盐酸改性煅烧高岭土的制备及表征
|
摘要
为了研究高岭土煅烧以及煅烧再改性后的结构变化,将鄂尔多斯高岭土分别在200、400、600、800℃下煅烧,得到煅烧高岭土试样,再将煅烧高岭土分别用质量分数5%和25%的盐酸进行改性,得到酸改性煅烧高岭土.采用XRD、FT-IR、SEM等手段进行表征分析.结果表明,在600℃的煅烧温度下高岭土的结构没有发生变化;当温度高于600℃煅烧时高岭土的结构发生了明显变化,已转变成偏高岭土;盐酸改性煅烧过的高岭土不能改变煅烧高岭土的结构.
In order to study the structural changes of kaolin after calcination and calcination and re-modification,ERDOS kaolin was calcined at 200,400,600 ℃ and 800 ℃,respectively,to obtain calcined kaolin samples,andthen calcined kaolin was modified with 5% and 25% hydrochloric acid,respectively,to obtain acid-modifiedcalcined kaolin. The samples were characterized by XRD,FT-IR and SEM. The results show that the structure ofkaolin does not change at the calcination temperature of 600 ℃. When the temperature was higher than 600 ℃,thestructure of kaolin changed obviously to metakaolin. Hydrochloric acid modified calcined kaolin can not change thestructure of calcined kaolin.
