摘要: 通过热重-差示扫描量热分析法和旋转法对陕西略阳玄武岩原矿的化学成分、熔化过程中析晶的上下限温度、熔化的黏度-温度变化等物理化学性能作了定性的分析与研究.确定出该矿区的玄武岩可以用来制备玄武岩连续纤维,并进一步确定出略阳玄武岩样品析晶的上限温度为1 271℃.同时根据样品的黏度-温度变化规律最终得出样品的最佳成形温度为1 320～1 340℃.利用这些数据可为进一步研究开发和合理利用玄武岩资源提供理论依据.Abstract: The physical and chemical properties of the basalts, including chemical components, the upper and lower limits of crystallization temperature in basalt melting process, viscositytemperature variation in melting, etc. are measured qualitatively and studied by thermogravimetryscanning differential thermal analysis and rotation methods. The results show that the upper limit of crystallization temperature and optimum formation temperature for basalts from Shaanxi Lueyang are 1271℃ and 1320～1340℃ respectively. The results from the study also show that the basalts from this area can be used to produce the basalt continuous fibers and provide the theoretical bases for further development and reasonable utilization of basalt resources.
