Characterization of Bulk Nanostructural Bi2Te3-based Material Prepared by Microwave-solvothermal Synthesis and Hot Isostatic Pressure

摘要

The bulk nanostructural Bi2Te3-based material was prepared by microwave assisted solvothermal udmethod and hot isostatic pressure. Optimal synthesis conditions of the Bi2Te3 nanopowder were found. It udwas established that hot isostatic pressing of the nanopowders at the temperature of 400 С and the pres-sures of 2, 4, 6 and 8 GPa allowed us to prepare the homogeneous and dense Bi2Te3-based material with udthe mean grain size of~50 nm. It is found that an electrical resistivity increases as the mean grain size of udthe material under study decreases.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/36382
