Bryzgalov1, P.V. Volkov2</p><p>The influence of heat-treating on the microhardness of the silica glass K -1 is investigated. It is found out that the heat-treatment at 1100 C increase in microhardness and the uniformity improves. This fact is explained by the change of the phase composition of the surface, namely by the appearance of re-flexes, related to the phase of cristobalite. </p><p>Keywords: silica glass K -1, microhardness, heat-treatment, X-ray analysis, cristobalite. </p><p>References 1.
