Problems solved by technology

Among them, the reaction conditions of the magnesium reduction titanium dioxide method and the carbon reduction titanium dioxide method are relatively harsh, the oxygen content is not easy to control, and the product content is unstable; the reaction conditions of the hydrogen reduction titanium dioxide method and the reduction of titanium trioxide method are harsh, and they need to be placed in a high-temperature and high-pressure container. The reaction can only occur; although the titanium reduction titanium dioxide method can avoid the above-mentioned problems, it is limited by the reaction conditions and stoichiometric ratio, and it is easy to cause the surplus of titanium or titanium dioxide. It takes a lot of experiments to adjust the parameters involved in the reaction to find the best combination Ratio and Reaction Parameters

Abstract

The invention provides a preparation method of high-purity titanium monoxide and belongs to the technical field of preparation of titanium monoxide. The preparation method comprises the steps that: high-purity titanium powder and high-purity titanium dioxide are prepared into powder with the granularity of 600-1000 meshes according to the mass ratio of 53: 47, and the powder is mixed; the preparedpowder is put into a specially-made aluminum oxide crucible, and the crucible is put into a calcining furnace; and under the condition of vacuum degree, calcining is performed for 4-8 hours at the high temperature of 1250-1400 DEG C to obtain the high-purity titanium monoxide. According to the method for preparing the high-purity titanium monoxide, the low-valence metal oxide is prepared from themetal and the metal high-valence oxide, and therefore, pollution of impurity metal is avoided.

Description

technical field [0001] The invention relates to a preparation method of titanium oxide. In particular, it relates to a preparation method of high-purity titanium monoxide. Background technique [0002] Titanium monoxide and gold belong to the same face-centered cubic crystal system, and its lattice parameter is closer to that of gold than that of titanium nitride. In nature, the color of titanium monoxide is closest to that of gold. Proper selection of the binder phase and improvement of its toughness are expected to produce titanium monoxide-based imitation gold materials, which can be used in the decoration industry and related fields. In addition, titanium monoxide can be used as a catalyst for ethylene polymerization and is used in the semiconductor industry. [0003] At present, there are five methods for preparing high-purity titanium monoxide: magnesium voluntary method, hydrogen voluntary method, carbon reduction method, hydrogen reduction of titanium trioxide, an...
