矿物材料及其纳米技术改造

根据矿物的表面特征及应用要求选择合适的分散剂和分散方法进行矿物纤维的分散可以实现矿物纤维纳米化。另外，开发纳米插层及涂层技术在蛭石、云母等层状矿物上的应用，研究新型纳米孔材料及矿物纳米复合材料等不仅技术上可行，而且具有广阔的发展前景。矿物纳米材料的开发是低成本制备纳米材料的重要突破口之一，对于实现纳米材料的产业化和普及化具有强有力的推动作用。开发矿物材料有利于人类社会的可持续发展。

MINERAL MATERIALS AND NANO-TECNOLOGY APPLICATION

The principal characteristics of mineral materials were analyzed.The technological feasibility, application potentials and the significance of nano technology application in mineral materials were explained.Test results show that the combination of mechanical grinding, dispersing and surface modifying benefits the preparation of mineral nano powders.Mineral fibers can be split to nano diameter scales at the condition of proper selection of dispersing agents and methods according to the surface features and utilization requirements.Nano intercalation or film coating of layered minerals such as vermiculite and mica as well as manufacturing of mineral nano pore materials and nano composites can also be practicable and have vast foreground.The development of mineral nano materials is probably one of the important means to prepare nano materials at low costs and is favorable to the promotion of the nano materials industrialization and to the sustainable development of human society.
