Novel device for generating silicone imine continuously

Abstract

The invention provides a novel device for generating silicone imine continuously. The novel device comprises a reactor, an input device and a flash evaporator, wherein the input device is used for inputting liquid ammonia, nitrogen and SiC14 into the reactor, and the flash evaporator is used for carrying out solid-liquid separation on a product of the reactor. The novel device is characterized in that the reactor comprises a spraying washing area, a reaction area and a sediment area which are sequentially arranged from top to bottom, and are integrated. By integrating the sediment area, a SiC14 distributor, a pool separator, the reaction area, the spraying washing area and the two-stage flash evaporator, the novel device for generating the silicone imine has the advantages of being flexible to operate, high in converting rate and product purity, low in raw material loss, and capable of generating the silicone imine continuously.

Description

technical field [0001] The invention relates to a continuous production device for silicon imine, a precursor of silicon nitride powder, or its polymer / mixture produced by thermal decomposition of silicon amine, in particular to a novel device for continuous production of silicon imine. Background technique [0002] The silicon nitride powder produced by the thermal decomposition of silicon amine is the main source of high-end ceramic materials / ceramic matrix composites with high purity and ultrafine, high alpha phase content, and high sintering activity (such as preparation of ceramic engines / parts, large-size ceramic bearings / ball). Research and development of silicon nitride powder precursor silicon imide or its polymer / mixture new device generated by the thermal decomposition of silicon amine is a positive response to the "New Material Industry "Twelfth Five-Year" Development Plan" and "New Material Industry The "Twelfth Five-Year" Key Product Catalog of the Industry" ...
