Market Development Present Situation of Alumina Ceramics in China

Alumina ceramic is a kind of ceramic material using alumina (Al2O3) as the main body, used in thick film integrated circuit. Alumina ceramic has good conductivity, mechanical strength and high temperature resistance, and needs to use ultrasonic washing.

Alumina ceramic is mainly divided into regular type and high purity type. High purity alumina ceramic is a kind of ceramic material whose Al2O3 content is more than 99.9%, while regular alumina ceramic can be divided into 99, 95, 90, 85 and other varieties according to different Al2O3 content. Sometimes, its Al2O3 content is 80% or 75% and they are still classified as ordinary alumina ceramic series.

Alumina ceramic has high mechanical strength, high insulation resistance, high hardness, wear resistance, corrosion resistance, high temperature resistance and a series of other excellent performances, which can make thick film integrated circuit, resistance furnace tube, insulating material, wear-resistant materials and other components and materials.

Chinese alumina ceramic is widely used in ceramics, textiles, petroleum, chemical industry, construction, electronics and other industries, which is currently the most widely used and biggest new ceramic material in oxide ceramics.

According to related data, domestic alumina ceramic production enterprises are mainly concentrated in Henan, Shandong, Jiangsu and Shanghai. China's alumina ceramic market volume has fundamental equilibrium.

In the current process and technical conditions of existing products, the alumina ceramic industry is developing rapidly. With countries’ support for emerging industry, our high-tech industry country mainly depending on aerospace will get rapid growth in the future, and the sustainable development of machinery manufacturing, power electronics, medical and other field will bring great benefits for alumina ceramic industry.
