Abstract

PURPOSE: To prepare an innumerable number of Cr2O3 whiskers, easily, by calcining a mixture of Cr2O3 powder, C powder and optionally silicate compound powder at a high temperature above a specific temperature.
CONSTITUTION: A mixture of Cr2O3 powder and C powder such as graphite powder, or a mixture of the above mixture with a silicate compound is prepared beforehand. The silicate compound is, e.g. mullite (3Al2O3.2SiO2). The mixture is charged in a vessel made of e.g. alumina, and calcined at ≥1,350°C, preferably ≥about 1,500°C to obtain the objective Cr2O3 whisker. The vessel is so constructed as to be supplied with a small amount of external air. The Cr2O3 whisker obtained by the process is 3W10μm in thickness and 500W1,000μm in length.
