添加透辉石的炻质外墙砖性能与显微结构初探

STUDY ON PROPERTIES AND MICROSTRUCTURE OF THE STONEWARE OUTSIDE WALL TILE USING THE DIOPSIDITE

在以红黄粘土为主要原料的一次低温快烧炻质外墙砖坯料中 ,引入 1 0 %wt透辉石 ,经生产实践证明 ,加入透辉石后可使产品抗弯曲强度提高 ,吸水率下降。借助于XRD、偏光显微镜 ,对烧后胎体显微结构进行分析 ,研究发现 ,添加透辉石后使胎体中莫来石含量上升 ,胎体主要矿物成分是石英并构成骨架 ,石英与莫来石、赤铁矿、钙长石。

This paper main describes that the adding dioposidite(10%wt)stoneware outside wall tile production raw materials.technological process.mineral composition.micro-structure and physical properties of the producks.The study shows that the adding of the diopsidite can help the formation of mullite.Moreover,the industrical production shows that the adding of diopsidite can improve quality of the products.
