利用显微镜、SEM、XRD和化学分析等手段研究磁场作用下形成磷酸盐的形态和结构以及相应溶液的变化。结果表明磁场作用下的磷酸钙盐结构上有多相生成 ,得到较小的颗粒。测得有关溶液经磁场作用后电导率、表面张力有所下降 ,4 8小时后溶液中磷的含量经磁场作用的比未经磁场作用的高 2 .2倍。认为磁场对弱酸在水溶液中的电离平衡影响较大 ,并且能改变晶体表面的电荷分布和晶体与溶液间的扩散层。在这种化学和物理的共同作用下 ,抑制了磷酸盐的晶格长大。 Using the microscope, SEM, XRD and chemical analysis methods to study the formation of phosphate under the action of magnetic field morphology and structure and the corresponding solution changes. The results show that the magnetic field under the structure of calcium phosphate multiphase structure, resulting in smaller particles. Measured about the solution after the magnetic field conductivity, surface tension decreased, 4 8 hours after the solution of phosphorus in the magnetic field than the role of the role of the high 2.2 times. It is considered that the magnetic field has a great effect on the ionization balance of the weak acid in aqueous solution and can change the charge distribution on the crystal surface and the diffusion layer between the crystal and the solution. Under this chemical and physical interaction, the lattice growth of the phosphate is inhibited.
