Industrial Ceramic Technology
Industrial ceramics refers to all ceramic materials, excluding daily-use ceramics, decorative ceramics, and building and sanitary ceramics, that can be used in industry and other sectors. It includes Industrial Ceramic products made using traditional techniques and fine ceramic materials made using advanced technologies and new processes.
In modern engineering, industrial ceramics are often referred to as Advanced Ceramic, Technical ceramics, or Engineering Ceramics. These materials use refined, high-purity, ultrafine, artificially synthesized inorganic compounds as raw materials, and are fired using precisely controlled preparation processes, resulting in specific properties.
