摘要
研究了化学气相合成制备ＴｉＯ２粉末反应器管壁结疤问题，提出了冷壁凝结抑制产物粉末产生硬疤的方法和作用机制。采用ＴＥＭ、ＳＥＭ、光学显微镜和ＸＲＤ分析了不同条件下ＴｉＯ２产物粉末、热壁硬疤和冷壁凝结软疤的形态和结构。
Formation of wall scale in the reactor during the process of chemical synthesis TiO2 in vapor phase has been investigated. The method and mechanism about restraining producing powder anomaly glowing up to form hard wall scale by condensation with cool wall was presented. The morphology and structure of TiO2 powder, hot wall scale and cool wall scale by condensation were characterized by TEM, SEM, Optical microscopy and XRD, respectively.
