Witryna10 wrz 2013 · It was recently discovered that a transparent n-type (Ba,La)SnO 3 system has electrical mobility as high as 320 cm 2 V − 1 s − 1 at room temperature and superior thermal stability up to ∼500 °C. To understand comparatively the carrier-scattering mechanism in the doped BaSnO 3, we investigate the physical properties of the … Witryna1 kwi 2003 · A novel way of purification has been found recently. A silver-extracted residue that contains 21.35% Sb was used to adsorb bismuth, antimony, and arsenic from copper electrolyte (Wang et al., 1998). The residue is obtained from copper anode slime that is treated by volatilizing Se in a rotary kiln, leaching copper in acid solution, …
