| 摘要 |
Refrigerated hydraulic cement compositions comprise a mixture of (a) β-tricalcium phosphate powder, (b) monocalcium phosphate comprising monocalcium phosphate anhydrous (MCPA), monocalcium phosphate monohydrate (MCPM), or a combination thereof, wherein a 0.1 g/ml saturated aqueous solution of the monocalcium phosphate has a pH less than 3.0, (c) non-aqueous water-miscible liquid, and (d) an aqueous hydrating liquid. The aqueous hydrating liquid is included in an amount of about 1-50 volume percent, based on the combined volume of the non-aqueous water-miscible liquid and the aqueous hydration liquid, and the refrigerated hydraulic cement composition is storage stable for greater than one day, without setting. Methods of forming hardened cements in vivo and/or for forming implants for use in vivo employ the hydraulic cement compositions. |
