Alumina ceramic is the most widely used fine ceramics material. Alumina ceramic material has superb material characteristics such as high electrical insulation, high mechanical strength, high wear and chemical resistance, and excellent thermal stability, which makes it widely used in areas of high temperatures resistant required.
The industrial ceramics manufacturing process typically involves a number of stages. The process starts with preparing the raw materials for fabrication. Via pressing or molding methods, making the raw materials into green ceramic parts. Then firing or sintering them into shape using a chemical process. Finally, the ceramic is finished via different forms of polishing and glazing.
