Specification
The Cadmium fluoride, with the CAS registry number 7790-79-6, has the systematic name of cadmium difluoride and EINECS registry number 232-222-0. And the molecular formula of this chemical is CdF2. It is a kind of white powder, and belongs to the following product categories: Cadmium Salts; Cadmium Metal and Ceramic Science; Catalysis and Inorganic Chemistry; Chemical Synthesis; Salts.
The physical properties of Cadmium fluoride are as following: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0 ; (4) Polar Surface Area: 0 Å2; (5)Enthalpy of Vaporization: 25.54 kJ/mol; (6)Boiling Point: 19.5 °C at 760 mmHg; (7)Vapour Pressure: 922 mmHg at 25°C.
Preparation of Cadmium fluoride: It can be prepared by the reaction of gaseous fluorine or hydrogen fluoride with cadmium metal or its salts. It can also be prepared by dissolving cadmium carbonate in 40% hydrofluoric acid solution, evaporating the solution and drying in a vacuum at 150 °C. And it also can be obtained by mixing cadmium chloride and ammonium fluoride solutions, followed by crystallization.
Applications of Cadmium fluoride: It is used in oxygen-sensitive applications such as the production of metallic alloys, and it is also used in limited medical treatment protocols. In addition, it can be used in synthetic organic chemistry.
You should be cautious while dealing with this chemical. It is toxic if swallowed, and very toxic by inhalation.
