Mg3Pt2: Anionic Chains in a Eu3Ga2-Type Structure

“… 19 Mg is a chemically reactive element, and it easily interacts with the alloying constituents, giving rise to the formation of intermetallic compounds. 20 − 23 Besides their technological importance, exploring intermetallic compounds of Mg, their phase equilibria, and their structure–property relationships has been of general interest to the solid-state physics and chemistry community. 21 , 24 − 37 The high affinity of Mg to Pt metals 38 gives rise to a very variable structural chemistry, 39 , 40 as has been elaborated for the Mg–Rh, 41 − 46 Mg–Ir, 46 − 53 and several Mg–Pd 54 − 63 systems.…”

“…Light-weight Mg alloys with improved mechanical properties are therefore a scientific topic for applied and pure material sciences. − Alloying elements like aluminum, copper, and zinc, together with other transition metals or rare-earth metals, are added to Mg to improve its strength, ductility, and creep and corrosion resistance. , Besides the strong focus on structural applications, current research on Mg alloys as hydrogen-storage materials − and their application as biomaterials should also be strongly emphasized. , Pt-rich alkaline-earth-metal alloys currently attract interest as electrocatalytic materials for the oxygen reduction reaction in fuel cells. , We also note that the use of Mg in extracting Pt from electronic or used-catalysator scrap has also been envisioned .

For the Mg–Pt system, no phase diagram is reported in the literature; however, several intermetallic phases have already been described.…”

Theoretical Investigation of Thermodynamic Properties of the Al–Si–Fe Ternary Alloy

“…The Miedema model has been widely used in the study of the thermodynamic properties of binary alloys due to its simple calculation and high accuracy. , For ternary alloys, it is mainly based on the thermodynamic properties of binary alloy systems through geometric model extrapolation. Zhang et al calculated the mixing enthalpy of the Al–Cu–Re ternary alloy system in the whole composition range by using the Miedema theory and the geometric extrapolation model and used it for ternary amorphous composition design and related performance research.…”

Magnesium: properties and rich chemistry for new material synthesis and energy applications

“…Mg alloys have attracted attention as electrocatalytic materials for fuel cells and water electrolyzers, because of their ability to form robust intermetallic compounds. 13,14 In particular, Mg has been found to have a high affinity for forming alloys with platinum group metals (PGMs) such as Pt, 1 Rh, 15 Ir, 16 and Pd. 17 These alloys can greatly decrease the reaction barriers typically encountered in the oxygen reduction reaction (ORR), formic acid oxidation (FAO), oxygen evolution reaction (OER), and ethanol oxidation reaction (EOR).…”
