Capillary electrochromatography uses electroendosmotic flow (EOF) to perform highly efficient separations in small-diameter fused-silica capillaries, packed with HPLC-type stationary phases. It can be considered as a combination of capillary electrophoresis (CE) and HPLC. The separation of solutes is based on electrophoretic mobility (for charged species) and interaction with the stationary pha.se, allowing the separation of both neutral and charged compounds. 

Ternary phase equilibria at 1300°C (fig. 19) are characterized by the formation of continuous solid solutions Ce3 j Th Si2 with the U3Si2-type, Ce,. . Th Si with... 

NdRej crystallizes with the MgZn2-type the phase relations in the binary systems Nd-Si and Re-Si are discussed in context with the ternary systems Ce-Nd-Si and Y-Re-Si. The mutual solid solubilities of Nd and Re silicides as well as of NdRej at 800 °C were found to be small and within 1-2 a/o of the third constituent. 

In these segregations between the FM and antiferromagnetic CE or Type-A phases, the competitive phases appear to have similar Mn(IV)/Mn ratios the phase segregations do not require a separation into hole-rich and hole-poor...
