Starting from the chemical composition,the ceramic raw material ratios and corresponding chemical compositions were calculated using ternary phase diagram theory.Porous ceramics were prepared by mixing,forming,curing,and calcining phosphorus slag as a calcium source,aluminum ash as an aluminum raw material,coal ash as a silicon raw material,and phosphogypsum as a foaming agent.When the phosphorus slag content is 76％,sintering at 1080 ℃ for 120 minutes results in porous ceramic granules with a bulk density of 353.9 kg/m3,compressive strength of 1.06 MPa,water absorption rate of 18.74％,and porosity of 71.8％.The study considered resource conservation,energy savings,and performance throughout the entire lifecycle.
