Magnesium  Fluoride  Physical and Chemical Properties:

It is a tasteless, colorless cubic crystal or powder with relative density of 3.148, mp 1261°C,bp 2239°C.

· It is soluble in nitric acid, slightly soluble in diluted acid, insoluble in water and alcohol.

· It appears a weak violet fluorescence when heated under electric arc light, its crystal has upstanding polarization, and so it is fairly suitable for ultraviolet spectrum and infrared spectrum.

· It is toxic.
