Zirconium Oxide Ceramics

Zirconia is an important class of ceramic materials as advanced ceramics, and is a very important basic material for the development of modern high-tech industry. Zirconia ceramics, with high melting point and boiling point, high hardness, excellent wear resistance, as an insulator at room temperature, and high temperature has excellent properties such as electrical conductivity.Zirconia ceramics are involved in a wide range of fields and occupy most of our lives. Service areas include: 5G communication, petrochemical, medical equipment, photovoltaic industry, aerospace, military equipment, semiconductors, electronic appliances, pumps, valves, lithium batteries, etc.


Properties and characteristics of zirconia ceramics

Zirconia ceramics is a new type of high-tech ceramics, it in addition to high strength, hardness, high temperature resistance, acid and alkali corrosion resistance and high chemical stability and other conditions, at the same time with scratch resistance and wear resistance, no signal shielding, excellent heat dissipation performance and other characteristics, while strong machinability, good appearance effect.


1, high melting point, high melting point and chemical inertness make zirconia can be used as a better refractory;

2, with greater hardness and better wear resistance;

3, the strength and toughness are relatively large;

4, low thermal conductivity, low expansion coefficient, suitable for structural ceramic materials;

5, good electrical performance, from the shielding efficiency point of view, zirconia ceramic as a non-metallic material has no shielding effect on electromagnetic signals, will not affect the internal antenna layout.
