研究了湖北团风蛭石矿的产状、物质组成、膨胀性能及其膨胀蛭石的加工方法。结果表明 ,该蛭石矿是由角闪黑云长石片麻岩经热液蚀变而成。蛭石矿物实际上是水黑云母。蛭石在 6 0 0℃时焙烧 1分钟能够达到最大膨胀率 3.3倍。通过对民采膨胀蛭石产品进行研究 ,提出了合理的加工方法 ,能够提高产品质量 ,扩大产品的应用范围。

Study on Mineralogy and Thermal Expansibility of Vermiculit from Tuanfong Peng Hua\ Peng Changqi\ Wang QingyanThrough study on the attitudy of tratum,mineral,expansibility and processing methods of vermiculit in Tuanfong ,it had been found that thermoliquor eroded biotite arkosic gneiss to form vermiculit ore. Vermiculit is hydrobiotite. Vermiculit baked can get maximal expance rate (3.3 times)for a minute at 600 ℃. Study on expanded vermiculit product from the personal product, we provide the new processing program to improve the product quality and increase application range.vermiculit of Tuan fong;\ expanded rate;\ processing program of expanded vermiculit Peng Hua: Lect., Collge of Resources and Environment, WUT, Wuhan 430070, China.
