Pinkish powder | [Uses]
Manganese(II) fluoride is used in the manufacture of special kinds of?glass?and?lasers. | [Preparation]
Manganese carbonate is added to an excess of 40% hydrofluoric
acid solution contained in a platinum or lead dish. The pale-red
solution of manganese fluoride is then decanted and dried at 110°C. |
