摘要
以节约粘土资源及开发新型节能建筑材料为目的,利用长江沿岸低品位石英砂开发研制多孔陶瓷。研究了烧成工艺对石英砂基多孔陶瓷孔结构及性能的影响,为新型隔热保温材料的开发提供了工艺参考依据。研究结果表明,利用长江沿岸低品位石英砂成功地研制出多孔陶瓷,其密度随烧结温度的升高或保温时间的延长而增大,气孔率则随烧结温度的升高或保温时间的延长而降低。从能耗、成本与性能3方面考虑,石英砂基多孔陶瓷较合理的制备工艺参数为烧结温度1100℃、保温时间60min。
In order to save the clay resources and exploit the new building material to save energy, the quartz porous ceramics were researched with the low grade quartz sand along the Yangtze River. The effect of sintering technology on the porous structure and performances of quartz porous ceramics was researched, which lay technology foundation for increasing the performance of heat insulating materials. With an increase of sintering temperature, the microstructure of the samples changes while the density increases and the porosity decreases. The density of the porous quartz ceramics increases with extension of holding times, but the porosity decreases. The optimum sintering conditions for the quartz porous ceramic was 1100℃ and 60min, which determined by analyzing energy consumption, cost and properities of the quartz porous ceramics.
