ZINCOPHOSPHATE CEMENTS – HARDENING MECHANISMS. Authors: ION TEOREANU, CRISTINA DUMITRESCU. |
||||||
Abstract: Phosphate binders mostly, and zincophosphate dental cements especially, base their hardening on acid-base reactions, in which the liquid component is an aqueous phosphate solution and the solid component is usually an amphoteric, and only rarely basic one. In the present paper, investigations of the hardening mechanisms of zincophosphate cements were performed using X-ray diffraction analysis, IR spectroscopy, and scanning electron microscopy. The phase evolution of the hardening system and the microstructure of the hardenend binder were highlightened related to the specific mechanisms of the hardening process—specific to phosphate binders. | |||||||
