The raw material conveying device for the aluminum nitride carbothermic production, disclosed by the invention, is provided with the funnel cover and the sealing device, and the funnel cover and the sealing device are used for ensuring the leakproofness of the reaction device, preventing heat in the reaction device from losing, increasing the utilization rate of the heat and saving energy source.
Description
technical field [0001] The invention relates to the technical field of production equipment for aluminum nitride carbothermal reduction, in particular to a raw material delivery device for production of aluminum nitride carbothermal reduction. Background technique [0002] The aluminum nitride carbon thermal reduction method is a new production method. The nitride powder produced by the aluminum nitride carbon thermal reduction method has fine particles and no hard agglomeration. At the same time, the reaction temperature is low and has very good performance. The thermal conductivity is high, various electrical properties are excellent, and the mechanical properties are good, but the production of aluminum nitride needs to mix aluminum hydroxide with fluoride and boride additives, put these raw materials into the reaction setup for high-temperature calcination, if These raw materials are doped with impurities or mixed unevenly, and the quality of the obtained product is not ...
