Abstract
The matrix effect of silicon on the intensity of analytical lines of admixtures has been studied in the systems silicone oxide-graphite powder and silicon oxide-carrier-graphite powder. The composition of the spectroscopic buffer and the conditions of the direct spectrochemical analysis of oxide-silicate materials (brick, concrete, refractory materials, slags, glass, ceramics, etc) have been optimized. An atomic emission procedure has been proposed and its preliminary performance characteristics have been estimated.
