Microstructure and properties of alpha-tricalcium phosphate-based bone cement

摘要

This paper examines the physicochemical properties and microstructure of brushite calcium phosphate cements possessing strength acceptable for application in surgery (15-20 MPa) and ensuring an optimal acidity (pH 6.5-7.5) of solutions in contact with them. Holding in a physiological saline produces significant changes in the microstructure of the cement relative to that before immersion in the solution: it causes a transformation of the most soluble components into platelike hydroxyapatite crystals.
