실험 절차
Example 1 was repeated with the addition of 10.00 g dicalcium phosphate dihydrate, DCPD, CaHPO4.2H2O (Aldrich Chemical Co., Inc. #30,765-3, CAS #7789-77-7) to the homogeneous solution following endothermic dissolution of the calcium nitrate salt. The DCPD was present both as suspended solids and as precipitated material (no agitation used). Warming of the sample to >25° C. initiated an exothermic reaction as described in Example 1, resulting in the formation of a white, pasty solid. Heat treatment and X-ray diffraction of this solid were conducted as described in Example 1. Following heat treatment in air at 500° C. for 1 hour, XRD indicated the solid to be composed of whitlockite as the primary phase along with calcium pyrophosphate (Ca2P2O7) as the secondary phase.
