The synthesized Bi 0.5 Sb 1.5 Te 3 powders were mixed with Al 2 O 3 nanoparticles by a high-energy ball milling process (Planetary Milling Machine, Fritsch) in a hexane solvent. The Al 2 O 3 /BST composite powders were consolidated by a spark plasma sintering process (SPS, Weltech Co., WL-15-400, Republic of Korea) at 350°C for 10 min [ 12 ].

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
