WebThe most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used.This can produce ice crystals at higher temperatures than silver iodide. After promising research, the use of hygroscopic materials, such as table salt, is becoming more popular. Webseeded clouds versus non-seeded clouds (Bigg 1997, Mather et al. 1997, Silverman 2000, WMO 2000. Bruintjes et al. 2001). In particular, they found that seeded clouds produced precipitation over a longer period than the unseeded cases, rather than producing more intense rainfall. The results of hygroscopic seeding are highly
