摘要：
Dielectric fluids whose dielectric constants depend on temperature and moisture content have been prepared by dispersing barium titanate particles in kerosene. Ultrafine barium titanate of average particle size < 10 nm has been coprecipitated by hydrolysis of titanium alkoxide containing barium, and shows good dispersion into kerosene when coated with polyoxyethylene alkyl ether acetate as surfactant. When an electric field gradient is applied to the dielectric fluid with little moisture, an immersed dielectric glass sphere experiences a levitational force.
