General Description
An odorless white solid or powder. mp: 1291°C. Density: 2.95 g/cm3. Dust irritates the eyes and skin; inhaled dust irritates the nose, mouth and lungs. Insoluble in water. Synthesized by fusion of sodium fluoride and aluminum fluoride as a electrolyte in the reduction of alumina to aluminum metal. Occurs in nature as the mineral cryolite. Aqueous suspensions of powdered sodium aluminum fluoride are used as insecticides.
