Synthesis of SnSb2Te4 Microplatelets by High-energy Ball Milling [PDF]

open access: yesMaterials Research, 2015
In this work we demonstrate that high-energy ball milling process can be used to synthesize SnSb2Te4 without surfactant and further annealing. Milling parameters such as ball to raw material ratio (5:1) and milling time (2h) were determined to be ...

Thermoelectric property studies on thallium-doped lead telluride prepared by ball milling and hot pressing [PDF]

open access: yes, 2010
Thallium doping into lead telluride has been demonstrated to increase the dimensionless thermoelectric figure-of-merit (ZT) by enhancing Seebeck coefficient due to the creation of resonant states close to Fermi level without affecting the thermal ...

In-situ synthesis of a ZrB2–based composite powder using a mechanochemical reaction for the zircon/magnesium/boron oxide/graphite system [PDF]

open access: yes, 2015
A ZrSiO4/B2O3/Mg/C system was used to synthesize a ZrB2-based composite through a high-energy ball milling process. As a result of the milling process, a mechanically induced self-sustaining reaction (MSR) was achieved in this system.
