Embodiment 1
[0013] Embodiment 1: raw material formula mud 5-25 CaCO 3 30-50 MgCO 3 0-20 high-alumina sand 10-40, after ball milling, spray drying to powder, dry pressing and firing.
Embodiment 2
[0014] Embodiment 2: raw material formula mud 5-25 CaF 2 30-50 MgO0-10 High alumina sand 10-40, after ball milling, spray drying to powder, dry pressing and firing.
Embodiment 3
[0015] Embodiment 3: the powder material made in embodiment 1 or embodiment 2 and the existing polishing brick production powder are mixed in the ratio of 40:60 or 50:50 or 60:40 and then dry-pressed, dried and fired Can.
[0016] In above-mentioned embodiment, owing to have selected CaCO for use in the raw material 3 , CaF 2 , CaO and CO are produced during firing 2 , F 2 etc., where CO 2 , F 2 Gas escapes to generate pores, and CaO plays a role in cooling and promoting sintering, so as to obtain porous sintered functional ceramic bricks with communicating channels.
