"A. The Problem.

The purpose of this investigation was to form by ceramic processes a number of compositions in the ternary system NaNbO₃ - BaSnO₃ - BaTiO₃, to determine certain dielectric properties of these, to study them by means or x-ray diffraction, and to determine the extent or correlation possible between the compositional variation of dielectric properties and the x-ray results.

Compositions investigated contained 50 mole percent or less BaSnO₃. Materials and methods of forming were chosen with the intent that the final bodies should be pure oxide compositions as represented in the ternary …

Preparation And Separation Of Metallic Chlorides, Norbert Felix Neumann

Doctoral Dissertations

"The use of chlorine and chlorine compounds as metallurgical reagents has long been known to the metallurgical industry. Recent developments in corrosion resistant metals and alloys as well as new equipment and techniques have led to a revival of chlorine processes. Many of the objections to the use of chlorine in metallurgical operations have been overcome and many are being reconsidered, as evidenced by the new processes in which chlorine and chlorides are the primary reagents. The Betterton process employs chlorine or lead chloride for the dezincing of lead. Ductile zirconium and titanium have been made by reducing their chlorides …
