Preparation and Characterization of Mg–Al–B Alloy (Mg<sub>0.5</sub>Al<sub>0.5</sub>B<sub>2</sub>) Via High-Temperature Sintering

Boron and its alloys have long been explored as potential fuel and increasingly replace pure aluminum powder in high-energy formulations. The ignition and burning properties of boron can be improved by making boron alloys. In this study, an Mg–Al–B alloy was synthesized from magnesium, aluminum and...

The ignition and burning properties of boron can be improved by making boron alloys.

The phase composition, micromorphology and the bonding forms of elements of the synthesized samples were studied using XRD, SEM and XPS.

The influence of the sintering temperature on the synthesis reaction of Mg<sub>0.5</sub>Al<sub>0.5</sub>B<sub>2</sub> is very important, but holding time has little effect on it. With the increase of sintering temperature, the content of the Mg<sub>0.5</sub>Al<sub>0.5</sub>B<sub>2</sub> phase gradually increases, and the phase content of residual metal gradually decreases. The phase and morphology analyses show that the optimum sintering temperature is 1000 °C with a minimum holding time of 0.5 h. It is expected to be used in gunpowder, propellant, explosives and pyrotechnics with improved characteristics.https://www.mdpi.com/1996-1944/14/13/3608metal fuelMg<sub>0.5</sub>Al<sub>0.5</sub>B<sub>2</sub> alloysintering temperatureholding time
