大多数被认为可能作为云催化冰核的物质是具有与冰相似晶格参数的六方结构的无机化合物。使用有机化合物作为冰核的可能性尚未被探索。在对水不溶性有机化合物的研究中，30种对称性主要为单斜晶系或斜方晶系的类固醇中有7种被发现与银一样能有效地使冰成核。发现一类能够充当冰核的有机材料似乎是新颖的。
MOST substances suggested as possible ice nuclei for cloud seeding are inorganic compounds of hexagonal structure with lattice parameters similar to those of ice. The possibility of using organic compounds as ice nuclei has not yet been explored. During an investigation of water-insoluble organic compounds, seven out of thirty steroids examined, the symmetry of which was mainly monoclinic or orthorhombic, were found to nucleate ice almost as effectively as silver iodide. The discovery of a class of organic materials capable of acting as ice nuclei appears to be novel.
