Abstract

The invention relates to a method for preparing a titanium sesquioxide material. The method is characterized in that a preparation process uses titanium dioxide and graphite as basic raw materials and carries out the preparation by a hot reduction reaction. The method for preparing the titanium sesquioxide material of the invention uses titanium dioxide and graphite as basic raw materials and carries out the preparation by a high temperature thermal reduction method. The titanium sesquioxide is prepared directly by a one-step carbothermic process, so as to save technological steps and reduce usage of a restorable harmful substance titanium tetrachloride. Therefore, the method reduces cost as well as mitigates environmental pollution.

Description

technical field [0001] The invention relates to a method for preparing dititanium oxide material. Background technique [0002] Titanium-doped sapphire (Ti:Al 2 o 3 ) is the basic raw material for the manufacture of solid-state tunable lasers. It can form very short pulses, and the noise is only one-tenth of that of tunable dye lasers. It has a wide range of applications in remote sensing measurement, lidar, and submarine communications. And titanium-doped sapphire (Ti:Al 2 o 3 ) The basic raw material required for the preparation is reducing titanium dioxide. At present, the method for preparing titanium dioxide is mainly to directly reduce titanium dioxide with hydrogen in the presence of titanium tetrachloride to prepare titanium dioxide. These methods are complicated in process and contain titanium tetrachloride, a volatile substance. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, to provid...
