    Notes: Abstract The cement-forming characteristics of selected chain, sheet and framework silicates when mixed with aqueous solutions of acrylic acid polymers have been investigated using infrared spectroscopy, X-ray diffraction, chemical analysis and the measurement of physical properties. The initial stages of the cement-forming reaction were investigated by measuring the release of elements from minerals into acid solution and estimating the extent of mineral decomposition. The degree of neutralization and the structure of the polysalt matrix were determined by infrared spectroscopy.

    Notes: Phosphorus-31 nuclear magnetic resonance spectroscopy of phosphoric acid solutions containing zinc and aluminium indicates that zinc forms simple salts in solution, whereas aluminium forms a number of complexes, some of which are polymeric. The formation of the aluminophosphoric acid complexes controls the gelation and strengthening of the dental silicate cement and prevents the formation of crystalline zinc phosphate in the zinc phosphate cement.

    Notes: The particle size and adsorbed water on zinc oxide from various sources have been investigated and related to the reactivity with eugenol. The reactivity of zinc oxide with eugenol alone increases with the amount of water reversibly adsorbed. When 1% acetic acid is added to eugenol, the reactivity increases as the particle size of the oxide decreases. Generally, zinc oxide powders are deactivated by heat treatment because of coalescence of particles and loss of the ability to readsorb water.
