Beryllium Fluoride

Beryllium Fluoride is the inorganic compound. Beryllium fluoride can be made by the thermolysis of ammonium beryllium fluoride, (NH4)2BeF4.Beryllium Fluoride in the form of fluoroberyllate glass it has the lowest refractive index for a solid at room temperature of 1.275. It dispersive power is the lowest for a solid at 0.0093. It is used in biochemistry, particularly protein crystallography as a mimic of phosphate. Beryllium Fluoride forms a basic constituent of the preferred fluoride salt mixture used in liquid-fluoride nuclear reactors.

Beryllium Oxide

Beryllium oxide is an inorganic compound. It is an electrical insulator with a thermal conductivity higher than any other non-metal except diamond, and actually exceeds that of some metals. Its high melting point leads to its use as a refractory. It is used in rocket engines. It is used as a filler in some thermal interface materials such as thermal grease. Some power semiconductor devices have used beryllium oxide ceramic between the silicon chip and the metal mounting base of the package in order to achieve a lower value of thermal resistance than for a similar construction made with aluminium oxide. It is also used as a structural ceramic for high-performance microwave devices, vacuum tubes, magnetrons, and gas lasers.

Biphenyl is an aromatic hydrocarbon. It has a distinctively pleasant smell. It is notable as a starting material for the production of polychlorinated biphenyls, which were once widely used as dielectric fluids and heat transfer agents. Biphenyl is also an intermediate for the production of a host of other organic compounds such as emulsifiers, optical brighteners, crop protection products, and plastics.
