Description

technical field [0001] The invention relates to the field of powder production atomization technology, in particular to an atomization device and system for high-efficiency production of aluminum nitride powder. Background technique [0002] Aluminum nitride is a crystalline material with good performance, which has high thermal conductivity, good mechanical properties, high flexural strength, high purity, and good optical transmission characteristics, so it is a promising high-power integrated circuit substrate sheets and packaging materials. [0003] However, the existing aluminum nitride powder production equipment has poor practicability and low safety, and the powders produced are of different sizes, requiring secondary processing, low production efficiency, and incomplete reactions often occur. Therefore, it is necessary to design an atomization device and system for high-efficiency production of aluminum nitride powder with improved production efficiency and sufficie...
