โœฆ Synopsis

Samples of (Ag + Hg) amalgam and of dental amalgam have been prepared and stored a t temperatures of 23, 37.5, and 60ยฐC for various lengths of time up to 10 years. X-ray diffraction and optical microscopy have been employed to determine the approximate increase in the P(Ag-Hg) phase as a resiilt of the y .-f p transition in the Ag-Hg system. Data are presented to show that the transition occurs in both systems but much less rapidly in dental amalgam. Increases in storage temperature increase the rate of the transition in both systems.

The integrated intensities of certain reflections of the 7 , yl, and y2 phase have been determined as a function of the mercury content of 6 amalgams after annealing for 20 hr at 37ยฐC. This dependency could be described satisfactorily by means of the regression model: Here I , is the integrated pea

Superconducting cuprates with the general stoichiometry (Tl, Hg) 2 (Ba, Sr) (Sr, Ca) 1 Cu 2 O 8ุŠ were examined by X-ray powder di4raction, including Rietveld re5nement calculations. The aim was to obtain structural properties that could be related to the diamagnetic transition onset temperature (T c
