Abstract

The invention discloses boron sol and a preparation method thereof. Industrial boron powder is adopted as a raw material, and a dispersion medium is one or a mixed solution of more of deionized water,ethanol, isopropanol and the like. The preparation process comprises the following steps: firstly, adding industrial boron powder into the dispersion medium according to a certain proportion, then fully stirring and ball-milling, stripping out nano boron particles by an ultrasonic method, and finally, preparing a nano boron dispersion liquid by a centrifugal method, so that the nano boron particles can be uniformly and stably dispersed into the solution to prepare a boron sol solution. The boron sol solution can be kept in a uniform and stable state for a long time, and no precipitation, layering or failure phenomenon is generated.

Description

technical field [0001] The invention belongs to the technical field of nano boron sol, and in particular relates to a stable nano boron sol and a preparation method. Background technique [0002] As a metalloid element, boron has been widely used in some high-tech fields due to its stable molecular structure and the advantages of high hardness, refractory resistance, high electrical conductivity and other properties of borides formed under high temperature conditions. Boron powder can interact with oxygen, nitrogen, sulfur, halogen and carbon to form various compounds at high temperature, and can also be directly combined with many metals to form metal borides, and can also react with organic compounds to form organic boron, which is used in the semiconductor industry , powder metallurgy additives and thermal spraying and other surface coating materials. Nano-scale boron powder, as a good filler for composite materials, improves its high-temperature oxidation process and pr...
