Magnesium oxide stabilizes zirconia

  • Finished product characteristics

    ● Very high heat resistance temperature (2000℃) ● Good thermal shock stability ● High mechanical properties ● High hardness, high toughness, high bending strength ● High wear resistance, low friction coefficient ● Strong corrosion resistance ● Good insulation, no static electricity

  • Product characteristics

    Cubic zirconia and metastable tetragonal zirconia ceramics can be prepared by using magnesia as stabilizer according to the different content of magnesia and the difference of manufacturing technology. By controlling the growth of tetragonal nuclei, the stable zirconia ceramics with the best bending strength and fracture toughness can be obtained.

  • Precision machining

    1. 3Y, 5Y, 8Ymol yttrium stabilized zirconia zirconia powder

    2. Open mold processing: dry pressing, CIM injection molding, isostatic pressing.

    3. Appearance processing: surface grinding, outer diameter/inner diameter grinding, fine engraving machining, grinding, polishing grinding.

  • Application field

    ● Metallurgy ● Steel ● Petrochemical industry ● Electronic components ● Power ● Machinery textile industry special ceramic cutting tools, standard measuring tools, mechanical sealing, stamping die and all kinds of wear-resistant parts and other fields.
