Preparation Of Elemental Boron And Measurement Of Its Emittance At Incandescent Temperatures, Claude P. Talley
Preparation Of Elemental Boron And Measurement Of Its Emittance At Incandescent Temperatures, Claude P. Talley
Master's Theses
The normal spectral emittance at 0. 65 microns of elemental boron specimens was measured at incandescent temperatures by the hollow-tube method, This was made possible by depositing boron onto thin-walled hollow tubes of graphite and molybdenum. An approximate value of the total hemispherical emittance for boron was also obtained. The deposition of boron was accomplished by chemical vapor plating with boron tribromide and hydrogen. The boron produced was characterized in several ways.
