Background
The ceramic is made up by using natural clay and various natural minerals as main raw materials and making them pass through such processes of pulverizing, mixing, forming and calcining. Articles made of pottery clay and fired at high temperature in special kilns have been called ceramics, which are a general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products which take inorganic nonmetallic minerals such as clay and the like as raw materials. It includes various products made up by using clay or clay-containing mixture through the processes of mixing, forming and calcining. High purity alumina ceramics refer to ceramic materials having an alumina content in excess of 99.9%. Since the sintering temperature is up to 1650-. The product can be used as sodium lamp tube due to its light transmission and alkali-proof metal corrosion; can be used as an integrated circuit substrate and a high-frequency insulating material in the electronic industry.
Ceramics have been widely used in structural ceramics, functional ceramics and ornaments because of their advantages of high toughness, high bending resistance and high wear resistance, and thus have higher requirements for the surface processing of ceramics. Grinding of ceramic materials is one of the most used methods in existing machining processes.
