Classification of ceramic materials and its definition
Ceramic materials due to its excellent wear resistance, corrosion resistance, high temperature resistance, low density and other properties, is recognized as one of the 21st century is very dynamic new materials, then the United States ceramic to introduce the classification of ceramic materials and its definition.
By summarizing the characteristics and application fields of various ceramics, the future development of ceramic materials is prospected, and the application direction and development trend of ceramic materials are revealed.
Functional ceramics refer to materials whose non-mechanical properties are mainly used in their application. Such materials usually have one or more functions, such as electrical, magnetic, optical, thermal, chemical, biological, etc. And coupling functions, such as piezoelectric, magnetic, thermoelectric, electro-optic, acoustooptic, magneto-optical and other functions. Functional ceramics have been widely used in energy development, space technology, laser technology, optoelectronics technology, infrared technology, biotechnology, environmental science and other fields.
Traditional ceramic materials mainly refer to silicon aluminate. At the beginning, people did not have high requirements for the selection of silicon aluminate, the purity was not large, the particle size was not uniform, and the forming pressure was not high. At this time, the ceramics are called traditional ceramics.
Later developed to high purity, small particle size and uniform, forming high pressure, sintered body is called fine ceramics. The mechanical properties of ceramics are related to the chemical bond structure of ceramic materials. Any chemical substance that can form a strong three-dimensional network structure when forming crystals can be used as ceramic materials.
The theory of studying the structure and properties of ceramics has also been developed: the influence of internal microstructure (microcrystalline surface interaction, porous polyphase distribution) on mechanical properties of ceramic materials has been developed.
Material (optical, electric, thermal, magnetic) properties and forming relationships, as well as particle size distribution, bonding interface relationships have also been developed, ceramics should become a bearing certain properties of the material existence form. This should be related to quantum mechanics, surface chemistry, etc.
The above is the content of Meicheng ceramics for you.
