solutions, pure calcium vanadate was synthesized using CaCl2 and NaVO3 according to stoichiometric ratio at room temperature in solution of pH 7 for 4 h. Following filtration and washing with deionized..., 1976, 21(6): 401–405. DOI: 10.1016/0013-4686(76)85115-8. [24] BRAIN, l. Thermochemical data of pure substances [M]. Beijing: Science Press, 2003.

) matrix (a=0.4049 nm). Therefore, the primary Al3Sc particles can act as nuclei for Al solidification [33]. However, it is known that the solid solubility of Sc in pure Al at 640 °C is about 0.31% (0.186... as function of T8 aging time at 155 °C The solid solubility of Sc in pure Al will be decreased as temperature is lowered. It was reported that it was decreased from 0.31% (0.186% in mole fraction) at 640 °C......
of 94.01%, and the gangue mineral is quartz. 2.2 Reagents Sodium oleate (NaOL) of chemically pure was used as the collector, a iso-decanol polyoxyethylene ether C10H21O(C2H4O)5H (JFC-5 for short..., respectively. The C1s peaks at 284.76, 286.11 and 288.82 eV occur in the spectrum of JFC-5, corresponding to C-C, C-O-C and O=C-O, respectively. For pure JFC-5, carbon atom exists in the two forms of C-C and C......
system is schematically shown in Figure 1. A rectangular water tank made of plexiglass was used to contain pure water. The tank has identical horizontal cross sections with dimensions of 150 mm×150 mm... bubbles is larger than that of spherical bubbles and therefore the following expressions are recommended for CD in pure liquid: (9) where Eo is the Etvs number and is defined as: ......
