Porous alumina ceramic structural parts

Porous alumina ceramic structure is a kind of material with excellent properties such as high strength, good insulation, high temperature resistance and corrosion resistance.
Porous alumina ceramic structural parts are mainly made of high-purity alumina powder, and their unique porous structure endows this material with many special properties. These structural parts occupy an important position in the frontier fields of electronics, aerospace, medical treatment, etc., and are widely used in various industrial and scientific research due to their superior properties.

Material composition:
Alumina powder: core raw material with different purity and performance. 95% alumina powder is cost-effective and has good overall performance; 99% alumina powder improves electrical insulation and mechanical strength; 99.9% and above ultra-high purity alumina powder shows high-end characteristics and is suitable for extreme environments and high-precision applications.
Flux and additives: such as titanium dioxide (TiO), yttrium oxide (YO), cerium oxide, lanthanum oxide, etc. These additives can optimize the internal structure of materials, enhance hardness and toughness, and give them unique electrical and optical properties.

Performance features:
High strength: The hardness of alumina ceramic materials is very high, with a Mohs hardness of 9, much higher than that of metal materials, which makes them highly resistant to deformation when subjected to high pressure and impact forces.
Good insulation: its resistivity can reach 10 ^ 14 cm, much higher than that of metal materials, and it is suitable for electronics, electrical and other fields.
High temperature resistance: Alumina ceramic materials have a melting point of up to 2050 ° C, a low coefficient of thermal expansion, and good thermal shock resistance, making them suitable for high-temperature environments.
Corrosion resistance: It has good corrosion resistance to most acids, alkalis, salts and other chemical media, and is suitable for chemical, petroleum and other fields.
Biocompatibility: non-toxic and non-irritating to the human body, and can be used in biomedical fields such as the production of medical apparatus.

Application field:
Electronic equipment substrate: Due to its excellent insulation properties, high temperature resistance and corrosion resistance, it is widely used in the fabrication of electronic equipment substrates.
Aerospace: In the combustion chamber lining of aerospace engines, it can withstand high temperature gas shock.
Medical field: used to make artificial joints, because of its good biocompatibility, reducing the risk of human rejection.
Chemical and petroleum fields: used to make strong structural parts that are resistant to acid and alkali, such as pipes, valves, pumps, etc.

Porous alumina ceramic structures play an important role in many high-tech fields and industrial applications due to their unique porous structure and excellent properties.
