Zirconia Ceramic (ZrO2)

Zirconia oxide 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.

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 alumina parts as per customer’s process requirement, or recommend the most cost-effective process.
