Witrynaimpurities are compared, there is limited indication of interaction between impurities. For example, copper improves the efficiency of Ti- and V-doped cells, although the effect is small. Apparently, Cu diffuses to and combines with the second transition metal to reduce its electrical activity. Precipitated impurities have little or no effect ...

Witryna1 sty 2006 · We investigated the thermal properties and the glass formation region in the Bi2O3-B2O 3-ZnO ternary system. The results showed that the ratio of T g/Tl of the bismate glasses is around 0.55 ... WitrynaAn impure substance is a combination or mixture of two or more different substances that are not chemically bonded together. Purity is how pure a substance is or the degree to which a substance is free from contamination. An impurity is a substance that is mixed with, and contaminates, a desired substance.
WitrynaA special cryogenic sampling cell (<-80°C) for laser ablation has been constructed. The focused (5-10μm width) laser shoots at the frozen sample, scanning its surface. The vapor is fed to the mass spectrometer. In this way, the impurity concentration as a function of position in the crystal can be measured.
