Stability of suspensions of ferroelectric BaTiO/sub 3/ particles in hydrocarbon carrier liquids
The stability of suspensions of ferroelectric (BaTiO/sub 3/) nm-particles, using heptane as carrier liquid and oleic acid as stabilizer, is investigated by means of electrooptic Kerr rotation and optical transmittance. On suspension up to 0.006 solid volume fraction, with permanent dipole moments existing at 5 nm>
