Nonferrous Met. Soc. China 25(2015) 444-450 High temperature mechanical behavior of alumina dispersion strengthened copper alloy with high content of alumina Zi-qi XIANG1, Zhou LI1,2, Qian......
and in combination on the dispersion stability of nano-TiO2 aqueous suspension were investigated by ultraviolet-visible absorption spectroscopy. The adsorption mechanism of these dispersants was detected by zeta... of dispersants and the salt concentration were studied. In order to investigate the mechanism of co-adsorption of these two dispersants, the results from electrokinetic analysis and dispersion stability were......
