zirconia ceramic
1. Introduction:
Round Zirconia ceramic ring is used for a Ever Bright pad printing ink cup machine, electronic control, lighting and electrical temperature control and other industries.Zirconia ceramic ring tube is also used for thermostat,technical ceramic,temperature control. The temperature controllers,manufactured with Zirconia,have revolutionary breakthrough if compared with traditional plastic parts.They are highly improved in strength,insulation performance,heat resistant performance,especially sensitivity to temperature、
Meetcera is offered Yttria Tetragonal Zirconia Polycrystal(Y-TZP), there are many applications of Zirconia ceramics in the chemical and petrochemical industries. They provide economic payback in the way of reduced maintenance and down time. Zirconia ceramics is also becoming the material of choice for components in healthcare applications.
2. Zirconia ceramic ring features:
1). High temperature resisting
2). High density
3). High bending strength and breaking tenacity
4). Low thermal conductivity( 20% that of alumina)
4). Low thermal conductivity( 20% that of alumina)
5). Chemical inertness
6). Resistance to molten metals
7). Wear resistance
8).High fracture toughness
9). High hardness
