Si-SiC composite foams were prepared using tannin-based foams as templates. The foams were prepared by four different methods for the determination of which method would best produce a foam with a pore size under 200 µm. The foam samples were characterized by SEM, XRD, and Raman spectroscopy, and the thermal conductivity of one of the foams was investigated by the transient plane source method. It was found that direct infiltration of ...
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 ...
