Alumina is the most widely used materials in oxide materials, especially whose purity is higher than 99.5%. This ceramic material has superb properties such as high hardness, high wear resistant, high mechanical strength, perfect high temperature resistance, antioxidation stability, high chemical-resistance, high electrical insulation etc. High purity alumina is one of the most important ceramic materials. Alumina part is substitute for plastics, metals or other conventional materials. Alumina ceramic part is widely used in a wide range of industrial fields such as Machinery, Textile, Petroleum, Chemical, Metallurgy, Refractory and Electronic industries.
