The concept of ceramics has gone far beyond the ancient traditional ceramics. Ceramic materials with high temperature resistance, corrosion resistance or various sensitive properties, due to their different manufacturing processes and traditional ceramics, more importantly, due to its chemical composition, microstructure and characteristics are different from traditional ceramics, so it is called New ceramics. New ceramics also have the following claims: advanced ceramics, high-performance ceramics, high-tech ceramics, fine ceramics, specialty ceramics, and industrial ceramics. Most of our country is called "industrial ceramics."
The new ceramics are artificial inorganic powder materials that achieve specific properties through structural design, precise stoichiometry, suitable molding methods and firing systems, and are processed and processed to meet the accuracy requirements of inorganic non-metallic materials.
New ceramics fall into two major categories, namely structural ceramics (or engineering ceramics) and functional ceramics. Ceramics that have mechanical, thermal, and partial chemical functions are listed as structural ceramics, and ceramics that have electrical, optical, magnetic, chemical, and biological properties and that have mutual conversion functions are classified as functional ceramics. New ceramics often have more than a single function, so it is difficult to exactly divide and classify them.
Functional ceramics have many functions such as electrical insulation, semiconductivity, conductivity, piezoelectricity, ferroelectricity, magnetism, corrosion resistance, chemical adsorption, biocompatibility, sound absorption, and radiation resistance, and have mutual conversion. The function.
With the development of science and technology, multi-functional ceramic materials have gradually been developed and produced. The versatility of this ceramic material is difficult to achieve with other materials, and it is very noticeable.
