Differential Thermal Study of Pyrosynthesis

Edgar M. Bollin 1, James A. Dunne 1, and Paul F. Kerr 1

1 Columbia University, New York

Equipment is described which provides a thermal record of the synthesis of sulfides and related minerals contained in easily constructed tubular glass vials. As an example, a temperature curve for the synthesis of galena (PbS) is given. Similarly derived temperatures of formation for eight other synthetic sulfides and selenides are reported.
