摘　　要：对湖南界牌高岭石提纯样品进行X光检测，粗矿样中主要含高岭石，少量石英、长石和白云母；精矿样品中有高岭石和石英。采用背压法制样，消除择优取向带来的误差．用直接对比法对精矿样品进行含量测定，其测试效果令人满意，说明X光定量分析对于较强择优取向的粘土矿物同样可行。It is found that raw ore sample mainly containskaolinite and a little quartz, feIdsPar and muscovite, concentratesample contains kaolinite sample of Jiepai, Hunan Province. Mak-ing and puartz by x - ray test to purified kaolinite sample by backpressure metthe to eliminate erro resulted from preferential ori-entatbo and determining contents of concentrate sample by directcontrast metbo, the test reaches satisfactoty results. It is shownthat X - ray quantitative analysis aLso can be used to clay mineralshaving high preferential orientation caPacity.
