· A series of manganese-niobium mixed oxide (Mn–Nb) catalysts were prepared by homogeneous precipitation method and tested for low temperature selective catalytic reduction of NO x with NH 3 (NH 3-SCR).These catalysts were characterized by N 2 adsorption, X-ray diffraction, H 2-TPR, X-ray photoelectron spectroscopy, NO x-TPD and NH 3-TPD.
The crushed ore is mixed with 5 to l0% of sulfuric acid and added water to about 5 to 30% of the weight of the ore. This pugged material is cured for 2 to 3 hours at 100 to 110 deg C and then cooled. The cooled mass is nitrateconditioned by mixing with a solution equivalent to 35 pounds of ammonium nitrate and 300 pounds of water per ton of ore.

· The salt is based on methyltrioctylammonium chloride diluted in toluene. Niobium is then selectively stripped out using oxalic acid and nitrate ions, while Ta is stripped by nitric acid. There are two existing methods for the separation of Ta and Nb by solvent extraction, namely collective and selective extraction.
Abstract Single crystals of niobium carbide nitride were obtained by zone melting growth in ambient nitrogen gas pressures of up to 9.0 MPa. Single crystals of δ-NbN or γ-NbN could not be obtained by this method, but single crystals of γ-NbN were obtained by
