Abstract:
A lapping slurry and method of making the lapping slurry are provided. The lapping slurry comprises abrasive grains dispersed in a carrier. The carrier comprises water, ethylene glycol and between about 0.5 wt % to about 60 wt % surfactant. Abrasive particles are positively charged when dispersed in ethylene glycol having a pH in a range of from 5 to 9, as evidenced by zeta potentials.
