氧化钛(III) 制备方法及用途

合成制备方法

按反应计量将金属钛和二氧化钛混合,加压成型后放入氧化铝坩埚,真空条件下于1600℃加热1.5~2h即可得到三氧化二钛。将盛有准确称量的二氧化钛的瓷燃烧舟放在石英制或瓷制的燃烧管中,并用氢气排出空气,将它在1100~1200℃下于干燥氢气流中煅烧1.5~2h,制得的产物在氢气流中冷却。

氧化钛(III) 物化性质

外观与性状:
紫罗兰色六角形的晶体
熔点:
2130ºC
存储条件/存储方法:

保持贮藏器密封、储存在阴凉、干燥的地方,确保工作间有良好的通风或排气装置

 

稳定性相关:

如果遵照规格使用和储存则不会分解,未有已知危险反应,避免氧化物。三氧化二钛有两种变体:α-Ti2O3和β-Ti2O3。在较低温度下以α-Ti2O3存在,在较高温度下以β-Ti2O3 存在,两种变体的转化温度为200℃。在空气中稳定,具有P型半导体性质。能溶于热的40%氢氟酸,能慢慢地与热硫酸作用,不溶于盐酸、硝酸及氢氧化钠。
