40 bi sn phase diagram

Experimental studies on polyamorphism are often conducted on low-melting-point metals such as Ga, Bi, Rb, Cs, and Sn due to their easily accessible liquid phases at high pressure and their peculiar short-range liquid structures. [14, 15, 18-20] The Ga 85.8 In 14.2 (GaIn) eutectic alloy (T m = 288.3 K) has been recently investigated in this context. An ideal Weyl semimetal with high tunability is an undoubtedly important platform for realizing and manipulating exotic quantum properties of topological semimetals. Currently, all the existing nonmagnetic Weyl semimetals are not ideal and out of external control, namely, no couplings to an order parameter. In this work, we report with a topological phase transition diagram the successful ...

The calculation of k is shown in the Bi-Sn phase diagram below: In most cases, the liquidus and solidus are not straight lines, but they are often close enough that we can assume that k is independent of temperature. Also, it is often the case that k is less than one, so that the solid forming is of a higher purity than the liquid. previous | next
