Abstract

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.
