Embodiment Construction

[0017] The present invention is further described in detail below.

[0018] A method for preparing superfine titanium suboxide powder, the steps are as follows:

[0019] A. According to TiO 2 +TiH 2 →xTi 4 o 7 +yTi 5 o 9 (x+y =1) reflect the equation for calculation, weigh titanium dioxide powder and titanium hydride powder on the electronic balance, so that the mass ratio of titanium dioxide powder and titanium hydride powder is 39:5, and the powder particle size is required to be 1- 10μm;

[0020] B. The above-mentioned titanium dioxide powder and titanium hydride powder were dropped into supersaturated KCl and NaCl aqueous solutions respectively, and stirred for 10 minutes with a stirrer to obtain KCl and NaCl aqueous suspensions containing titanium dioxide powder and titanium hydride powder respectively;

[0021] C. Filter the above mixed solution with a 3-5um filter paper, and then dry it in a constant temperature drying oven at 100°C in an air atmosphere to obtain...

Abstract

The invention relates to a preparation method of ultra-fine titanium suboxide powder. The preparation method comprises the following steps: A. weighing titanium dioxide powder and titanium hydride powder in proportion; B. respectively adding into supersaturated KCl and NaCl aqueous solutions, and stirring for dispersion; C. respectively filtering and drying the mixtures; D. carrying out high-temperature dehydrogenation treatment on the titanium hydride powder coated with KCl and NaCl, and then sufficiently and evenly mixing with the titanium dioxide powder coated with KCl and NaCl, as well as KCl and NaCl powder; E. heating the evenly mixed powder in vacuum, and then cooling in a furnace; F. washing with water to obtain the ultra-fine titanium suboxide powder. The preparation method provided by the invention solves the problem that ultra-fine titanium powder is different to prepare, meanwhile increases the purity and dispersibility of the titanium powder, and improves the production efficiency, and the controllability of powder particle size is good.
