Atomization spray disc, spherical silicon boride ceramic powder, and preparation method and application of spherical silicon boride ceramic powder
The invention belongs to the technical field of silicon boride ceramic powder production, and particularly relates to an atomization spray disc, a spherical silicon boride ceramic powder, and a preparation method and application of the spherical silicon boride ceramic powder. The atomization spray disc comprises: a liquid guide pipe; a crucible positioning circular truncated cone, wherein the smaller bottom surface of the crucible positioning circular truncated cone is connected with the inlet of the liquid guide pipe, so that the molten liquid enters the liquid guide pipe along the crucible; and atomized gas inlet pipes located on the two sides of the liquid guide pipe, wherein spraying holes are formed in the ends, close to the liquid guide pipe, of the atomized gas inlet pipes. The atomized gas is suitable for being sprayed out from the spraying holes in the two sides so as to crush the molten liquid to form powder particles. According to the atomization spray disc, the problems of obtaining of silicon boride spherical powder and uniformity of composite material components are solved, so that silicon boride ceramic powder which is high in sphericity degree, good in fluidity and smooth and stable in conveying state is obtained, and the silicon boride ceramic powder can be used as a research and development material of a spraying coating and a boron-doped novel battery silicon negative electrode material.
