BISMUTH OXYBROMIDE Chemical Properties,Usage,Production

Chemical Properties

colorless crystal(s) or amorphous powder(s); used in manufacture of dry cell cathodes [MER06] [CRC10]

Uses

manufacture of dry cell cathodes.

Production Methods

A solution of 3 g of Bi2O3 in 50 ml of hydrobromic acid (d 1.38) is heated to boiling. It is then diluted with 1.5-1.6 litres of boiling water, and boiling is continued until the initial precipitate redissolves. The BiOBr crystallizes on cooling in ice. It is washed with dilute hydrobromic acid and then with pure water.
