Mineral dust appears a promising source of sublimation nuclei. Dust produced by the disintegration of rocks and blown to fairly high levels is a probable source of supply. Sand from desert regions is another possibility. It is likely that both the mineral dust and the sand contain suitable minerals, such as quartz, which have a hexagonal crystal structure. 5, record 1, English, - mineral%20dust

Chlorine dioxide manufacture. Chlorine dioxide is an explosive gas and cannot be prepared safely in undiluted form nor can it be liquified for transport and storage, therefore it must be manufactured on site. The processes that have been developed which generate chlorine dioxide in dilute aqueous solution by reducing sodium chlorate in a strong acid solution with a reducing agent usually sulphur dioxide, methanol, sodium/hydrogen chloride and lastly hydrogen peroxide. 1, record 5, English, - chlorine%20dioxide%20manufacture
