INVESTIGATION OF THE THERMAL-CONDUCTIVITY OF SELECTED COMPOUNDS OF LANTHANUM, SAMARIUM AND EUROPIUM

As part of the development of rare earth based ceramic materials for a variety of applications, the thermal conductivities of lanthanum alum inate, samarium zirconate and europium zirconate were investigated, em ploying the laser flash technique and covering a temperature range fro m 650-1400 K. Based on the variation of the thermal resistivity as a f unction of temperature, the heat transport behaviour of these material s was briefly examined. (C) 1998 Elsevier Science S.A.
