ramp-rate) using spark plasma sintering (SPS). The eﬀects of SPS conditions on the anisotropic thermoelectric properties and microstructure evolutions were systematically investigated. The change of sintering temperature showed stronger inﬂuence than other sintering parameters to the resulting thermoelectric properties.

However, the DTA, probably due to insufficient sensitivity to small concentrations of impurities, has not shown any effect of free antimony separation. The composition of the gas–vapour phase in the synthesis does not actually depend on the antimony telluride to antimony selenide ratio. Tellurium is the basic component of the gas–vapour phase.
Apr 21, 2018· Naturally occurring tellurium is more rare than gold, and as difficult to find in the earth's crust as any platinum group metal (PGM), but due to its existence within extractable copper ore bodies and its limited number of end-uses tellurium's price is much lower than any precious metal.
The room temperature lattice thermal conductivity for unintentionally doped tellurium is ∼1.6 Wm −1 K −1, which is comparable with conventional thermoelectric lead chalcogenides 21,50,53,54 and bismuth/antimony tellurides 52,55, but significantly lower than those of group IV or group III–V semiconudctors 38,56.
Antimony telluride is an inorganic compound with the chemical formula Sb 2 Te 3. It is a grey crystalline solid with layered structure. Layers consist of two atomic sheets of antimony and three atomic sheets of tellurium and are held together by weak van der Waals forces.
Antimony: Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms. It is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite.
Bismuth telluride (Bi 2 Te 3) and antimony telluride (Sb 2 Te 3), displaying the highest thermoelectric power at room temperature, are also known as topological insulators (TIs) whose electronic structures are modified by electronic confinements and strong spin–orbit interaction in a-few-monolayers thickness regime, thus possibly providing ...

Antimony telluride Wikipedia. Antimony telluride is an inorganic compound with the chemical formula Sb 2 Te 3. It is a grey crystalline solid with layered structure. Layers consist of two atomic sheets of antimony and three atomic sheets of tellurium and are held together by weak van der Waals forces.
Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in native form as elemental crystals.
Tellurium was discovered in 1783 by Franz Joseph Müller von Reichenstein at Sibiu, Romania. He became intrigued by ore from a mine near Zalatna which had a metallic sheen and which he suspected was native antimony or bismuth. (It was actually gold telluride, AuTe 2.) Preliminary investigation showed neither antimony nor bismuth to be present.
TELLURIUM is attacked by chlorine fluoride with incandescence. When tellurium and potassium are warmed in an atmosphere of hydrogen, combination occurs with incandescence [Mellor 11:40. 1946-47]. Burning tellurium produces toxic tellurium oxide gas. Avoid solid sodium, halogens, interhalogens, metals, hexalithium disilicide.
Tellurium is a p-type semiconductor, and shows greater conductivity in certain directions, depending on alignment of the atoms. Many tellurium compounds exhibit photoconductivity--their conductivity increases slightly with exposure to light--which makes many tellurides candidates for …
