etc., therefore it is an ideal high-temperature refractory material and special Ceramic materials, abrasive materials and high temperature insulation materials.
Ceramics sintered from ultrafine yttrium-stabilized zirconia powder have become one of the main structural ceramics due to their good phase change toughening properties. Ultrafine yttrium-stabilized zirconia has been widely used as an ideal electrolyte. Used in solid oxide fuel cells. Stable ultra-fine zirconium dioxide powder has the characteristics of good dispersion, fine particle size, narrow particle size distribution, and low cost. Ultra-fine powder with narrow particle size distribution can help reduce the firing temperature of ceramics and improve the microscopic properties of ceramics. structure, thereby improving the electrical properties of ceramics, which can fully meet society's development needs for refractory materials and special ceramic materials.
