Shanghai Silicate Institute has made new progress in the preparation of large-size / complex shape high-purity alumina parts by spontaneous solidification molding

2022-03-14

Recently, the scientific research team led by researcher Wang Shiwei of Shanghai Institute of silicate, Chinese Academy of Sciences, cooperated with Jiangxi zhongkete ceramic new materials Co., Ltd. to break through the key bottlenecks such as deformation and cracking of large-size ceramic blank during drying and sintering based on the spontaneous solidification molding system with independent intellectual property rights, The super large-size high-purity alumina ceramic disc with a diameter of 1010mm (Fig. 1) and the double-layer concentric high-purity alumina cylinder with an outer diameter of 200mm (Fig. 2) were successfully prepared. The main performance indexes of the material are better than those of similar foreign products.
