The process of dissolution of cristobalite during the calcination of acid-resistant articles based on Buskul’skoe clay using granodiorite and felsites is simulated. The mechanism governing the dissolution of cristobalite in their melts is determined. The process of dissolution of cristobalite in felsite and granodiorite melts can be divided into two stages. First, for short holding times, the rate of dissolution is determined by the rate of silicate formation during the interaction of the melt, formed by heating felsite or granodiorite, with cristobalite. Second, for long holding times, the rate of dissolution is determined by the rate of diffusion, the rate of dissolution decreasing substantially.
