Preparation of Monetite (CaHPO4) with Hexagonally Packed Mesoporous Structure by a Sol–Gel Method Using Cationic Surfactant Aggregates as a Template

Abstract

Abstract We first-successfully fabricated mesoporous calcium phosphates by a regular sol–gel method using cationic surfactant aggregates as a template. Low-angle XRD and TEM observation indicated that a product included hexagonally packed mesoporous structure. Wide-angle XRD and FT-IR observation identified the product as monetite (CaHPO4), which is one of calcium phosphates.
