Corundum-Ti2O3 two-phase material is a by-product obtained via adjusting the smelting process of low-ferrotitanium alloy. Al2O3 and Ti2O3 exist independently in raw material, which can be used as a refractory raw material. According to the results by thermogravimetry-differential scanning calorimetry and thermodynamic analysis, the oxidation reaction of Ti2O3 in the raw material starts at 700 ℃, and the reaction between Al2O3 and TiO2 starts at 1 263 ℃. The results by X-ray diffraction and scanning electron microscopy indicate that Ti2O3 completes the oxidation reaction at 800 ℃, which is affected by the decomposition reaction of Al2TiO5 at 1 300 ℃, only part of TiO2 and Al2O3 reacts at the corundum junction to form flake Al2TiO5. As the sintering temperature is increased to 1 400 ℃ and 1 500 ℃, the reaction of Al2O3 and TiO2 to form Al2TiO5 is gradually completed, and a typical columnar aluminum titanate is formed on the basis of flakes.

刚玉-Ti2O3共存物相是通过调整低钛铁的冶炼工艺得到的一种冶金副产品,其中Al2O3和Ti2O3两相独立存在,可以作为耐火材料原料使用。通过热重-差热结合热力学分析得知原料中的Ti2O3在700℃左右开始氧化反应,Al2O3和TiO2在1263 ℃左右开始反应,将原料在不同温度空气气氛下保温3 h烧成,由XRD结合SEM结果可知在800 ℃左右Ti2O3完成氧化反应,在1300 ℃受钛酸铝分解反应的影响,只有部分TiO2和Al2O3在刚玉交界处反应生成片状Al2TiO5。随着烧成温度升高至1400℃和1500℃,Al2O3和TiO2生成Al2TiO5的反应逐渐完成,在片状的基础上生成了典型的柱状的钛酸铝。

刚玉-Ti2O3共存物相是通过调整低钛铁的冶炼工艺得到的一种冶金副产品,其中Al2O3和Ti2O3两相独立存在,可以作为耐火材料原料使用。通过热重-差热结合热力学分析得知原料中的Ti2O3在700℃左右开始氧化反应,Al2O3和TiO2在1263 ℃左右开始反应,将原料在不同温度空气气氛下保温3 h烧成,由XRD结合SEM结果可知在800 ℃左右Ti2O3完成氧化反应,在1300 ℃受钛酸铝分解反应的影响,只有部分TiO2和Al2O3在刚玉交界处反应生成片状Al2TiO5。随着烧成温度升高至1400℃和1500℃,Al2O3和TiO2生成Al2TiO5的反应逐渐完成,在片状的基础上生成了典型的柱状的钛酸铝。

Corundum-Ti2O3 two-phase material is a by-product obtained via adjusting the smelting process of low-ferrotitanium alloy. Al2O3 and Ti2O3 exist independently in raw material, which can be used as a refractory raw material. According to the results by thermogravimetry-differential scanning calorimetry and thermodynamic analysis, the oxidation reaction of Ti2O3 in the raw material starts at 700 ℃, and the reaction between Al2O3 and TiO2 starts at 1 263 ℃. The results by X-ray diffraction and scanning electron microscopy indicate that Ti2O3 completes the oxidation reaction at 800 ℃, which is affected by the decomposition reaction of Al2TiO5 at 1 300 ℃, only part of TiO2 and Al2O3 reacts at the corundum junction to form flake Al2TiO5. As the sintering temperature is increased to 1 400 ℃ and 1 500 ℃, the reaction of Al2O3 and TiO2 to form Al2TiO5 is gradually completed, and a typical columnar aluminum titanate is formed on the basis of flakes.
