Abstract
The invention provides a method for manufacturing a honeycomb ceramic tile. The honeycomb ceramic tile is formed by inlaying a honeycomb convex blank made of ceramic material in a honeycomb concave blank and sintering the two blanks. The method for manufacturing the honeycomb ceramic tile comprises the steps that the honeycomb convex blank and the honeycomb concave blank are manufactured by use of molds and press machines; the honeycomb convex blank and the honeycomb concave blank are dried, inlaid, combined and then sintered after the surface of a tile is glazed. The method has the advantages that as a honeycomb-shaped cavity is arranged in the honeycomb ceramic tile, 15 to 30 percent of the ceramic materials can be reduced, which saves a large amount of ceramic raw materials, reduces energy loss for firing the ceramic tile at the same time, and is favorable for saving energy and reducing emission.
