The 7 most promising oxide ceramic materials! Sand mills create specialized material grinding solutions.

Oxide ceramics are structural materials composed of oxides, typically including alumina, zirconia, magnesia, mullite, and others, which are made through high-temperature sintering. As structural materials, oxide ceramics exhibit excellent properties such as high hardness, high strength, low density, high-temperature resistance, and corrosion resistance. They are commonly used to manufacture refractory materials, thermal insulation materials, metal or alloy crucibles and related containers, and have broad applications in fields such as engine turbine blades, medium- and high-temperature fasteners, aerospace materials, and medical industries.

With the improvement of technological levels, Chinese companies' market competitiveness has been increasing year by year, with some enterprises reaching internationally leading technological standards. From the perspective of application fields, industries such as automotive and aerospace are developing rapidly, providing a vast market space for the oxide ceramics industry. Currently, the Chinese oxide ceramics industry is showing a continuous growth trend. 

Classification of Oxide Ceramics

Oxide ceramics can be categorized based on their raw materials into alumina ceramics, zirconia ceramics, magnesia ceramics, beryllia ceramics, tin oxide ceramics, silica ceramics, and mullite ceramics. Among these, alumina ceramics and zirconia ceramics are the most commonly used.

Alumina Ceramics

Alumina ceramics possess high mechanical strength, high volume resistivity, excellent electrical insulation, high strength, wear resistance, and oxidation resistance. They are widely used as structural components and functional ceramic parts, such as wear- and corrosion-resistant components in mechanical and chemical industries; crucibles, protective tubes, and refractory materials; substrates, insulators, radar antenna covers, and microwave electrolytes in the electronics industry. Alumina ceramics are one of the earliest studied, most widely applied, and most mature advanced ceramics.

Zirconia Ceramics

Zirconia ceramics, a relatively new and important ceramic material second only to alumina ceramics, have high melting points, hardness, strength, and toughness, along with low specific heat and thermal conductivity. They can form oxygen vacancy defect solid solutions, making them widely used as structural and functional ceramics, including in cutting tools, mechanical components, high-grade refractory materials, high-temperature anion conductors, and oxygen sensors. However, their major drawback is the significant degradation of strength and toughness at high temperatures, limiting their applications in extreme heat conditions.

Magnesia Ceramics

Magnesia ceramics, primarily composed of magnesium oxide, are used in thick-film integrated circuits. They exhibit good conductivity, mechanical strength, and high-temperature resistance.

Beryllia Ceramics

Beryllia ceramics are mainly composed of beryllium oxide and are used in large-scale integrated circuit substrates, high-power gas laser tubes, transistor heat sinks, microwave output windows, and neutron moderators.

Tin Oxide Ceramics

Tin oxide ceramics have a low thermal expansion coefficient, high thermal conductivity, and better thermal stability than alumina and zirconia ceramics. They can only be used in an oxygen atmosphere below 1500°C and have strong resistance to glass corrosion, particularly against lead glass, arsenic glass, iron glass, and copper glass.

Silica Ceramics

Silica ceramics exhibit exceptional chemical stability, an extremely low thermal expansion coefficient, excellent thermal shock resistance, good transparency, high ultraviolet and infrared transmittance, and excellent electrical insulation. They also have a high operating temperature range.

Mullite Ceramics

Mullite ceramics contain a significant amount of glass phase due to the low purity and high impurity content of raw materials, leading to inferior mechanical and thermal properties. As a result, their excellent high-temperature performance cannot be fully utilized. In industrial applications, ordinary mullite ceramics are mainly used as general refractory materials in environments with moderate temperature and strength requirements.
