Abstract

A method for preparing titanium monoxide powder materials relates to a method for preparing high-purity titanium monoxide powder materials through adopting a thermal reduction method, particularly to a method for preparing high-purity titanium monoxide powder materials. The method is characterized in that dititanium trioxide and high-purity hydrogen are taken as basic materials to carry out the high-temperature thermal reduction reaction. In the invention, hydrogen and dititanium trioxide are reduced to titanium monoxide at a high temperature through changing base materials (namely, replacing titanium dioxide with dititanium trioxide), so that the high-purity titanium monoxide is obtained.

Description

technical field [0001] The invention discloses a method for preparing titanium monoxide powder material, which relates to the preparation of high-purity titanium monoxide powder material by thermal reduction method, especially the preparation method of high-purity titanium monoxide powder material. Background technique [0002] Titanium monoxide and gold belong to the same face-centered cubic crystal system, and its color is closest to the color of gold in nature, so titanium monoxide can be used in the decoration industry and related fields. In addition, titanium monoxide can be used as a catalyst for ethylene polymer reactions and is widely used in the semiconductor industry. [0003] At present, the preparation methods of titanium monoxide mainly include magnesium reduction titanium dioxide method under hydrogen atmosphere, hydrogen reduction titanium dioxide method under hydrogen atmosphere, carbon reduction titanium dioxide method, and titanium reduction titanium dioxid...
