The preparation method comprises the following steps: uniformly mixing the fly ash, the lithium slag, talc, albite, potassium feldspar and a foaming agent, and carrying out wet milling by using a ball mill to prepare slurry; performing spray granulation to obtain powder particles, and performing calcination treatment; and cooling to obtain the foamed ceramic material. The preparation method has the beneficial effects that the lithium slag and the fly ash are compounded according to a certain proportion for use, and a molten mass formed by the lithium slag at a relatively low temperature can exert migration and permeation effects to spontaneously arrange the longitudinal height of the raw materials, so that the surface tension of the molten mass at a final firing temperature has certain difference in different areas; due to the existence of the difference, the resistance change of pores in the foamed ceramic in the aspects of formation, growth and distribution is eliminated, and uniform ...
