Is the ultra-fast transformation of bismuth non-thermal? - arXiv

WebIn one such instance n-type bismuth telluride was shown to have an improved Seebeck coefficient (voltage per unit temperature difference) of −287 μV/K at 54 °C, [6] However, one must realize that Seebeck coefficient and electrical conductivity have a tradeoff: a higher Seebeck coefficient results in decreased carrier concentration and decreased … WebIt has a melting point of approximately 70 °C (158 °F). [3] [4] Applications [ edit] Wood's metal Wood's metal is useful as a low-melting solder, low-temperature casting metal, high-temperature coupling fluid in heat baths, and as a fire-melted valve element in fire sprinkler systems in buildings. bdi ruotsiksi
