Abstract

PURPOSE:To obtain a molybdenum oxide whisker having the form of filament, rod, flake, etc., easily, by calcining an organic molybdenum compound in an oxygen-containing atmosphere at a temperature above the decomposition temperature of the compound. CONSTITUTION:An organic molybdenum compound such as molybdenum [VI] dioxyacetylacetonate, molybdenum [VI] acetylacetonate, etc. is used as a raw material, an is calcined in an oxygen-containing atmosphere, e.g. in air at a temperature above the decomposition temperature of the compound. A molybdenum oxide whisker having the form of filament, rod, flake, etc., can be prepared easily by this process. The molybdenum oxide whisker prepared by this process is expected to be useful as various industrial materials such as filler for plastics, etc.

In the present invention, these organic molybdenum compounds are placed in, for example, an alumina substrate, a magnetic crucible, a heat-resistant open container such as a quartz container, and fired in an oxygen-containing atmosphere. Here, the oxygen-containing atmosphere means oxygen or an atmosphere containing oxygen, and may be, for example, oxygen or air. The firing temperature is set to be higher than the temperature at which the organic molybdenum compound thermally decomposes.
