OccurrenceBorax pentahydrate occurs in nature as mineral tincalconite, formed by dehydration of borax. It has several industrial applications, mostly the same as its decahydrate. The pentahydrate is used in the manufacture of borosilicate glass. It also is used in cleaning agents; ceramic glaze; adhesives; cosmetics; antifreeze; and herbicide formulations. It is added to fertilizers to provide boron as a nutrient to the plants.
Production MethodsBorax pentahydrate is produced from various sodium borate and magnesium borate ores. In the United States, it is produced from dry lake brines, colemanite and tincal. It is commercially produced along with the decahydrate. The production processes are similar to decahydrate (see Borax decahydrate).
