Information on toughened zirconia ceramics

The toughened zirconia ceramic material is white, and the material of the product forms an excellent composite with high strength and toughness, making it more widely used. For non professionals who are not very familiar with this product, the manufacturer will provide you with some information about the product below.

Toughened zirconia ceramics have a melting point of 1700 ℃ and a Mohs scale hardness of 9. There are two variants, of which the product has low thermal conductivity, large coefficient of linear expansion, high high temperature structural strength and negative resistance temperature coefficient. one

The Monoclinic crystal system (density 5.68g/cm3) is formed below 1000 ℃, and the Tetragonal crystal system (density 6.10g/cm3) is formed at 1000 ℃. The transformation of this crystal form is reversible, accompanied by 7% volume expansion during the cooling process, which can lead to product cracking.

At the same time, it has no effect on various molten metals, silicates, glass, etc. below 2000 ℃.

Caustic alkali and carbonate solutions have no effect on toughened zirconia ceramics.

Toughened zirconia ceramics can adjust the specific ratio of the two materials according to the actual usage requirements of users. The performance of this product is superior to that of 99 alumina ceramics, and the price is much lower than that of 99 alumina ceramics. Many situations where alumina ceramics are not competent reflect the superior cost-effectiveness of toughened zirconia ceramics.
