Effects of Heat Treatment on Phase Formation in Cytocompatible Sulphate-Containing Tricalcium Phosphate Materials

Powders based on β-tricalcium phosphate (β-TCP) containing sulphate groups at up to 12.0 mol.% were synthesised by chemical precipitation from aqueous solutions. The obtained materials characterised X-ray phase analysis, Fourier transform infrared spectroscopy, measurement of specific surface area, scanning electron microscopy, energy dispersive synchronous thermal mass spectra investigations and biological assays. It was established that during the synthesis, lose in course heat treatment 900 or 1200 °C. These stabilise low-temperature β-TCP, but when introduced a high concentration, contribute formation hydroxyapatite treatment. Specific area powders proved be range 81.7–96.5 m2/g. Results assays showed cytocompatibility both pure β-TCP samples sulphate-containing β-TCP. Additionally, matrix properties culture MG-63 cells revealed all samples. Thus, are promising for biomedical applications.
