As we all know, alumina is the most flexible and inexpensive material among oxides with melting points over 2000°C. And alumina ceramics are the most widely used, the most versatile and the most productive ceramic materials among oxide ceramics. Alumina ceramics have the advantages of high hardness, good mechanical properties, good heat resistance, good electrical insulation properties, chemical stability and high temperature corrosion resistance, etc. With the continuous development of advanced ceramic industry, alumina ceramics towards, high purity, microcrystallization, advanced direction of production equipment!
And the choice of quality raw materials will be the first step to improve the quality!
