摘要：
The preparation of pure geikielite, MgTiO3, is carried out by precipitation with NaOH solution at pH approximately 12 from solutions Ti4+/Mg2+ in molar ratio 1/1 M and calcination of the precipitate at 600-degrees-C in a dynamic atmosphere: heating rate 300-degrees-C h-1. At room temperature and a 1 KHz of frequency the dielectric constant (epsilon) and the electric resistivity (rho) were measured. The values were epsilon = 15.0 and rho = 1.1 x 10(10) OMEGA cm-1.
