Diborane is a colorless, unstable, highly toxic flammable
gas with a sickly-sweet odor. The odor is subjective and therefore
not reliable, and should not be used to detect the presence of the
gas. Diborane mixture are shipped under high pressure in steel cylinders.
Diborane can be diluted with argon, helium, hydrogen or nitrogen in
order to provide concentrations less than 100%. Using diborane in
this form can add an additional degree of control to the process,
particularly when relatively small amounts of boron are to be deposited.
Mixtures are analyzed prior to shipment to ensure that the concentration
is in the range requested. Diborane mixtures are prepared as ordered.
Concentrations other than those listed below are available upon request.
