抄録

A tantalum(V) nitride (Ta₃N₅)-containing powder for non-toxic red pigments was prepared by heat-treatment for the mixed powders of tantalum(V) oxide (Ta₂O₅), aluminum nitride and potassium fluoride in nitrogen atmosphere without flowing ammonia. The foreign ions of K⁺ and Al³⁺ were incorporated into Ta₃N₅ in the synthetic process. The incorporation of the ions had an influence on the hue of Ta₃N₅. It can coordinate a reddish color of Ta₃N₅ pigments.
