几种钛酸钾纤维的合成及其相关性研究

SYNTHESIS OF SOME POTASSIUM TITANATE FIBERS AND Their RELATION SHIP

本文以Ｋ＿２ＣＯ＿３和ＴｉＯ＿２为主要原料，采用混练－干燥－煅烧三步法合成出了Ｋ＿２Ｔｉ＿２Ｏ＿５、Ｋ＿２Ｔｉ＿４Ｏ＿９、Ｋ＿２Ｔｉ＿６Ｏ＿１３三种形式的钛酸钾纤维物质。测定了它们的ＸＲＤ、ＤＴＡ－ＴＧ、ＳＥＭ、ＩＣＰ、激光拉曼等有关特征数据和谱图，并对它们之间的相互关系进行了研究。

K_2Ti_2O_5K_2Ti_4O_9 and K_2Ti_6O_13 fibers were synthesised by the three stages method Kneading-Dry-ing-Calcination and the relation ships between any couple of the stages wad discussed.Some XRD.IR,DTA-TG and ICP data were given.
