The effect of a magnetic field on the crystallisation and morphology of CaCO₃ in solution was investigated in the 25–80 °C temperature range. The samples were analysed using X-ray diffraction, FTIR, SEM analysis and quantitative analysis based on the Rietveld method. It was demonstrated that the magnetic field, which varied from 50 to 175 mT, had an impact on the polymorphs selectivity and their proportions and on the morphology and the sizes of the CaCO₃ particles. It also reduced the overall precipitation rate of CaCO₃ minerals in the solution. SEM images showed that the magnetic field modifies the shape of the rhombs of calcite as reflected by the destruction of the particles at 25 and 50 °C with a considerable decrease in their size at 80 °C. These results demonstrate the effectiveness of a magnetic field in reducing the adhesion of calcite to surfaces and thus its possible application in limiting the formation of scale in industrial installations.

在 25–80 °C 的温度范围内研究了磁场对溶液中 CaCO ₃结晶和形态的影响。使用X射线衍射、FTIR、SEM分析和基于Rietveld方法的定量分析对样品进行分析。结果表明，从 50 到 175 mT 变化的磁场对多晶型物的选择性和它们的比例以及 CaCO ₃颗粒的形态和尺寸有影响。它还降低了 CaCO ₃的整体沉淀率溶液中的矿物质。SEM 图像显示磁场改变了方解石菱形的形状，这反映在 25 和 50°C 时颗粒被破坏，在 80°C 时它们的尺寸显着减小。这些结果证明了磁场在减少方解石对表面的粘附方面的有效性，并因此证明了它在限制工业装置中水垢形成方面的可能应用。
