is produced by reacting together one of the following sets of ingredients.in each case the reaction requires elevated temperatures.
Finely divided carbon plus boric acid and chlorineApplication
It is used as a chemical reagent in the pharmaceutical industry.
It is used as a source of boron for p-type doping silicon by thermal diffusion or ion implantation. It is also used for dry plasma etching of aluminium and its alloys
It is used as a carrier gas, as a catalyst in the organic reaction, for manufacturing of electrical resistors.
It may be used in the production of optical fibre.
Liquefied gas, decompose in water to hydrogen chloride and boric acid forms white fumes in humid air pungent odour highly corrosive.
Highly toxic, attack the eyes and mucous membranes, can cause lung damage.
