Zusammenfassung:	Abstract Methods for making ceramic powders are provided. In some embodiments, a method for forming a ceramic powder comprising: adding a sufficient amount of additives to a plurality of reagents to form a precursor mixture so that when the precursor mixture is carbothermically reacted the precursor mixture forms a ceramic powder, wherein the additive includes at least one of an oxide, a salt, a pure metal or an alloy of elements ranging from atomic numbers 21 through 30, 39 through 51, and 57 through 77 and combinations thereof; and carbothermically reacting the precursor mixture to form a ceramic powder, wherein the ceramic powder comprises: a) a morphology selected from the group consisting of irregular, equiaxed, plate-like, and combinations thereof, and b) a particle size distribution selected from the group consisting of fine, intermediate, coarse, and combinations thereof.
