Abstract
A method of shortening a working and setting time of a CPC paste without using additives or sacrificing its strength, which includes heating CPC powder so that the CPC powder is maintained at a temperature of 50-400° C. for a period of time which is greater than one minute.
Claims20
A method of shortening a working and setting time of a calcium phosphate cement (CPC) paste formed by mixing a CPC powder with an aqueous solution, said method comprising heating said CPC powder, prior to said mixing, so that said CPC powder is maintained at a temperature of 50-400° C. for a period of time which is greater than one minute, and that a CPC paste formed by mixing the resulting heated CPC powder with said aqueous solution has a shortened working and setting time in comparison with that formed by mixing said CPC powder not subjected to said heating with said aqueous solution.
