Conclusions Vitrified quartzite (density 2.29 g/cm3) containing 86–96% of a vitreous phase and 14–4% of a crystalline phase (quartz, cristobalite) has been obtained by roasting in a sintering plant by the suction method. The authors have developed compositions of refractory concretes with a vitrified quartzite filler based on sodium hexametaphosphate, aluminophosphate binder, and water glass. The concretes have a nonshrinking structure, high onset temperatures of deformation under a load of 2 kgf/cm2, and a high heat resistance. |
