Manganese fluoride Usage And Synthesis

Chemical Properties

Rose-colored, square prisms. Solubility in water 1.06g./100ml. Soluble in dilute hydrofluoric acid, readily soluble in concentrated hydrochloric and nitric acids.

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.

Safety Profile

Poison by subcutaneous route. When heated to decomposition it emits toxic fumes of F-. See also MANGANESE COMPOUNDS and FLUORIDES.
