Composite Cement Materials Based on Calcium Sulfate and Phosphate for Medicine

Abstract

Composite materials based on α-tricalcium phosphate and reinforced with calcium sulfate dihydrate (gypsum) granules were studied. In these materials, pores can form in vivo in the medium of the human body because of selective gypsum dissolution. Such materials can be promising for cell technologies of bone tissue regeneration. Such characteristics of the composite materials as phase composition, setting time, compressive strength, and kinetics of dissolution were investigated, depending on content and size of granules. The materials with the setting time and strength suitable for surgery applications were obtained.
