 — Packaging trends and transit performance. Cost and sustainability are also affecting the packaging used to protect products in transit and on shelf. A growing amount of primary packaging has been light-weighted to use less material, so it is less expensive to transport and more environmentally friendly. But there is a balancing act.

 — In NaHCO3, Na2CO3, and HCl solutions columbite–tantalite solubility is low. Even in 1 m chloride solutions the content is within the limits of 10−5 m for Nb and 10−6 to 10−8 m for Ta. We conclude that hydrothermal transport of Ta and Nb is possible only in concentrated fluoride solutions.

For columbite, tantalite, tin slag and other Ta/Nb raw materials, the extraction of the valuable niobium and tantalum content and removal of the Th/U to waste, requires specialised digestion in e.g. hot HF/H 2 SO 4 …

Abstract. Hall-effect and electrical-conductivity measurements have been made on reduced single crystals of the perovskite potassium tantalate (KTaO 3) over the temperature range 1.6-295°K.Lattice scattering predominates above 100°K where the Hall mobility satisfies the empirical expression μ H =8×10 8 T-3 cm 2 /V-sec. The room-temperature value is 30 …
