摘　　要：本文以陶瓷抛光废料为主要原料,辅以球土、长石、石英等,制备一种以闭口气孔为主的新型轻质建筑材料。在此基础上,采用XRD、体式显微镜、导热仪等研究了球土含量对试样的体积密度、抗压强度、物相组成、导热系数等性能的影响。实验结果表明:随着球土含量的增多,材料中莫来石相开始形成并逐渐增多,抗压强度也逐渐增强;另一方面,随着球土添加量的增加,试样中孔径明显变小,体积密度增大,相应的导热系数随体积密度的增大而直线增大。A new type of lightweight building material with mainly closed pores was prepared using porcelain polishing waste as main raw material and feldspar, ball clay and quartz etc. as minor raw materials. On this basis, effects of ball clay content on the properties of sample, such as the sintered bulk density, compressive strength, phase composition and thermal conductivity etc. were examined with X-ray diffraction （ XRD）, stereomicroscope and thermal conductivity meter etc. The experimental results showed that the mullite phase in the material begin to appear and gradually increase, and the compressive strength also enhances gradually with increasing the ball clay content. On the other hand, the pore size in the sample significantly decreases and the sintered bulk density increases with increasing the ball clay content, and the corresponding thermal conductivity coefficient linearly increases with increasing the sintered bulk density.
