Microstructure analysis of novel resorbable calcium phosphate/sulphate bone cements

Research output: Contribution to journalArticle

Abstract

This paper presents a new method to obtain porosity in apatitic cements, by mixing a-tricalcium phosphate (alpha-TCP) with calcium sulphate hemihydrate. The material was characterized by X-ray diffraction and observations in Electron Microscopy. The results show that crystals of calcium sulphate stayed embedded in the hydroxyapatite formed from a-TCP. By dissolution of these crystals porosity could be obtained where new bone tissue could grow in and resorb the cement.
