A Study Of The Curcumin Method For Boron Determination, James Edward Hardcastle
A Study Of The Curcumin Method For Boron Determination, James Edward Hardcastle
Master's Theses
The purpose of the research project, of which this thesis is a partial report, was two fold: first, to develop a method for determining small quantities of boron, and second, to develop a rapid field test for the determination of atmospheric boron. A literature survey revealed that the curcumin method is the most sensitive colorimetric method presently available for boron determination. Also, the curcumin paper test should be readily adapted to the determination of atmospheric boron.
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.
