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.

Fabrications of zinc-releasing biocement combining zinc calcium phosphate to calcium phosphate cement

Journal of the Mechanical Behavior of Biomedical Materials, 2014
Recently, zinc-releasing bioceramics have been the focus of much attention owing to their bone-forming ability. Thus, some types of zinc-containing calcium phosphate (e.g., zinc-doped tricalcium phosphate and zinc-substituted hydroxyapatite) are examined and their osteoblastic cell responses determined.

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 ...

Thermally Highly Stable Amorphous Zinc Phosphate Intermediates during the Formation of Zinc Phosphate Hydrate

Journal of the American Chemical Society, 2015
The mechanisms by which amorphous intermediates transform into crystalline materials are still poorly understood. Here we attempt to illuminate the formation of an amorphous precursor by investigating the crystallization process of zinc phosphate hydrate.
