The method comprises mixing one or more lanthanide chromite ceramics with one or more sintering aids, and sintering the mixture. The one or more lanthanide chromite ceramics are represented by the formula (Ln1-xAEx)zCr1-yByO3-δ, wherein Ln is a lanthanide element or yttrium, AE is one or more alkaline earth elements, B is one or more transition metals, x is a value less than 1, y is a value less than or equal to 0.5, and z is a value from 0.8 to 1.2. The sintering aids comprise one or more spinel oxides. The one or more spinel oxides are represented by the formula AB2O4 or A2BO4 wherein A and B are cationic materials having an affinity for B-site occupancy in a lanthanide chromite ceramic structure, e.g., ZnMn2O4, MgMn2O4, MnMn2O4 and CoMn2O4. This disclosure also relates in part to products, e.g., dense ceramic structures produced by the above method.
