Research on Green Preparation Process of Porous Ceramics
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.
