摘　　要： 以电解锰废渣、废陶瓷磨细粉制备再生陶瓷墙地砖。以抗压强度、吸水率、气孔率、体积密度为主要参考指标,研究再生陶瓷墙地砖的最佳配合比及最佳烧成制度,探讨烧成制度对其性能的影响。结果表明:影响再生陶瓷墙地砖性能的主要因素由大到小依次为烧成温度、保温时间、成型压力。随着烧成温度的提高,样品抗压强度先增大而后降低,吸水率先降低后增大。再生陶瓷墙地砖的最佳配合比为10%电解锰废渣、90%废陶瓷磨细粉。最佳烧成温度为1150℃、保温时间为90 min、成型压力为98 MPa。制得样品的吸水率为0.75%,抗压强度为25.2MPa、体积密度为2.88 g/cm3,符合GB/4100-2006《陶瓷砖》中BIa类标准。 Recycled ceramic tiles were prepared from electrolytic manganese slag （EM） and waste ceramic grinding fine powder （GP）. The optimal mix proportion and firing system of the preparation of recycling ceramic tile were investigated with compressive strength, water absorption, porosity and bulk density as the main analysis indexes. The effect of firing system on properties of ceramic tile was also measured. Results show that factors affecting properties of ceramic tile in descending order were sintering temperature, holding time and molding pressure. The compressive strength of samples increased first and then decreased with sintering temperature increasing, while water absorption declined first and then increased. The optimal mix proportion of recycled ceramic tile was 10% EM and 90% GP. And the optimal firing system was sintering temperature 1150 ℃, holding time 90 min and molding pressure 98 MPa, respectively. Under the optimal mix proportion and firing system condition, the samples has compression strength 25.2 MPa, water absorption 0.75% , bulk density 2.88 g/cm^3, which meet the national standard GB/4100-2006.
