Determination of boron in silicon-bearing alloys, steel, and other alloys by pyrohydrolysis and inductively-coupled argon-plasma spectroscopy.

Boron is quantitatively separated from silicon-bearing and other inorganic materials by pyrohydrolysis. Microgram amounts of boron are separated by passing oxygen-saturated steam over a sample mixed with vanadium oxide and copper oxide. The distillate is collected in dilute potassium hydroxide solution and determined by inductively-coupled argon-plasma spectroscopy.
