  Bismuth telluride(Bi2Te3)based compounds are known as the best commercially used thermoelectric(TE)materials at ambient temperature from 300 K to 500 K,which can achieve the direct conversion between electrical energy and thermal energy.In the present work,a new consolidation technique of microwave activated hot pressing(MAHP)was recommended and some fine-grained and highly densified p-type Bi0.4Sb1.6Te3 and n-type Bi2Te2.85Se0.15 compounds were prepared via mechanical alloying(MA)combining with MAHP process for the first time.Based on the microwave pressureless sintering technique,the MAHP was developed independently in our lab.
