“…The furnace temperature was stabilized at 500°C until the oxidation time reached 300 h; at designated intervals, the samples were removed from the furnace to evaluate as the change in the weight of the samples after 300 h oxidation was minor. The results obtained from oxidation kinetic curves at 500°C as a function of time and mass change/area displayed that the rate of change of weight of high entropy silicide over the entire oxidation process was .00088 mg/cm 2 h, which was much lesser than the outcomes of pure MoSi 2 and other improvised MoSi 2 (.007, .01636364, and .3 mg/cm 2 h) from a chain of pest oxidation resistance, respectively 103–105 . The high entropy silicide weight remains stable during oxidation, thus displaying a fine pest oxidation resistance property.…”

“…To tackle this challenge, Liu et al 26 a chain of pest oxidation resistance, respectively. [103][104][105] The high entropy silicide weight remains stable during oxidation, thus displaying a fine pest oxidation resistance property. The pest phenomenon occurs when oxygen enters the material, resulting in the generation of metallic oxides, which leads to severe oxidation, resulting in the propagation of cracks and gaps in the material due to internal stress development.…”

Metal silicides and silicates belong to the silicon-based non-oxide and oxide ceramics family with exceptional properties. Silicides face fatal oxidation at low temperatures and intrinsic brittleness, whereas silicates face instability in phase at high temperatures which restricts its usage in vast engineering applications. Hence, the ceramic community introduced the concept of high entropy in metal silicides and silicates. Since 2019, high entropy silicides and silicates, a multicomponent system, have created new avenues for materials discovery and design. High entropy silicides displayed elevated properties than the traditional silicides aiming its applications in microelectronic, hightemperature oxidation resistance coatings, and structural materials. Similarly, high entropy silicates displayed improved properties than the traditional silicates making them the most promising materials for environmental and thermal barrier coating applications for hot section components in gas turbines. The review focuses on specific case studies to emphasize the latest research and developments in high entropy silicides and silicates. Synthesis approaches employed in developing high entropy silicides and silicates and their structural and microstructural outcomes are addressed. The possible application is predicted based on the overview of the properties explored to date. The review concludes with future possibilities offered by the high entropy silicides and silicates.
