Abstract

Barium fluoride is used commercially in combination with other fluorides for arc welding, electrode fluxes, and in the manufacture of fluorophosphate glasses and infrared transmitting windows. Properties and preparation methods are given.

Boron trifluoride is widely used as an acid catalyst, especially for the production of petroleum and polymer products, such as in the manufacture of synthetic lubricants and in the preparation of hydrocarbon resins. Boron trifluoride is also finding increased use as a chemical reagent in the synthesis of boron-containing materials of various types.

Reactions of boron trifluoride are outlined. The types of complexes formed between boron trifluoride and oxygen-containing compounds, as well as other complexing agents, are discussed. Methods of handling boron trifluoride are described.
