                         This study reports on the processing of Al2O3-Nb2O5-Ta2O5 powder 
                         mixtures by ball milling varying their molar ratio: 50/45/5, 
                         50/5/45 50/50/0, and 95/5/0. The milling process was carried out 
                         in a Fritsch P-7 planetary ball mill using zirconium oxide balls 
                         (10 mm diameter) and vial (80 mL), 600 rpm, and a ball-to-powder 
                         weight ratio of 10:1. The characterization of milled 
                         Al2O3-Nb2O5-Ta2O5 powders was conducted by means of X-ray 
                         diffraction, BET analysis, He picnometry, and scanning electron 
                         microscopy techniques. Results indicated that metastable phases 
                         were formed during ball milling of Al2O3-Nb2O5-Ta2O5 powder 
                         mixtures, and no evidence of AlNbO4 neither AlTaO4 was found after 
                         milling for 300 min. Despite the low specific area for as-catalyst 
                         applications the pore amount was slightly increased during ball 
                         milling.",
