Matusevich] Conclusions: We presented the results of studies conducted to obtain unfired quartz ceramics according to the method involving impregnation of the products in a liquid glass solution (modulus A) having a density of 1.07-1.15 g/cm3 and subsequent treatment in an aqueous solution of ammonium nitrate (ammonium saltpeter). With respect to the mechanical properties, the unfired ceramics are considerably superior to the conventional fired ceramics at heat-treatment temperatures ranging from 200 up to 1200°C. By impregnating the products with liquid glass and treating them subsequently in the aqueous solutions of the nitrate salts of ammonium, chromium, magnesium, zirconium, beryllium, and cerium, we obtained quartz ceramics containing (alloyed with) the oxides of these metals and possessing a high resistance to molten metals and slags.
