Embodiment 1
[0054] (1) Ingredients: Take 50Kg of yellow phosphorus waste residue and 30Kg of clay shale and grind to a particle size of 80μm, take 19Kg of charcoal powder and pulverize it to 180μm, take 0.8Kg of water glass and dissolve it in 8Kg of water, and then mix yellow phosphorus waste residue, clay shale, charcoal Mix the powder and water glass solution evenly;
[0055] (2) drying the uniformly mixed ingredients at 105°C for 30 minutes to obtain a green body;
[0056] (3) The dried embryo body is pressed and formed under a pressure of 15KN by a unidirectional compression molding method, and kept for 25 minutes under a pressure of 15KN;
[0057] (4) Sinter the pressed green body at 1140° C. for 60 minutes, keep it warm for 210 minutes, and then cool down to room temperature with the furnace to obtain the porous ceramic material.
