Because the foaming agent needs a high-temperature liquid phase, the cost of the foamed ceramic is higher due to the influence of factors such as high firing temperature, high air consumption and the like in the process of producing the foamed ceramic in batches. The thickness of the existing foamed ceramic plate cannot be larger than 20cm, when the thickness of the existing foamed ceramic plate exceeds 20cm, the difference between the central temperature and the external temperature of the material is too large, the foaming inside and outside is uneven, and in the cooling process, because the temperature difference between the inside and the outside is too large, the distribution of thermal stress is uneven, so that the foamed ceramic plate is broken, the yield is too low, and the leftover materials are too much.
In order to solve the problems, the invention provides a foaming ceramic plate produced without a foaming agent and a method thereof.

The dimension of the foamed ceramic plate is 2.4-3.0 meters long, 0.6-0.9 meters wide and 0.2-0.4 meters thick, and the foam holes are 3-4 millimeters.
A method for producing a foamed ceramic plate without using a foaming agent, comprising the steps of:
and A, granulation: putting 60-90 parts of recovered dust powder with the silicon dioxide content of more than 50%, 10-20 parts of bentonite, 10-20 parts of glass powder, 25-35 parts of EPS particles and 2-3 parts of cellulose into balling equipment, adding water mist, mixing and stirring to prepare a 3-4mm sphere;
b, cloth material: b, putting the ball body obtained in the step A into a heat-resistant steel die;
c, sintering: sending the heat-resistant steel die subjected to material distribution into a heat treatment kiln for low-temperature, medium-temperature and high-temperature three-section sintering, and cooling to obtain a foamed ceramic plate;
d, processing: and processing the foamed ceramic plate into a foamed ceramic plate with a required specification according to the requirement.
Further, the balling equipment in the step A comprises a planetary mixing stirrer and a disc type balling machine.
