A kind of p- type segmented Bi2 Te3/ CoSb3 thermoelectric material was prepared by spark plasma sintering( SPS ). When the segmented materials were used at the
SnO2-glaze composites were prepared by Sb-doped SnO2 and SiO2- CaO-Al2 O3- B2 O3 glaze. The composites changed from an electrical insulator to a conductor as th
