Abstract
A not quite traditional approach to the problem of melting and subsequent vitrification of silica melt and to the problem of quartz glass crystallization in heating is discussed. It is demonstrated that the system enthalpy in the vitrification of a SiO2 melt remains virtually constant up to the solidification of glass. An estimate of the activation energy of quartz glass crystallization is given.
