Abstract: Binary pyrolants based on ytterbium and either polytetrafluoroethylene or hexachloroethane yield a broad stable combustion regime with intense luminous flames. Combustion temperatures have been determined spectroscopically for both pyrolant types. The temperature correlates with the burn rate of the pyrolant. The UV-Vis spectra of the fuel rich pyrolants have been measured and were converted into x,y-color values in the 1931 CIE color diagram. The color obtained with both pyrolant types produce shorter dominant wavelength emission and higher saturation than common BaCl BO2 emitters.

Keywords: Ytterbium, Polytetrafluoroethylene, PTFE, Pyrolant, Burn rate, Combustion Temperature
