Abstract:

Flares composed of magnesium, sodium nitrate, calcium nitrate, and boron in varying ratios were prepared and tested. Luminous efficiencies, spectral power curves, and color data are presented for various formulas. Although no improvements in luminous efficiency were observed, significantly higher luminous intensity was observed in some cases when magnesium-calcium nitrate-sodium nitrate were compared with standard magnesium-sodium nitrate formulas. The dominant wavelength and excitation purity were essentially the same in all cases except when pure calcium nitrate-magnesium formulas were used. A detailed analysis of the visible spectra from magnesium-calcium nitrate and magnesium-calcium nitrate-boron flares is given.
