铝酸酯对电气石的表面改性及其表征

摘要

The surface modification of the tourmaline powder with an aluminic ester was discussed. The experimental results showed that the activation index of aluminic ester modified tourmaline powder reached to 97% when 1.5 % aluminic ester reacted with tourmaline powder at 70 t for 0.5 h in benzene; and the aluminic ester modified tourmaline had an excellent hydrophobic property, but with no change in crystal configuration of tourmaline.%本文以铝酸酯为改性剂对电气石的表面改性反应进行了探讨,结果表明,以苯为溶剂,铝酸酯的用量为电气石的1.5％,70℃下搅拌0.5 h,可使改性电气石的活化指数达到97％；所得铝酸酯改性电气石表面具有较强的疏水特性,而没有影响其晶体结构.
