The invention discloses a process for producing foamed ceramic through layered material preparation and allocation and belongs to the field of materials. According to the process, multiple foamed ceramic granule materials of different oxidant contents and granularities are adopted to produce a foamed ceramic material through layered material preparation and allocation. Due to the adoption of oxidants, a foaming agent in a ceramic raw material can be promoted to be oxidized to generate gases; due to the adoption of a setup mode of small lower-layer granule particle sizes, high oxidant contents,large upper-layer granule particle sizes and low oxidant contents, channels are provided for low-temperature gas exhaust, and the low-temperature gas exhaust time can be shortened; moreover, the setup mode is beneficial to heat conduction, uneven foams caused by temperature gradients can be made up, the heating velocity in a foaming combustion period can be increased, the foaming temperature keeping time is shortened, and furthermore the production period of the whole foamed ceramic material can be shortened; the foamed ceramic material is prepared from the foamed ceramic produced through layered material preparation and allocation, and is high in quality, small in defect, short in production period and applicable to on-scale production.
