Method for preparing air-permeable material
The invention relates to a method for preparing an air-permeable material, and aims to provide a method for preparing a high-strength air-permeable material; and the method disclosed by the invention comprises the steps of obtaining materials, ball-milling, granulating, making a bulk with a hole, filling loose powder, loose pre-sintering, carrying out acidic treatment, loose sintering and cooling, wherein the air-permeable material comprises the following raw materials in percentage by weight: 80-89% of Al2O3, 6-13% of ZrO2, 0.5-1% of MgO, 0.01-0.05% of SiO2, and 4-13% of carbon powder. The method disclosed by the invention is simple in process, strong in operability and high in production efficiency and is applied to preparing all kinds of air-permeable materials; and furthermore, the prepared air-permeable material has the advantages of being high in structural strength and good in air permeability.
