High-hardness ceramics

Aluminum nitride ceramics, as a high-performance ceramic material with high thermal conductivity, electrical insulation and mechanical strength, are widely used in electronics, aerospace, chemical and other fields. In the preparation process of aluminum nitride ceramics, forming technology is one of the key links, which affects the performance and quality of ceramic materials. At present, tape casting, injection molding and compression molding are commonly used molding methods in the preparation of aluminum nitride ceramics. Press molding technology is a more traditional molding method, which is mainly applicable to the preparation of aluminum nitride ceramic products with simple shapes and low dimensional accuracy requirements. The technology is based on mixing aluminum nitride powder with the appropriate amount of organic additives and placing it into a mold, using external pressure to make the powder particles rearranged and tightly combined to form a dense billet.
