摘　　要：本文合成了结晶二钛酸钾纤维．根据化学定量分析、Ｘ—ｒａｙ衍射分析、ＤＴＡ差示热分析等，得到了熔融法六钛酸钾纤维的合成机理．Fiber crystals of K2Ti6O(13) were grown from the reaCtion between TiO2 and K2CO3 at 1100℃ by melt method. After leaching in boiling water to expel excess of potassiunions and calcining treatment,fibrous crystals of potassium hexatitanate were prepared. A synthptic mechanism of potassium hexatitanate by melt method was proposed through chemical quantitative analysiS. X-ray powder diffraction analysis the differential thermal analysis were carried out.
