Method for synthesizing boron phosphide polycrystalline block by using amorphous boron source and phosphorus source through one-step method
The invention is applicable to the technical field of boron phosphide polycrystalline synthesis, and provides a method for synthesizing a boron phosphide polycrystalline block by using an amorphous boron source and a phosphorus source through a one-step method, which comprises the following steps: fully ball-milling and mixing amorphous boron powder and amorphous phosphorus powder; pressing the raw materials into a cylinder; the cylinder is placed in a high-pressure assembly, then the high-pressure assembly is placed in a cavity of a cubic press, and heating is conducted for 60 min under the conditions that the pressure ranges from 2 GPa to 5 GPa and the temperature ranges from 950 DEG C to 1350 DEG C. The invention also provides a boron phosphide polycrystalline block and an application of the boron phosphide polycrystalline block in preparation of a high-heat-dissipation device. The boron phosphide polycrystalline ceramic sintered body is synthesized at high temperature and high pressure through a one-step method by adopting a domestic cubic press, the cost is low, the time is short, the process is simple, the pressure is relatively low, and the yield is high; the synthesized sample has the characteristics of simple process, high hardness, high heat conductivity and the like, has very wide application potential, can be used for superhard inorganic compounds, refractory materials, high heat dissipation devices or ships and the like, and can prevent ship bodies and parts from being corroded by seawater and the like.
