ELECTRO-CERAMICS The term Electro-ceramic is used to describe ceramic materials that have been specially formulated for specific electrical, magnetic, or optical properties. There are a wide variety of ceramic materials that have electromechanical, electrochemical, electromagnetic, electro-optic or other electric responses. Features of Electro-ceramics * Based on well-defined and high purity raw materials. * Making mould able paste by mixing binder, plasticizer, solvent and dispersant. * Fired at high temperature. The performance of electro-ceramic materials and devices depends on the following things. * complex interplay between processing, * chemistry, * structure at many levels and * Device physics. Electro-ceramics are categorized under new ceramics. These kind of ceramics highly applicable in engineering applications. Advantages of Electro-ceramics * Much higher torque compared to the conventional drives of the same volume. * Generation of low speeds, adjustable down to zero, without the need for gearing. * No loss of torque at high or low speed. * Large holding torque at rest without additional energy supply. * Extremely high dynamics and excellent controllability. * Completely lack of inertia and practically instantaneous moving in any direction. * Quiet running in the audibly range. * Compact design and high degree of miniaturization. * Simple mechanical components. * No magnetic field and hence no electromagnetic disturbance.
