Abstract

This study is performed to determine the effect of potassium chloride (KCl) solution as surfactant on the terminal settling velocity of Bi-2212 suspension. A suspension ratio 0.0033 g Bi-2212 powder per 10 mL ethanol plus 2 drops (∼ 0.05 mL) of KCl solution concentration varied up to 10.80 wt% and a standard suspension were used. Analysis of the terminal settling velocity curves and the corresponding zeta potential show that the optimal KCl solution concentration is at 5.21 wt%. It has the lowest terminal velocity of 0.384 cm/min, the highest zeta potential of 31.1 mV and the smallest particle size around 455 nm.
