“…As a result of graphene addition, ZT was found to increase in the composite samples compared to pristine Bi 2 Te 2.7 Se 0.3 . Bi 0.3 Sb 1.7 Te 3.0, thermoelectric compound was fabricated using an yttrium vessel and stainless steel vessel by Mongkol et al 149 The mixture milled at 150 rpm with an yttrium vessel was found to have a higher ZT value than the compound milled in a stainless steel vessel by a factor of 1.7 at 500 K. The electrical conductivity, Seebeck coefficient, and thermal conductivity of the bismuth antimony telluride were 4.6 × 10 4 S/m, 295 µV/k, and 0.94 W/mK, respectively, at 500 K (Fig. 10a, b, c, and d).…”

One of the global demands of primary research objectives is to achieve human energy harvesting and self-powered wearable technologies. Bismuth chalcogenides are the trending materials for thermoelectric generators and Peltier coolers due to their notable thermoelectric figure of merit in the low- and room-temperature range. Systematic alloying of bismuth chalcogenides leads to a substantial change in their electrical and thermal transport properties. The high thermoelectric figure of merit (ZT) observed in bismuth chalcogenides is due to the rhombohedral crystal structure, lower effective mass, low thermal conductivity, and large band degeneracy. This review is aimed at identifying and quantifying different techniques for effectively improving the thermoelectric properties of doped/composite bismuth chalcogenide compounds. The review also examines the various synthesis methods including ball milling (BM), spark plasma sintering (SPS), self-propagating high-temperature synthesis (SHS), soft chemical reaction, hydrothermal reaction, melt growth (MG), melt spinning (MS), sintering and consolidated synthesis, and hot extrusion, with their respective figures of merit. Since device modification is a challenging task, this report reviews the present research on bismuth chalcogenide alloys to benchmark future development using various techniques. Graphical Abstract

“…One of the most commonly used MA methods is that of the planetary ball milling (PBM) process [7][8][9][10][11], and it has significant advantages over other conventional methods (mixer mills, stirred mills, etc.). It is effective for wet and dry grinding processes due to the high mechanical stresses reached during the operation, and submicron and nanosized particles can be achieved with the proper milling balls and milling conditions.…”

This study investigates the effects of continuous and in-steps mechanical alloying of a bismuth antimony telluride powder mixture (Bi0.4Sb1.6Te3.0) via the mechanical planetary ball milling (PBM) process as a function of milling time and powder mixture amount. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the phase, composition, and morphology of the alloy. The alloyed powder with the optimum PBM conditions was then hot pressed (HP), and its thermoelectric properties were further investigated. The results on the alloying of the powder mixture showed that due to the high agglomeration tendency of BST during the PBM process, a significant deviation occurs in the development of a single-phase state over time when the powder mixture is milled continuously and in-steps. ’In-steps’ refers to the procedure of interrupting the PBM process and detaching the agglomerated powder adhering to the inner walls of the vessel. This task was repeated every hour and a half of the PBM process for a total of 12 h, and the results were compared with those of the 12 h continuous PBM process of the same mixture. In addition, the procedure was repeated with different amounts of mixture (100 g and 150 g) to determine the most efficient method of producing the material as a function of time. As for the thermoelectric profile of the powder, the data showed results in direct agreement with those in the literature.
