Be made of high-purity ceramic powder, the ceramic tube is formed by dry pressing or cold isostatic pressing, and sintered under high temperature, then precision machined. With many advantages like abrasion resistance, corrosion resistance, high hardness, high toughness and low friction coefficient, it is widely used in medical equipment, precision machinery, laser, metrology and inspection equipment. It can work in the conditions of acid and alkali for a long time, and the maximum temperature can up to 800℃.
