Boron Trifluoride (BF3)
Boron Trifluoride is a highly toxic, colorless, nonflammable compressed
gas with a pugnent odor. Fumes strongly in moist air. Boron has properties
which are borderline between metals and non-metals. It is a semiconductor
rather than a metallic conductor. Chemically it is more related to silicon
than to aluminum, gallium, indium, and thallium. Fluorine is the most electronegative
and reactive of all elements. It is a pale yellow, corrosive gas, which
reacts with practically all organic and inorganic substances. Boron Trifluoride
is used extensively in the semiconductor field.
