摘要：

The reaction between hydrazine and NbOPO4.nH2O (n<3) gives an amorphous solid with a high thermal and hydrolitic stability. The presence of hydrazine in the solid has been detected by several bands in the IR spectrum between 1500-1550 cm-1 and 3300-3400 cm-1. The solid maintains its amorphous nature after the elimination of hydrazine at 600-degrees-C, and below the crystallization temperature (800-degrees-C) we have an amorphous niobium phosphate free of hydrazine possibly with catalytic properties.
