Abstract
Conditions of synthesis from elements of pure superfine powder of boron silicide B4Si are investigated. It is shown that the silicide phase forms on boron particles and B4Si particles inherit the shape and size of initial boron particles, which makes it possible to control the particle size of the powder obtained. The oxidation of pure boron silicide and materials based on it in air and their optical properties are studied. It is shown that chromium diboride added to boron silicide increases the oxidation resistance of B4Si and hardly decreases its absorbance. The B4Si-CrB2 material can be successfully introduced into the compositions of heat-protective coatings operating in air at 1300 °C.
