Niobium - an overview | ScienceDirect Topics

Niobium and tantalum containing Y zeolites prepared via the one-pot synthesis showed the FAU structure, as evidenced by XRD diffraction patterns (Fig. 1 – the numbers in the symbols indicate the assumed Si/M ratio). The zeolite structure is confirmed for the two zeolites of both Si/M ratios (64 and 32); hence the synthesis of faujasite samples was successful.
