Ceramics are an important class of materials with widespread applications because their high thermal, mechanical, and chemical stability. Computational predictions based on first principles methods can be a valuable tool in accelerating discovery to develop improved ceramics. It is essential experimentally confirm the material properties such predictions. However, screening rates limited by long processing times poor compositional control from volatile element loss conventional ceramic...
