Abstract: A method for making large-size hollow ceramic plate (1, 2, 4) adopts raw materials of ordinary ceramics, mixing with industrial wastes or crude minerals abundant in period IV transition metal elements, squeezing a molded body by vacuum squeezing machine then producing at low cost a large-size hollow ceramic plate (1, 2, 4) with black or fuscous surface or whole body, with an area more than 0.5m2 of a single plate. A large-size hollow ceramic plate array (23) is composed of porous ceramic plates (1), through-hole ceramic plates (2) and accessories by gluing or thread-connecting or is composed of seal ceramic plates (4) by series connecting, which can be used in a solar water heater, a solar roof and wall, a generator with large-scale solar wind duct, a large-area solar collector, a far infrared radiation plate and a radiator for construction.

Abstract: The present invention discloses a novel black ceramic and a method of producing the same. This method employs a variety of industrial wastes and natural ore as starting materials to greatly decrease the cost of producing black ceramic materials. The black ceramic material of the present invention has many uses, such as, infrared radiating elements, fillers in plastics and rubbers, pigments in decorative architectural coatings and surfaces.
