Oxide Ceramics

Oxide ceramics are ceramic materials made of one or more oxides. Its atoms are mainly bonded by ionic bonds, and there are covalent bond components. Most simple metal oxide structures can be based on oxygen ions as a close-packed It is formed on the surface, and the metal cations are arranged in the appropriate gaps, which gives the oxide ceramics the advantages of higher melting point, good electrical insulation, excellent oxidation resistance and chemical stability.

The atomic bonds of oxide ceramic materials are mainly ionic bonds and some covalent bonds exist, so they have many excellent properties. Most oxides have high melting points, good electrical insulation properties, especially excellent chemical stability and oxidation resistance, and have been widely used in the upstream field.

There are many varieties of oxide ceramics with extremely wide uses. They can be used as structural materials, functional materials and advanced refractory materials in many fields such as computers, aerospace, chemical industry, metallurgy and so on. Oxide ceramics can be divided into single oxide ceramics and composite oxide ceramics according to their composition.

Oxide and composite oxide ceramic materials have the characteristics of high hardness, high melting point, good thermal stability and chemical stability. When used as coatings, they can effectively improve the wear resistance, high temperature resistance, high temperature oxidation resistance, and heat resistance of the base material. Impact, corrosion resistance and other properties. Therefore, when choosing the right materials, some of the superior properties of these properties can also be obtained by appropriately selecting coatings with oxides and composite oxides as the main components.
