According to the ceramic building block provided by the invention, ceramic is used as a main raw material, under the condition that traditional components such as cement, sand and lime are not added, only three ceramic raw materials with different particle sizes and proportions are compatible, and a conventional curing process is performed under the action of sodium silicate, so that relatively high use strength can be achieved, and addition of cement is omitted; and the manufacturing cost of the building block is effectively reduced.
