%X Thermoelectric polycrystal ceramic materials were prepared by a new ceramictechnology.The specimens were sintered by solid reaction in a sealed evacuated quartz tube.The new ceramic cooling materials have a inhomogeneous structure, but higher mechanicalstrength and the thermoelectric properies.The P-type 72%Sb_2Te_3+25%Bi_2Te_3+3%Sb_2Se_3doped and N-type 90%Bi_2Te_3+5%Sb_2Te_3+5%Sb_2Se_3 doped were studied.High qualityBi_2Te_3-Sb_2Te_3-Sb_2Se_3 pseudo-ternary solid solution can be prepared under optimum technol-ogy conditions.The polycrystal ceramic materials have a obvious layered structure,but sinter-ing is closer.
