Abstract

The electrostatic stability of Bi2Sr2CaCu2O8 (Bi-2212) in ethanol medium with common salt (NaCl) as a supporting electrolyte was studied. Finely ground Bi-2212 was mixed with ethanol, and a minute amount of aqueous solution of NaCl at concentrations varied from 0 to 11 wt% was added to the suspension. The stability of the Bi-2212 suspensions was evaluated in terms of zeta potential, particle size distribution, and settling velocity. It was found that the optimal NaCl concentration is 7.15 wt%. This resulted in the lowest zeta potential, particle size, and settling velocity, and hence exhibited the stability of Bi-2212 suspension. The results showed that NaCl is suitable as a supporting electrolyte for the Bi-2212 suspension.
