Electrophoretic Studies on Silicon Nitride Traces of Silicates in UPW Shift Zeta Potential Similar to SC-1

摘要

In this paper we report on a new method of controlling the zeta potential of Si3N4 particles by addition of silicate traces to neutral ultra pure water (UPW). The positive zeta potential of Si3N4 at neutral pH shifts to negative values similar in alkaline pH solutions (e.g. with ammonia).
