Calcium titanate system of ERF
The electrorheological properties and current density,[link widoczny dla zalogowanych], the system performance of the concentration of ER is very sensitive, but the viscosity of silicone oil is not particularly selective. Study found that the particles contain polar hydroxyl groups, carbonyl and other properties of high yield strength play a key role, different from the traditional theory and the dielectric surface of the newly proposed mechanism of saturation polarization theory.
