Explanation

It is also called high performance ceramics, technical ceramics, new ceramics, high technology ceramics, engineering ceramics, fine ceramics and moden ceramics. Generally, ceramics materials with specific properties are made from refined high-purity, ultra-fine synthetic inorganic compounds through composition and structure design, using new preparation technologies of precise stoichiometry and precise control. Their properties are not only far superior to traditional ceramics, but also have many new physical chemistry properties that traditional ceramics do not have. Different from traditional ceramics or industrial ceramics, it broadly includes artificial single crystal, amorphous, ceramics and their composite materials, semiconductors, refractory and cement. It can be divided into three categories according to functions and uses: ① functional ceramics (also called electronic ceramics), which refers to the use of their electrical, magnetic, acoustic, optical, thermal, elastic, chemical and other properties or their coupling effects to achieve a certain use function, mainly for civil use, but also for high-tech and military technology. Such as underwater sound, optoelectronics, infrared technology, etc.; ② structural ceramics (also known as engineering ceramics), which are used for various structural parts to play their mechanical, thermal, chemical and other functions, are mainly used for parts that require high temperature resistance, corrosion resistance and wear resistance, such as mechanical seals, ceramics bearings, ball valves, cylinder liners, aircraft radomes, etc.; ③ Biological cemmics, which play their biological and chemical functions, are mainly used for artificial bones, artificial joint, immobilized enzyme carriers, catalysts, etc., and have good biocompatibility and chemical stability.
