Abstract

The electron spin resonance (ESR) spectra of vanadyl ions (VO2+) adsorbed on amorphous calcium phosphate (ACP), formed under varying conditions, were measured at room temperature. They varied with the variation of the conditions and were different from those of other calcium phosphates. The present result suggests that ACP is a distinct and a separate compound from other calcium phosphates and that ACP is a noncrystalline form of Ca3 (PO4)2 X 3 H2O or a solid solution of the composition of Ca3(PO4)1.87(HPO4)0.2, which was proposed previously.

摘要

在室温下测量了在不同条件下形成的吸附在无定形磷酸钙（ACP）上的钒酰离子（VO2+）的电子自旋共振（ESR）光谱。它们随条件的变化而变化，并且与其他磷酸钙的光谱不同。目前的结果表明，ACP是一种与其他磷酸钙不同的独立化合物，并且ACP是Ca3(PO4)2·3H2O的非晶态形式或先前提出的Ca3(PO4)1.87(HPO4)0.2组成的固溶体。
