Method for preparing lambda-Ti3O5 functional material
The invention discloses a method for preparing a lambda-Ti3O5 functional material, which comprises the following steps: (1) taking TiO2 powder and oxide of metal M as raw materials, metering the ratio of the raw materials according to the molar ratio of metal element atom M/Ti of x: (3-x), and x is more than or equal to 0.09 and less than or equal to 0.40; (2) fully grinding the raw materials metered in the step (1) to obtain mixed powder, and carrying out compression molding on the mixed powder in a mold to obtain a molded block; (3) in the atmosphere of inert gas, laser heating reaction is carried out on the formed block obtained in the step (2) at the high laser power density, the temperature of the laser heating reaction ranges from 1800 DEG C to 2300 DEG C, and a sintered block A is obtained; (4) slowly reducing the laser power density and enabling the laser to continuously act on the sintered block A obtained in the step (3) to obtain a sintered block B; and (5) after the sintered block B is naturally cooled, the lambda-Ti3O5 functional material is prepared.
本发明公开了一种制备λ‑Ti3O5功能材料的方法，包括以下步骤：(1)原料为TiO2粉体和金属M的氧化物，按照金属元素原子M/Ti摩尔比为x:(3‑x)来计量各原料配比，其中0.09≤x≤0.40；(2)将步骤(1)中计量好的各原料进行充分研磨得到混合粉料，将混合粉料在模具中压制成型，得到成型块体；(3)在惰性气体的氛围下，以高激光功率密度对步骤(2)所得成型块体进行激光加热反应，所述激光加热反应的温度为1800～2300℃，得到烧结块体A；(4)然后再缓慢降低激光功率密度并使激光持续作用于步骤(3)所得烧结块体A，得到烧结块体B；(5)待烧结块体B自然冷却后即制得所述λ‑Ti3O5功能材料。
