COMBUSTION OF ELEMENTAL BORON
Abstract
IT WAS CONFIRMED THAT BF is the species evolved from the surface of a heated B rod exposed to F gas inside a mass spectrometer. Evidence indicated that the rate of formation of BF is only slightly dependent on temperature above 1200 K. Preliminary experiments in a microbalance apparatus show no detectable reaction between a high-purity polycrystalline B rod at ambient temperature and F gas at 1 to 200 micron Hg pressure. However, a B rod heated to about 600 K in an image furnace gives a reaction rate of about 10 to the 16th power molecules/sq cm-sec at a F pressure of 1 micron Hg. This value is subject to an upward revision since it corresponds to approximately total consumption of the F at the flow rates possible with the equipment.
