Crystallographic Study of Potassium Hexa-titanate

Abstract

The singl crystals of potassium hexa-titanate were synthesized by melt reacting TiO₂ and K₂CO₃, from which lattice parameters, indexes of X-ray powder diffraction data and infrared spectra were obtained.
The crystal system of potassium hexa-titanate was monoclinic. The space group was C*/* (C2, Cm, C2/m) and the cell dimensions were a=15.5878±0.0018Å, b=3.7979±0.0003Å, c=9.1131±0.0013Å, β=99.75±0.015°. This unit cell contained 2 (K₂Ti₆O₁₃)
