Super wear resistant ZTA ceramic liner ZTA ceramic liner(Zirconium aluminum composite) is made of high purity powder ZrO2 & Al203 with serevals rare element as raw material through high pressure moulding and high temperature sintering techincal process. It has excellent hardness and toughness. As the ZTA ceramic’s life span is 2.5 times longer that alumina ceramic liner, it is widely used in these equipments of chute,hopper etc, especially applicated in condition when it happens large feed transportation,the high impact, the poor production environment,the high wear rate of mine ,port industries etc. PINGXIANG CHEMSHUN CERAMICS CO.,LTD is a professional manufacturer of wear resistant ceramic & ceramic grinding media.our Rubber ceramic wear liner vulcanized with ZTA ceramics has less than 0.01cm3 wear volume, its density is about 4.1g/cm3, the rockwell hardness can be up to…

Types and properties of ZTA ceramic bar metallization

Blog
Types and properties of ZTA ceramic bar metallization Zirconia ceramic bar is manufactured by isostatic pressure process, forming uniform, compact and smooth ceramic layer and transition layer under high temperature and high speed. Because of advanced production technology, high cost, suitable for precision ceramic parts, and its wear resistance than other ceramic bars, generally used as a high-wear site. Zirconia ceramic bar metallization is to use high temperature resistant strong adhesive to paste the ceramic bar on the inner wall of the metal. The production process of this product is relatively simple, the production cycle is short and the cost is relatively low. Technical specification: mingrui ceramics has ceramic bars of various sizes, and can be customized according to customer needs. Metallized ceramic bars are basically free from size limits, with diameters…

Toughening mechanism of zirconia toughened alumina ceramics

Toughening mechanism of zirconia toughened alumina ceramics

Blog
Toughening mechanism of zirconia toughened alumina ceramics Zirconia toughening alumina ceramics also called ZTA ceramics , is produced by adding to or being into the ceramic particles, whiskers, fibers and other reinforcing materials, so that the toughness of the ceramic greatly improved, but also have some strength and modulus increased. At present most applied toughening method is by adding zirconia . The toughening of zirconia-toughened alumina ceramics incorporates a number of toughening mechanisms: (1) Phase change toughening: the use of tetragonal ZrO2 martensitic transformation to change the toughness of ceramic materials. When the ceramic is subjected to external stress, the tetragonal phase particles will transform into allotrope monoclinic ZrO2, meanwhile, the volumetric expansion will be 3% -5%, absorbing the strain energy and bridging the crack, so as to improve the…
