Title: Photometric determination of Nb in steels with PAR
Abstract: Use of 4-(2-pyridylazo)-resorcinol (PAR) in the photometric determination of 0.2 to 3% of Nb in Zr steels is described. A detailed description is presented of the Nb determination procedure in a l g sample by means of a calibration curve. The amount of W up to 5%, Ti up to 5%, Ta up to 1.6%, and Zr up to 1% did not affect the determination. (INIS)
