Abstract

The invention provides preparation of a high-purity zinc nitride powder material, and relates to the field of zinc nitride. The preparation method of the high-purity zinc nitride powder material comprises the following steps: preparing 5N high-purity zinc, obtaining high-purity zinc particles, drying the high-purity zinc particles, preparing Zn3N2 and sieving the Zn3N2. According to the present invention, the high-purity zinc nitride is obtained by obtaining the high-purity zinc and the high-purity zinc particles, introducing the high-purity ammonia gas and well controlling the flow of the high-purity ammonia gas through finding the suitable technical conditions, and the traditional method is to obtain the zinc nitride through the precipitation of a large amount of chemical materials, but the process is complex, and the purity is difficult to ensure.

Description

technical field [0001] The invention relates to the technical field of zinc nitride, in particular to the preparation of high-purity zinc nitride powder material. Background technique [0002] Zinc nitride (Zn 3 N 2 ) has an anti-sidesiderite structure, has singular electrical and optical properties, and whether zinc oxide is an indirect bandgap or direct bandgap semiconductor, and what the bandgap is has always been a controversial issue in the industry and academia. Zinc nitride has been widely used in light-emitting diodes, solar cells, sensors and other fields. For example, in the prior art, methods such as magnetron sputtering, chemical vapor deposition, electrostatic electrolysis, and molecular beam epitaxy can be used to produce zinc nitride. [0003] The existing zinc nitride preparation process is complicated, which is not conducive to the production of zinc nitride, especially the preparation of high-purity zinc nitride powder. In the production of zinc nitride...
