Abstract

The invention discloses a charging container for combustion, a charging method of the charging container for the combustion and a synthesis method of high alpha-phase silicon nitride. The charging container for the combustion comprises a charging boat for charging and is characterized in that the charging boat is a hollow structure with an opening at the top, the charging container for the combustion further comprises heat-insulating materials, and the hollow structure of the charging boat is internally filled with air-permeable heat-insulating materials; or the surface of the charging boat isprovided with the air-permeable heat-insulating materials. According to the charging container for the combustion and the charging method of the charging container for the combustion, the ignition success rate is ensured to reach 99% or above, the combustion efficiency is high, the smooth progress of combustion is guaranteed, it is ensured that no burning phenomenon occurs in the spreading process during combustion, the amount of recycled powder is small, and the picking workload of unburnt materials after combustion is reduced, meanwhile, the combustion time and the post-end discharge powdermaterial treatment period are greatly shortened, dust pollution in the prior art operation process is avoided, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of combustion charging, and in particular relates to a combustion charging container, a charging method thereof, and a synthesis method of high-α-phase silicon nitride. Background technique [0002] As an emerging powder material, silicon nitride is widely used in photovoltaics, machinery, chemicals, semiconductors, ceramics and other industrial fields because of its good mechanical strength, chemical properties, thermal shock resistance and electrical insulation. In the known silicon nitride production technology, the nitridation time of the direct nitridation method is long and the power consumption is high. To produce high-quality products requires not only fine control of the process, but also strict requirements on equipment. But its production efficiency is low, and the silicon nitride powder produced at the same time is conventional low-quality ceramic powder; the ammonolysis method uses silicon tetra...
