Demonstration of metastable paragenesis in the process of solid phase interaction in the system of СаО – Al[2]O[3] – SiO[2]

Abstract

A short characteristic of new type of foreign dental cements Mineral Trioxide Aggregate (MTA) for root canal dressing is presented. The results of experimental researchesdealing with the development of the composition and method of producing of the national dental cement of the similar purpose. The effect of modifying additions (CaF2, P2O5, Bi2O3, MgO) on the sintering process of clinkers was studied and the demonstration of metastable paragenesis in the of solid phase interaction in the system CaO – Al2O3 – SiO2 was found. The obtained results provide more reliable designing of the mineralogical composition of cement clinker.
