Performance Characteristics of High Temperature Gas-Fired Mantle Systems.
Abstract
The work covered in the report is a continuation of that performed under a previous effort. The performance characteristics of various Welsbach mantle compositions were obtained at high temperature by heating with a double vortex combustor. It was found that the urania-thoria system proved to be a more efficient radiator in the visible spectrum than the standard ceria-thoria composition. It was also found that hafnia is an efficient radiator material. Erbia and ytterbia were found to be as resistant to thermal shock, in mantle form, as thoria. Thermal emission spectra of these materials make them appear to be promising materials in laser pumping. The cyanogen-oxygen-boron trichloride system was studied briefly and it was found that the candlepower output of mantles could be increased at about threefold by the addition of boron trichloride to the cyanogen-oxygen flame.
