  • Process for affecting the setting and working time of bioresorbable calcium phosphate cements
    Publication number: 20050279256
    Abstract: A fast-setting, bioresorbable calcium phosphate cement is prepared by a process which can be carried out with a heat treatment up to 1000° C. on a mixture of a wetting solution and a calcium phosphate powder having a Ca to P molar ratio of 0.5-2.5. The wetting solution suitable for use in the process of the present invention includes water, an organic solvent, an acidic and basic solution. A setting solution for mixing with the heated powder to form the fast-setting, bioresorbable calcium phosphate cement may be water, an acidic or basic solution according to the process of the present invention.
