Solubility of a Silicate Cement

Journal of Dental Research, 1970
Samples of a silicate cement were soaked in different environments for varying lengths of time. The resulting solutions were analyzed for Na, Zn, Ca, Al, and Si by atomic absorption spectrophotometry. All of the elements showed a decreasing rate of solution with increasing time.

Solubility of silicic acid

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1956
1. The solubilities of silicic acid gels in water at 25.9° and 97° were studied. 2. It was shown that the silicic acid that passed into solution was present entirely in, the form of simple molecules and ions capable of reacting with molybdic acid.

Structure of Soluble Silicates

MRS Proceedings, 1984
ABSTRACTSmall angle x-ray scattering (SAXS) is the technique of choice for the determination of structure on the 10–1000Å scale. We have used this technique to study the growth and topology of the macromolecules which precede gelation in several chemical systems used in sol-gel glass technology.

Solubility limits of silicate melts

The Journal of Chemical Physics, 1997
A statistical mechanical model of silica melt is presented in which metal oxides are incorporated into the bonding network. In this approach a Flory-type lattice model for binary silicate melts is coupled with a set of chemical reactions that determine the extent of metal oxide incorporation into the silica network and regulate the distribution of ...
