. The niobium particle size increased significantly as the reduction temperature increased from 993 to 1093 K. The particle … size was fairly uniform at a given reaction temperature, varying from 0.2 μ m to 50 nm depending on the reaction … temperature. The yield of niobium powder increased from 58 to 83% with an increase in reaction temperature. The average particle …
