We applied microwave light with frequencies 10, 212, and 419 GHz to form octacalcium phosphate (OCP) intercalated with succinate ions (SCI). The composition of starting reagents (i.e., α-type tricalcium phosphate (TCP), calcium hydrogenphosphate dihydrate (DCPD), and SCI in pure water) did not enable us to form OCP intercalated with SCI in a thermostatic water bath. Although microwave irradiation typically acts as a heat source in water, it has brought a valuable contribution to OPC formation. This paper reports the following interesting result; microwave irradiation of power less than 0.1 W enabled us to synthesize OCP intercalated with SCI which was not possible to form with power values exceeding 0.1 W.

微波对嵌入琥珀酸根离子的八磷酸钙形成的贡献
我们使用频率为10、212和419 GHz的微波形成嵌入琥珀酸离子(SCI)的磷酸八钙(OCP)。起始试剂(即纯水中的α型磷酸三钙(TCP),磷酸氢钙二水合物(DCPD)和SCI)的组成无法使我们在恒温水浴中形成嵌入SCI的OCP。尽管微波辐射通常在水中充当热源,但它为OPC的形成做出了宝贵的贡献。本文报告了以下有趣的结果;功率小于0.1 W的微波辐射使我们能够合成嵌入SCI的OCP,而功率超过0.1 W则无法形成。
