Application of Special Ceramic Materials in Environmental Materials

The application of special ceramics in the environment is mainly concentrated in the engine field of automobiles and airplanes. New ceramic based materials can improve fuel utilization and oil transportation, which invisibly protects the environment.

Special ceramics mainly include zirconia, alumina, and silicon carbide ceramics; There are various forming methods such as hot press casting, hot pressing, static pressure, and vapor deposition. These ceramics are called special ceramics or high-tech ceramics due to their different chemical composition, microstructure, and properties from ordinary ceramics, and are referred to as fine ceramics in Japan. The different chemical composition and organizational structure of special ceramics determine their different special properties and functions, such as high strength, high hardness, high toughness, corrosion resistance, conductivity, insulation, magnetism, transparency, semiconductors, as well as piezoelectric, optoelectronic, electro-optic, acoustooptic, magneto-optical, etc. Due to their special properties, such ceramics can be used as engineering structural materials and functional materials in machinery, electronics, chemical industry, smelting, energy, medicine, laser, Nuclear reaction, aerospace, etc. Some economically developed countries, especially Japan, the United States, and Western European countries, have invested a large amount of manpower, material resources, and financial resources to research and develop special ceramics in order to accelerate the new technological revolution and lay a material foundation for the development of new industries. Therefore, the development of special ceramics has been very rapid, and there have been significant technological breakthroughs. The position of special ceramics in modern industrial technology, especially in high-tech and new technology fields, is becoming increasingly important.

Special ceramics zirconia ceramics and alumina ceramics have excellent mechanical properties at room temperature, such as high Flexural strength, excellent oxidation resistance, good corrosion resistance, and high abrasion resistance. The material sintered by isostatic pressing can maintain its high-temperature strength up to 1600 ℃, making it a material with excellent high-temperature strength among ceramic materials. The oxidation resistance is also very good among all non oxide ceramics. In recent years, special ceramics such as zirconia and alumina ceramics have improved the toughness and strength of monomer materials. Special ceramics have been widely used in industries such as petroleum, chemical, microelectronics, automotive, aerospace, aviation, papermaking, laser, mining, and atomic energy.
