Zirconia Ceramic (ZrO2)
Zirconia ceramic has the highest strength and toughness when compared with other advanced ceramic materials, prices are higher as well. The fine grain size allows for extremely smooth surfaces and sharp edges. We manufacture custom zirconia ceramics like zirconia rod, zirconia tube, and so on.
The advantages of
zirconia ceramic:
– Electrical insulation
– Mechanical strength
– Low density
– Tracking resistance
– Resistance to high temperatures
– Resistance to thermal shock
– Wear resistance and hardness
– Resistance to climate and ageing
– Environmentally compatible disposal
– Chemical resistance
– Food safe
The application of
zirconia ceramic:
Typical applications include scissors, knifes, slitters, pump shafts,
metal-forming tools, fixtures, tweezers, wire drawing rings, bearing sleeves
and valves.
The manufacturing
process of zirconia ceramic:
Ningbo Victor Import And Export Co., Ltd can manufacture zirconia ceramic via four
different process, include dry pressing, injection moulding, isostatic pressing
and extruding. We will manufacture the zirconia ceramic parts as per customers' requirement, or recommend the most cost-effective process.
