Abstract

The preparation of pure geikielite, MgTiO3, is carried out by precipitation with NaOH solution at pH ∼12 from solutions Ti4+/Mg2+ in molar ratio 1/1 M and calcination of the precipitate at 600°C in a dynamic atmosphere: heating rate 300°Ch−1.

At room temperature and a 1 KHz of frequency the dielectric constant (ɛ) and the electric resistivity (ρ) were measured. The values were ɛ = 1 5.0 and ρ = 1.1×1010 Ω cm−1.
