Synthetic calcite (CaCO) particles are found in a broad range of applications. The geometry of particles produced from limestone or precipitation are versatile but limited to basic shapes. The microalga produces micro-structured calcite platelets, called coccoliths. This article presents the results of an application-orientated study, which includes characteristic values also used in the calcite industry for particle evaluation. It is demonstrated that coccoliths are significantly different from all industrial particles produced so far. Coccoliths are porous particles, mainly consisted of calcium carbonate, with further elements such as Mg, Si, Sr, and Fe often embedded in their structure. Their structure is extremely sophisticated, while the overall particle morphology and particle size distribution are homogeneous. This study gives a first inside into the potential of these exceptional objects and may set further impulses for their utilization in specific calcite particle applications.
合成方解石（CaCO₃）颗粒在广泛的应用中被发现。由石灰石或沉淀法生产的颗粒几何形状多样，但仅限于基本形状。微藻产生微结构的方解石薄片，称为颗石藻。本文介绍了一项以应用为导向的研究结果，其中包括方解石行业用于颗粒评估的特征值。结果表明，颗石藻与迄今为止生产的所有工业颗粒都有显著差异。颗石藻是多孔颗粒，主要由碳酸钙组成，其结构中还常常嵌入镁、硅、锶和铁等其他元素。它们的结构极其复杂，而整体颗粒形态和粒度分布是均匀的。这项研究首次深入了解了这些特殊物体的潜力，并可能为它们在特定方解石颗粒应用中的利用提供进一步的推动。
