The chemistry of the cement-forming reaction between phosphoric acid solutions and fluorine-containing aluminosilicate glasses has been studied using a variety of physicochemical methods. These materials are the dental silicate cements and the microstructures of a number of these cements have been examined by optical, electron and scanning electron microscopy. The element distribution between partially reacted glass particles and the gel matrix which binds them has been determined by electron probe microanalysis.

The chemical stability and variations in the mechanical strength between different cements is discussed in terms of a new hypothesis on the constitution of the gel matrix. Consideration is given to the possible strengthening role of microcrystallinity which has been shown by X-ray and electron diffraction to develop in the matrix. Attempts to strengthen the cement by incorporation of reinforcing agents is described.
