Properties and reaction processes at the hardening of some aluminate-silicate-fluoride phosphate binders

The silicate-phosphate cement represents a phosphate dental binding material, obtained by mixing a solid powdered compound with a solution of partially neutralised ortophosphoric acid. This type of cement can be used for the restoration of the frontal teeth and also for fixing the dental crowns. It has better mechanical properties and hydrolytic stability as compared to ZnO-phosphate cement and a cariostatic action due to its fluoride content. The goal of the paper is to provide information concerning the influence of the thermal treatment of the powder and of some compositional characteristics on the properties of silicate-phosphate binders.
