| description | Fine biocompatible powders with different phase compositions were obtained from a 0.5 M solution of ammonium sulfate (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub> and calcium lactate Ca(C<sub>3</sub>H<sub>5</sub>O<sub>3</sub>)<sub>2</sub>. The powder after synthesis and drying at 40 °C included calcium sulfate dehydrate CaSO<sub>4</sub>·2H<sub>2</sub>O and calcite CaCO<sub>3</sub>. The powder after heat treatment at 350 °C included β-hemihydrate calcium sulfate β-CaSO<sub>4</sub>·0.5H<sub>2</sub>O, γ-anhydrite calcium sulfate γ-CaSO<sub>4</sub> and calcite CaCO<sub>3</sub>. The phase composition of powder heat-treated at 600 °C was presented as β-anhydrate calcium sulfate β-CaSO<sub>4</sub> and calcite CaCO<sub>3</sub>. Increasing the temperature up to 800 °C leads to the sintering of a calcium sulfate powder consisting of β-anhydrite calcium sulfate β-CaSO<sub>4</sub> main phase and a tiny amount of calcium oxide CaO. The obtained fine biocompatible powders of calcium sulfate both after synthesis and after heat treatment at temperature not above 600 °C can be recommended as a filler for producing unique composites with inorganic (glass, ceramic, cement) or polymer matrices. |
