ZrO 2 contamination from the vial and balls was eliminated by dipping the ball-milled SiO powder in (NH 4)HSO 4 molten salt and heating for 5 min. The disproportionated SiO powder showed characteristics comparable to those of a powder prepared by a conventional heating process taking several hours.

The preparation of the crystalline ZrTiO 4 powder phase from the amorphous one, was possible if the samples were exposed to a subsequent heat treatment. The structural transformations occurring during heating the samples went in two different ways depending upon the previously used milling assembly.
