Longyou Shuochun New Material Technology Co., Ltd. will guide you to understand high-performance special ceramics.

High-performance special ceramics are a class of high-performance ceramic materials made from high-purity artificially synthesized inorganic compounds through precise sintering processes. The following provides a detailed introduction from six aspects: definition, classification, performance characteristics, application fields, forming processes, and development trends:

I. Definition High-performance special ceramics break through the limitations of traditional ceramics, which primarily use clay as a raw material. They mainly use oxides, carbides, nitrides, silicides, etc., and sometimes can be combined with metals to form ceramic-metal composite materials. They are prepared using modern materials science processes and possess unique and superior properties.

II. Classification Based on performance and material characteristics, high-performance special ceramics can be broadly classified into the following categories:

Structural ceramics: Possessing high strength, high hardness, high temperature resistance, corrosion resistance, and oxidation resistance, suitable for harsh environments or engineering applications.

Functional ceramics: Exhibiting many excellent properties in electrical, magnetic, acoustic, optical, and thermal aspects, such as piezoelectric, photoelectric, electro-optic, acousto-optic, and magneto-optic properties.

Semiconductor ceramics: Possessing semiconductor properties, suitable for the manufacture of electronic devices.

Ceramic fiber reinforced ceramic matrix composites: These composites enhance the ceramic matrix with ceramic fibers, improving the material's toughness and impact resistance.

Cereceramics: Composed of ceramic and metallic phases, they combine the advantages of both ceramics and metals.

III. Performance Characteristics
High-performance special ceramics possess the following significant performance characteristics:

High strength and high hardness: Capable of withstanding large loads and friction, suitable for manufacturing wear-resistant and cut-resistant parts.

High temperature and corrosion resistance: Maintains stable performance even in high-temperature and corrosive environments, suitable for high-temperature structural materials and chemical equipment.

Oxidation and acid/alkali resistance: Resistant to oxidation and acid/alkali corrosion, extending the material's service life.

Excellent thermal conductivity and insulation properties: Depending on the chemical composition, they can be used as heat sinks or high-temperature insulating materials.

Multiple functions: Possessing practical functions such as electromagnetic, chemical, and semiconductor kinetic energy capabilities, and these functions can be adjusted according to requirements.
