SOME ASPECTS OF THE INTERACTION OF GLASS BINDER COMPONENTS DURING HEAT TREATMENT ACCORDING TO THE GLASS PHASE CONTENT
Аннотация
This article presents generalized data on the synthesis of glass-crystalline materials based on flotation wastes. Optimal structures of glass-crystalline materials and technological parameters based on the composition Kaolin-quartz sand-flotowaste of the fluorite concentrator are developed. There have been determined the physico-chemical properties of glass-crystalline materials. This work aims to study the production of glass-crystalline material at low synthesis temperatures (not exceeding 900oC). The binder was studied for obtaining glass crystallite of the following chemical composition (%* – Hereinafter mass content):69,00 SiO2, 7,80 Al2O3, 1,56 Fe2O3, 3,65 CaO, 0,10 MgO, 0,15 BaO,12,70 Na2O, 1,70 K2O, 4,50 CaF2, 4,00 cryolite. At the same time, quartz sand was completely excluded from the factory composition and the amount of the glass crystallization initiator, cryolite, was significantly reduced. The production binder was also studied for comparison.
