Special ceramics (wire feed roll)
Aluminum oxide ceramics, silicon nitride ceramics, zirconia ceramics
Special ceramics refer to ceramics with special mechanical, physical or chemical properties, which are used in various modern industries and cutting-edge science and technology. The raw materials used and the required production technology are quite different from ordinary ceramics and have developed. Some countries call it "precision ceramics". Recently, China's material experts agree that it is better to call it "advanced ceramics". Special ceramics can be subdivided into structural ceramics, functional ceramics and tool ceramics according to their performance characteristics and uses.
Special ceramics, also known as fine ceramics , are classified according to their application functions and can be roughly divided into two categories: high-strength, high-temperature-resistant and composite structural ceramics and electrical and electronic functional ceramics. Add specially formulated inorganic materials to ceramic blanks, and sinter them at a high temperature of 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, Functions of light, heat, sound, chemistry, and biology; and coupling functions, such as piezoelectric, pyroelectric, electro-optic, acousto-optic, magneto-optic, and other functions.
The future development trend of new materials is the miniaturization of functional materials, informatization, and compounding of structural materials. For special ceramic materials and their products, in addition to meeting the above-mentioned development direction, they must also meet the requirements of low cost in order to meet the needs of the market. Around the above-mentioned The general development trend of special ceramic materials has been greatly improved in the aspects of raw material preparation, manufacturing technology, material structure and performance relationship, testing and characterization.
With the rapid development of electronic information technology, functional ceramics with information technology as the application field has become a very active field in the research of new materials. And its application fields are shifting from traditional consumer electronics products to digital information products, including communication equipment, computers and digital audio and video equipment.
