摘要： Provided are a barium germanium oxide having a 3-4 eV band gap, a method for producing the same, a sintered body thereof, and a target thereof. The barium germanium oxide includes at least Ba, Ge, and O, includes a crystal represented by a general formula of ABO3 (here, A includes at least Ba and B includes at least Ge), and has a hexagonal 6H-type perovskite structure.

摘要： The present invention addresses the problem of providing a method for synthesizing hexagonal tungsten nitride by synthesizing hexagonal tungsten nitride as a main product, and of providing the hexagonal tungsten nitride. The problem is solved through use of a method for synthesizing hexagonal tungsten nitride comprising synthesizing hexagonal tungsten nitride by heating a starting material powder containing a tungsten halide and an alkali metal nitride and/or an alkaline earth metal nitride.
