    摘要: In a process and apparatus for producing ceramic tiles, such as wall tiles and floor tiles, including thin tiles of a size up to a square meter, metal electrode plates having thereon three-dimensional design and insulating paint or tape defining the boundaries of one or more tiles to be produced, are transported by a conveyor system through a bath of finely divided ceramic material suspended in an aqueous electrolyte while applying an electric potential between the plates and a counter electrode in the bath to produce electrodeposition of ceramic material from the bath onto conductive portions of the plates bounded by the insulating material. The voltage and time of travel in the bath are selected to produce a deposit of ceramic material with a thickness of from 1 to 20 mm. After leaving the bath, the plates, with the deposits thereon are transported through a water spray rinsing station and a drying atmosphere to a transfer station at which the deposits, constituting green tiles, are transfered to refractory supports by which they are carried through a tunnel furnace for further drying and firing. From the transfer station, the plates are further transported through a reconditioning station and back to the bath. Thin flexible water-wettable membranes applied to the plates before deposit of ceramic material thereon facilitate removal of the green tiles from the plates at the transfer station without damage.

    摘要: A method of electrophoretic deposition of a ceramic green body. A ceramic powder is optionally washed with a polar solvent such as deionized water, dried, and suspended in a polar organic solvent in a proportion of at least 20% by weight. A positive surface charge is imposed on the suspended particles by conventional means such as ball milling or ultrasonic treatment. A green body is deposited on a cathode by passing a direct electric current of constant current density through the suspension. The density of the green body generally is at least 70% of theoretical. The density of the fired body generally is at least 98% of theoretical. A layered green body may be deposited by using several suspensions of differing global ceramic composition and depositing each microlayer in a different suspension.

    摘要: A controlled layer of base mass is uniformly applied to a dental crown or bridge 10 of noble metal alloy by electrophoretic separation in a glass container 14 after an intermediate layer of galvanized zinc or tin is first applied in a container 13. The intermediate layer may be omitted if the crown or bridge is made of a non-noble metal alloy. The containers are provided with semi-cylindrical cathodes 15, 16 coupled to an electrical supply by jack plugs 19, 20. The crown or bridge serves as the anode and is held by tongs 21, 22 connected by cables 23, 24 to the power supply, and both the magnitudes and durations of the bath currents are adjustable. The liquid suspension of the base mass in the electrophoretic bath is maintained by a magnetic stirrer 27.
