Synchrotron X-ray diffraction investigations were performed to study the reactivity of a nanolime produced by an innovative method based on an ion exchange process, both in aqueous and in alcoholic suspensions. Moreover, for the first time, the nanolime reactivity was investigated both on laboratory glass slides and directly on artistic relevant stones, the biocalcarenite of Agrigento. The results showed that only aqueous suspension exhibits a complete conversion into calcite. The transformation is favoured on porous stone surface, allowing the nanolime suspension to be absorbed and dispersed, increasing the CO₂ diffusion.

同步加速器研究生物钙钙石石材表面的纳米石灰反应性

进行了同步加速器X射线衍射研究，以研究通过基于离子交换过程的创新方法生产的纳米石灰在水性悬浮液和酒精悬浮液中的反应性。此外，首次在实验室载玻片上和直接在艺术相关的石头（阿格里真托的生物钙钙石）上研究了纳米石灰的反应性。结果表明，仅水性悬浮液显示出完全转化为方解石。该转化在多孔石材表面上是有利的，允许纳米石灰悬浮液被吸收和分散，从而增加了CO _2的扩散。
