Seven different types of nanocrystals were used as additives in aluminosilicate bricks to determine if this is a valid method of decreasing the thermal diffusivity of the bricks for use as plant coating in the iron and steel industries. Each type of nanocrystal was added in concentration percentages of 0.5, 1, and 2 wt. % to determine the effect of concentration on thermal transport and physical properties. It was found that all of the ...
A series of Bi(2-x)Sb(x)Te3 powders were prepared via hydrothermal methods by varying x (x=1.45, 1.50, 1.55, 1.56). These powders were then heavily characterized by XRD, EDS, ICP-AES, TEM, SEM and the TPS technique. A low thermal conductivity was desired, so as to give the highest thermoelectric figure of merit (ZT). It was determined that the highest figure of merit was obtained when x=1.55, which resulted in a value of 1.65 ...
Li2TiO3 single crystals were grown using the flux method. These crystals were then characterized by the TPS method for thermal conductivity and a variety of other methods in order to determine the density and composition of the crystals....
