On the structure of some precipitated calcium alumino …

The chemistry of the calcium alumino-sulphate hydrates has been reassessed using the methods developed in a previous paper [10]. Ettringite does not have a constant solubility product. The rise in the ionic activity product of solutions in equilibrium with “ettringite” as a function of pH and sulphate activity is attributed to disordering of the crystal structure. This is due to removal of

The chemical composition of mineral trioxide aggregate

INTRODUCTION Mineral trioxide aggregate (MTA) was developed at Loma Linda University, in the 1990s, as a root-end filling material. It is used primarily to seal lateral root perforations[1,2] and as a root-end filling material.[3–6] The use of MTA as a root-end filling material was identified because the material is hydraulic and sets in the presence of water.
