Ammonolysis of HTiNbO5–n-Propylamine Intercalation Compound

Abstract

The ammonolysis reaction to form (Ti,Nb)N was enhanced by the use of HTiNbO5–n-propylamine intercalation compound as a starting material and compared with that for a simple mixture of TiO2 and Nb2O5. The ammonolysis product formed at 1200 °C was a superconductor (Tc = 15 K) with a rock-salt crystal structure having many structural defects along the stacking direction of the intercalation compound.
