Alumina Ceramic Tube In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics because of their high toughness, high flexural strength and high wear resistance, excellent thermal insulation properties, and thermal expansion coefficient close to steel. Mainly include: Y-TZP Mechanical Ceramic Parts grinding balls, dispersing and grinding media, nozzles, ball valve seats, zirconia molds, miniature fan shafts, fiber optic pins, fiber optic sleeves, wire drawing dies and cutting tools, wear-resistant knives, watch cases and Watch straps, light bats for golf balls Ceramic Part and other room temperature wear parts, etc.
Since zirconia can also resist the erosion of molten metals, it is mostly used as smelting crucibles for metals such as platinum, heating elements and furnaces above 1800 °C, and reactor insulation materials. In particular, zirconia as an additive can greatly improve the strength and toughness of ceramic materials. The strength of the zirconia toughened alumina ceramic material reaches 1200MPa and the fracture toughness is 15.0, which are three times and nearly three times higher than that of the original alumina, respectively. Its kang corrosiveness can be used as the lining of the ladle, and as a gate brick in continuous cast steel. Zirconia can be used to manufacture engine components due to its high strength and excellent toughness (compressive strength at room temperature can reach 2100MPa, 1190MPa at 1000 °C, and flexural strength at room temperature of toughened ceramics can reach up to 2000MPa).
