The inorganic substance strontium fluoride has the formula SrF2. Due to its special qualities, it is a crystalline solid that is employed in a variety of applications. Strontium ions (Sr2+) and fluoride ions (F-) combine to form this type of substance. It belongs to the category of substances known as ions, in which electrostatic forces cause positively charged ions (cations) to be drawn to negatively charged ions (anions). Strontium fluoride produces colourless crystals with a cubic crystal shape. With a density of roughly 4.24 grammes per cubic centimetre, it has a high melting point of roughly 1,470 degrees Celsius.
