New developments in the classification and application of special ceramics

What are the types of special ceramics? What are the new developments in the application of special ceramics? The following will be introduced by Pintejin ceramic manufacturers.

Special alumina ceramic plate 1. Classification of special ceramics: According to their application functions, special ceramics can be roughly divided into two categories: high-strength, high-temperature resistant and composite structural ceramics and electrical and electronic functional ceramics. Inorganic materials with special formula are added to the ceramic blanks, which are sintered at a high temperature of about 1360 degrees to obtain stable and reliable anti-static properties and become a new type of special ceramics, which usually have one or more functions, such as: electricity, magnetism, Optical, thermal, acoustic, chemical, biological and other functions; and coupling functions, such as piezoelectric, pyroelectric, electro-optical, acousto-optical, magneto-optical and other functions.

They can be roughly divided into two categories: high-strength, high-temperature-resistant and composite structural ceramics and electrical and electronic functional ceramics. Specially formulated inorganic materials are added to the ceramic blanks, which are sintered at about 1360 degrees. To obtain stable and reliable antistatic properties, it becomes a new type of special ceramics, usually with one or more functions. Such as: electricity, magnetism, light, heat, sound, chemistry, biology and other functions, as well as coupling functions. Such as piezoelectric, pyroelectric, electro-optic, acousto-optic, magneto-optic and other functions.

Special zirconia ceramic cutter Special ceramics are divided according to chemical composition:

• ①Oxide ceramics: alumina, zirconia, magnesia, calcium oxide, beryllium oxide, zinc oxide, yttrium oxide, titanium dioxide, thorium dioxide, uranium trioxide, etc. .
• Nitride ceramics: silicon nitride, aluminum nitride, boron nitride, uranium nitride, etc.
• Carbide ceramics: silicon carbide, boron carbide, uranium carbide, etc. 
• Boride ceramics: zirconium boride, lanthanum boride, etc.
• Silicide ceramics: molybdenum disilicide, etc.
• Fluoride ceramics: magnesium fluoride, calcium fluoride, lanthanum trifluoride, etc. Sulfide ceramics: zinc sulfide, cerium sulfide, etc.

There are also arsenide ceramics, selenide ceramics, telluride ceramics, etc. New developments in the application of special ceramics: Special ceramics are widely used due to their many excellent properties. Now briefly describe the properties and types of materials.

• Special ceramics with excellent heat resistance are expected to be used as ultra-high temperature materials for high temperature structural materials and high temperature electrode materials related to atomic energy.
• Special ceramics with excellent thermal insulation properties can be used as new high-temperature thermal insulation materials for high-temperature heating furnaces, heat treatment furnaces, high-temperature reaction vessels, nuclear reactors, etc.
• Special ceramics with excellent thermal conductivity are very promising to be used as heat sinks for large-scale integrated circuits and ultra-large-scale integrated circuit electronic devices.
• The hard special ceramics with excellent wear resistance are widely used, and the current work is mainly concentrated on bearings and cutting tools.
• High-strength ceramics can be used in combustors, blades, turbines, casings, etc. of gas turbines; in machining machinery, they can be used in machine bodies, bearings, combustion nozzles, etc.At present, there is a lot of work in this area, and many countries, such as the United States, Japan, and Germany, have invested a lot of manpower and material resources to try to gain a leading position. Such ceramics include silicon nitride, silicon carbide, sialon, aluminum nitride, zirconia, etc.
• Ceramics with lubricating properties such as hexagonal boron nitride are extremely eye-catching, and are currently being studied abroad.
• In the aspect of bioceramics, the research on the use of alumina, phospho-carbon, etc. as artificial teeth, artificial bones, artificial joints, etc. is currently underway, and the application in this area has attracted great attention.
