Abstract
MAX phases are widely renowned for incorporating metallic and ceramic properties into a single compound but lack high degrees of porosity. Using a sol–gel chemistry technique, known as a polymer type II complex method, more flexibility of the shape, morphology, microstructure, and porosity is achieved while simultaneously synthesizing the MAX phase. This sol–gel chemistry technique demonstrates a signficant departure from traditional solid state synthetic methods. Temperature profiles in this study allowed insights into the influence of furnace and microwave heating on the resulting products. The carbonaceous Cr2GaC spheres were identified to exhibit type IV isotherm behavior and a hysteresis type of H2(a). Micropore surface areas ranged from 220–416 m2 g−1 and the maximum BET specific surface area was 616 m2 g−1.
