✦ Synopsis
ABST~ACT
Solid solutions of ettringites containing SO42-,B(OH)4and CRO42-were investigated. The compositions of the solid solutions under different synthesis conditions are represented by paste reaction (I) and "saccharate method" (2):
The crystallographic properties of the different solid solution series were determined. An interpretation of the ternary solid solutions is given.
