✦ Synopsis

The burning velocity of lean premixed disilane-oxygen-nitrogen flames has been measured at disilane and oxygen concentrations ranging from 0.55% to 1.05% and from 2% to 21%, respectively. The general trend of burning velocities has been found to be very similar to those for silane flames. However, a few different points have also been noted; above stoichiometric concentrations part of the oxygen remains unconsumed through the reaction zone, though disilane is consumed almost completely. Even in oxygen-rich flames, oxygen consumption is always less than is required for complete combustion of disilane. Further, the general trend in hydrogen production is remarkably different from that of silane flames. A large number of compounds containing Sill and Sill2 bonds are found in the solid products. The difference between disilane and silane combustion seems to be caused by the difference in the flame temperature.
