    • The present invention relates to a thermal plasma apparatus for manufacturing aluminum nitride powder, including a conic cyclone, having a pipeline formed vertically in the middle of the cyclone to provide a channel for transferring aluminum nitride powder to a capture part, and having the structure of a distance between the outer wall of the pipeline and the inner wall of the cyclone decreasing in a direction from the upper part of the cyclone to the lower part of the cyclone. Therefore, the present invention can synthesize and capture high-purity aluminum nitride (AlN) powder efficiently by pyrolyzing aluminum source materials and nitrogen source gas using plasma, making aluminum (Al) components react with nitrogen (N) components, and inducing the formation of nuclei and the growth of particles.
    • 本发明涉及一种用于制造氮化铝粉末的热等离子体装置,其包括圆锥旋风分离器,其具有在旋风分离器中部垂直形成的管线,以提供用于将氮化铝粉末转移到捕获部分的通道,并且具有 管道的外壁和旋风分离器的内壁之间的距离在从旋风分离器的上部到旋风分离器的下部的方向上减小。 因此,本发明可以通过使用等离子体热解铝源材料和氮源气体来有效地合成和捕获高纯度氮化铝(AlN)粉末,使得铝(Al)组分与氮(N)组分反应,并诱导形成 核和颗粒的生长。
