摘要： 在湿化学法制备a-Al2O3微粉过程中，引入a-Al2O3, a-Fe2O3等籽晶，可以控制a-Al2O3粉末的粒度及颗粒形状，增加相变速度，降低晶相转换温度，因而可以降低水热法制备a-Al2O3微粉的成本，使水热法制备氧化铝实现工业生产成为可能. 本文结合笔者的研究工作，总结了国内外在此方面的研究情况，就籽晶在水热法制备a-Al2O3微粉过程中所起的作用作一综合评述.
关键词: 籽晶, 水热法, a-Al2O3 微粉, 晶形转变
Abstract: There is currently large amount of residual coal gas in iron-steel plants which should be used in the future, otherwise it will cause energy loss and environmental pollution. It is suggested in this paper that the coal gas can be used to produce electricity or chemicals. The situation is also discussed when new technologies such as smelting reduction process and continuous casting process are adopted.
Key words: iron steel plant, coal gas, methanol, electricity
