摘要
对我国浙南温州渡船头伊利石矿的热膨胀性及其机理进行了研究。结果表明，在室温－１３００℃温度区间内，其热膨胀性表现为先收缩后膨胀再收缩的特性，其中在１３００℃之后不同类型矿石的热膨胀性亦不同。伊利石的这种热膨胀性与其在加热过程中晶体结构及物相的变化密切相关。伊利石矿中的铁质杂质矿物对其热膨胀性有很大影响。
The thermal swellability and its mechanisms of illite from Duchuantou in Zhejiang province were discussed.The following results have obtained by the swell test 1) Between 20℃ to 1300℃,the illite'thermal swellability will be shown three processes: from the contracting process to the swelling process then the contracting process again. 2) The thermal swellability of illite above mentioned iS closely related with its crystal structures and changes of phases during heating. 3) Different type of illite ore has different thermal swellability after 1 130℃, mainly caused by a small amount of ferriferous minerals.
