Preparation of chromium dioxide for magnetic recording applications

摘要

Magnetic-tape-grade chromium dioxide has been prepared by a single step synthesis employing hydrothermal decomposition of commercially available (303.Acicular growth is induced by antimony trioxide addition. Enhancement in magnetic properties has been obtained by using x201C;mineralizersx201D;. The material has been characterized, and its magnetic and other properties are found to he suitable for use on audio, video, and computer tapes.
