LOW TEMPERATURE THERMAL EXPANSION OF WURTZITE-PHASES OF IIB-VIB COMPOUNDS. PART I. THERMAL EXPANSION OF ZNS, WURTZITE FROM 2 DEGREES TO 317K.
Abstract
Thermal expansion measurements of the wurtzite phase of CdS(5) and the zincblende phase of ZnS(6) have indicated that negative values of molar volume coefficients of expansion are to be expected from open structures, especially those like ZnS which have low shear moduli. In this experiment the thermal expansion of the wurtzite phase of ZnS was measured using a back reflection Debye-Scherrer X-ray camera. The minimum value of the molar volume was found to occur at 60 degrees plus or minus 5K. Experimental results indicate that retrograde behavior is found both parallel and perpendicular to the c-axis in ZnS. The total decrease in molar volume from 300K to the minimum volume obtained was approximately 0.3%. (Author)
