The Most Potential 7 Big Oxide Ceramic Materials! Yu Shun Sand Mill To Create Professional Material Grinding Solutions

Oxide ceramics are structural materials composed of oxides, usually including alumina, zirconia, magnesium oxide, mullite, etc., which are sintered at high temperatures. Oxide ceramics as structural materials have high hardness, high strength, low density, high temperature and corrosion resistance and other excellent properties, usually used in the production of refractory materials, heat insulation materials, melting metal or alloy crucible and related containers, widely used in engine turbine blades, high temperature fasteners, aerospace materials, medical and other fields.

 With the improvement of technological level, the market competitiveness of Chinese enterprises is also increasing year by year, and some enterprises have reached the international leading level of technology. From the perspective of application fields, the rapid development of automotive, aerospace and other application fields provides a broad market space for the oxide ceramic industry. At present, China's oxide ceramic industry shows a trend of continuous growth.

Oxide ceramics according to different raw materials, can be divided into alumina ceramics, zirconia ceramics, magnesium oxide ceramics, beryllium oxide ceramics, tin oxide ceramics, silica ceramics, mullite ceramics, among which the most commonly used alumina ceramics and zirconia ceramics.

Alumina porcelain has high mechanical strength, high volume resistivity, good electrical insulation performance, high strength, wear resistance, oxidation resistance and other characteristics, is widely used as structural components and functional device porcelain, such as mechanical, chemical fields used in wear and corrosion resistance components; Crucible, protective tube, refractory material; Substrates, insulators, radomes, microwave electrolytes and other porcelain parts for electronic industry. Alumina ceramics is one of the advanced ceramics studied earlier, widely used and mature.

Zirconia ceramics is a newly developed second only to alumina ceramics a very important ceramic material, with high melting point, hardness, strength and toughness, low specific heat capacity and thermal conductivity, can form oxygen vacancy defect solid solution and other characteristics, is widely used as structural ceramics and functional ceramics, such as tools, mechanical parts, advanced refractories, high temperature anionic conductors, oxygen sensors and so on. However, a major disadvantage of zirconia ceramics is that its strength and toughness are severely attenuated at high temperatures, which limits its application at high temperatures.

Magnesium oxide ceramics is a kind of material with magnesium oxide as the main body, which is used in thick film integrated circuits. Magnesia ceramics have good conductivity, mechanical strength and high temperature resistance.

Beryllium oxide ceramics are ceramics with beryllium oxide as the main component. It is mainly used as large-scale integrated circuit board, high-power gas laser tube, heat sink shell of transistor, microwave output window and neutron moderator.

The thermal expansion coefficient is small, the thermal conductivity is high, and the thermal stability is higher than that of alumina ceramics and zirconia ceramics. Tin oxide ceramics can only be used in an oxygen atmosphere below 1500℃, strong resistance to the erosion of glass liquid, resistance to the erosion of lead glass, arsenic glass, iron glass, copper glass.

It has very excellent chemical stability, very low coefficient of thermal expansion, excellent thermal shock resistance, good transparency, high ultraviolet and infrared transmittance, good electrical insulation, and high temperature.

Mullite ceramics raw material purity is low, impurity content is high, so there is a considerable amount of glass phase in the product, resulting in its mechanical and thermal properties are poor, so that mullite ceramics at high temperature excellent performance can not be fully played. In industry, ordinary mullite ceramics can only be used as general refractory materials in occasions where the temperature and high temperature strength requirements are not high.
