Zirconium Oxide Special-Shaped Ceramic Special-Shaped Structural Parts
Product Overview
Witt Ceramics is a professional manufacturer of zirconia shaped ceramics. In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics due to their advantages of high toughness, high flexural strength and high wear resistance, excellent thermal insulation performance, and thermal expansion coefficient close to that of steel. Mainly include: Y-TZP grinding balls, dispersing and grinding media, nozzles, ball valve ball seats, zirconia molds, miniature fan shafts, fiber optic pins, fiber optic sleeves, drawing dies and cutting tools, wear-resistant knives, watch cases and Watch straps, light golf bats and other room temperature wear-resistant zero devices.
Zirconium oxide is also resistant to the erosion of molten metal, so it is often used as a smelting crucible for metals such as platinum and heat generators above 1800 °C, furnaces, 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 is 1200MPa, and the fracture toughness is 15.0, which is three times and nearly three times higher than the original alumina, respectively. Its kang corrosivity can be used to line the ladle of the ladle and to be the gate brick in continuous cast steel. Zirconium oxide can be used to manufacture engine components due to its high strength and excellent toughness (compression strength at room temperature can reach 2100 MPa, 1190 MPa at 1000 °C, flexural strength of toughened ceramic at room temperature can reach up to 2000 MPa).
