Embodiment 1
[0012] A method for preparing a dispersed air-permeable material. First mix 70-80wt% of carbonate minerals, 1-20wt% of fused magnesia, 0.5-5wt% of additives and 0.5-5wt% of silica powder as raw materials, and then add 4-6wt% of the above raw materials water, stirred evenly, and casted; then baked at 110°C for 8-14 hours, and fired at 1680-1700°C for 2-5 hours to obtain a diffused breathable material.
[0013] In this embodiment: the carbonate mineral is dolomite; the additive is iron oxide.
Embodiment 2
[0015] A method for preparing a dispersed air-permeable material. Except that the additive is zirconia, all the other are the same as in Example 1.
Embodiment 3
[0017] A method for preparing a dispersed air-permeable material. Except that the additive is a mixture of zirconia and lanthanum oxide, all the others are the same as in Example 1.
