摘要

Whitlockite (WH)是一种重要的磷酸钙(CaP)材料，具有令人惊讶的生物学特性。羟基磷灰石、β-磷酸三钙等合成难度较小的cap材料已做了大量的研究。在这项研究中，我们揭示了一种简单的结合策略，利用白云石，通过沉淀合成WH。目的是通过在不同温度下，在几乎没有介质的环境下，对所得粉末进行搅拌、时效和热处理来完成。采用热重(TGA)、x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、扫描电镜(SEM)、抗菌试验和蛋白质吸附等方法对所得粉末进行分析。XRD检测证实所得材料为whitlockite。体外实验证明，所得WH具有良好的生物相容性。该技术为WH的大规模生产提供了简单的方法。

Effect of heat treatment temperature on whitlockite prepared using Dolomite

Whitlockite (WH) is a significant calcium phosphate (CaP) material due to its surprising biological properties. Much work has been done on different CaPs like hydroxyapatite and β-tricalcium phosphate which are not hard to synthesize. In this study, we are revealing an easy union strategy for WH synthesis, utilizing dolomite, by precipitation. The objective was completed by stirring, aging, and heat treating the obtained powder at different temperatures, with practically no medium, under the ambient environment. The powder gotten was analyzed by thermogravimetric (TGA), x-ray diffraction (XRD), Fourier changes infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), anti-bacterial test, and protein adsorption. XRD examination affirmed that the obtained material is whitlockite. The in-vitro tests proved that the obtained WH is biocompatible. The technique gives simple method for large-scale manufacturing of WH.
