Abstract:

The report discusses the ignition delay times, burn times or rates and combustion efficiencies of doped and undoped boron and compound of boron with aluminum, magnesium, and lithium. A literature survey has been conducted for information on the properties and combustion of aluminum, magnesium and lithium borides. An optical burner apparatus has been modified and calibrated for the present investigation. Eight borides have been obtained or prepared for this program, were analyzed for purity on the basis of chemical, spectrographic, or X-ray data.
