The Effect Of Antimony And Cobalt On The Current Efficiency And The Grain Orientation Of Deposits During The Electrolysis Of A Zinc Sulfate Solution, Samuel A. Worcester
The Effect Of Antimony And Cobalt On The Current Efficiency And The Grain Orientation Of Deposits During The Electrolysis Of A Zinc Sulfate Solution, Samuel A. Worcester
Bachelors Theses and Reports, 1928 - 1970
Preparation of solutions and apparatus and experimental procedure was described. The effect of antimony and cobalt in a zinc sulfate electrolyte upon current efficiency with increasing time was determined by the hydrogen evolution method. The degree of preferred orientation of grains in the electrodeposits was determined by the reflection method of X-ray diffraction.
Artificial Rhodonite: It's Synthesis And X-Ray Diffraction Powder Pattern, Frank E. Jeniker
Artificial Rhodonite: It's Synthesis And X-Ray Diffraction Powder Pattern, Frank E. Jeniker
Bachelors Theses and Reports, 1928 - 1970
This report presents the investigation of three methods of synthesizing artificial rhodonite; fusion of silica and manganese dioxide, prolonged sintering of the compact of manganous carbonate and silica at below liquidus temperatures, and the precipitation by reaction of salts in an aqueous solution followed by sintering. In each case the rhodonitic product was of less than desired purity, containing varying amounts of silica, tephroite, and higher valence oxidized manganese forms, as well as aluminum.
