Crystallization of zinc phosphate cement

The Journal of Prosthetic Dentistry, 1965
Abstract A microscopic study indicated that ZnHPO 4 ·3H 2 O was formed during the crystallization of zinc phosphate cement powder and liquid. Long crystals of ZnHPO 4 ·3H 2 O radiated from a nucleus of crystallization. Apparently, the surface tension force plays a role in partially inhibiting the growth of these crystals.

Structure of Zinc Phosphate Dental Cement

Journal of Dental Research, 1971
The zinc phosphate cement structure consists of excess zinc oxide particles in a non-crystalline, amorphous phosphate matrix. Crystals of hopeite (Zn3(PO4) 2·4H2O) can grow from the cement surface if excess water is present. Extensive pores and surface layers of crystals, which are dependent on moisture conditions, affect the strength and adhesive ...

Surface Structure of Zinc Phosphate Dental Cements

Journal of Dental Research, 1972
When zinc phosphate cement is formed enclosed between a glass plate and a tooth surface, it retains the excess moisture available at the time of setting. This causes the cement surfaces to become covered with weakly held crystals of hopeite (3 ZnO·P2 O5 · 4 H2O).
