Application prospects of high-performance
ceramic materials: High-performance ceramics are an integral part of new
materials, and they are widely used in energy, electronics, aerospace,
machinery, automobiles, metallurgy, petrochemical and biological aspects of the
national economy. In the future, it has become an indispensable key material in
various industrial technologies, especially cutting-edge technologies. In the
modernization of national defense, the development of weapons and equipment is
also inseparable from special ceramic materials. With the rapid development of
the national economy, the continuous improvement of industrial technology, the
continuous improvement of people's lives and the needs of national defense
modernization, there is an urgent need for a large number of special ceramic
products, and the market prospect is very broad. The petrochemical industry
requires a large number of wear-resistant and corrosion-resistant ceramic
components, such as ball valves, cylinder liners, etc. The textile industry needs
a large number of wear-resistant ceramic parts, such as ceramic scissors, godet
wheels, etc. Ceramic materials with special properties required by the national
defense industry, such as bulletproof armor ceramics, high-temperature
light-resistant heat-insulating materials, ceramic materials for aerospace
mirrors, ceramic materials for concentrators for lasers, infrared absorption,
and infrared emission.
High-performance ceramics are generally
divided into structural ceramics and functional ceramics, and some are also
divided into ceramic coatings and ceramic composite materials. Structural
ceramics are mainly used in thermomechanical parts and wear-resistant parts,
such as heat exchangers such as knives, bearings, sealing rings, valves,
bulletproof materials, and bioceramics, by virtue of their high temperature
resistance, high strength, and wear resistance. The main materials are Si3 N4, SiC, ZrO2, Al2 O3, SiALON, etc.
