from 0.17 to 0.34 at 875 K for Co0.95Zn0.05SbS0.85Se0.15 sample, due to the noticeable decrease in the lattice thermal conductivity by introducing point defect, which is further confirmed by an analysis based on the Debye-CallawayKlemens model. Meanwhile, the thermoelectric power factor is maintained at high temperatures. This work highlights the important role of point defect in improving......

and development of gelcasting techniques are reviewed. The principles and processes of this forming technology are discussed. Gel systems are summed up and divided into synthetic and natural gel systems according to the source of gel systems. Applications are commented. Finally, the problems and development of gelcasting technology are also pointed out and analyzed. Key words: gelcasting; forming......
curves were given out. At last, through the fitting of the simulation test results, the math models for the area of fishtail defect changing with the presented factors were received. The experimental results show that the accuracy of the prediction for the fishtail shapes is more than 95%. With the application of the prediction for the fishtail shapes and the area of the fishtail defect, the loss......
