High-temperature and high-pressure silicon nitride powder preparation device adopting self-propagating method
The invention discloses a high-temperature and high-pressure silicon nitride powder preparation device adopting a self-propagating method. The silicon nitride powder preparation device comprises a furnace body, a skip car, a feeding system, a self-propagating reaction ignition system, a vacuum system, a gas path system, a cooling system and an automatic control system, wherein a reaction space is formed in the furnace body; controllable large-scale silicon nitride self-propagating preparation can be provided, and high-purity silicon nitride can be obtained. According to the high-temperature and high-pressure silicon nitride powder preparation device adopting the self-propagating method, the characteristics of the self-propagating method are utilized, ignition heating is performed, an exothermic reaction is utilized for reaction, and energy is saved. By arranging a transmission system, a furnace door adopts a (left or right) door opening mode and an automatic opening and closing structure, and the automation degree is high.
