MODIFIED CALCIUM ALUMINATE COMPOUND AND PRODUCTION METHOD THEREFOR

Prior art does not disclose a method for modifying the surface of a calcium aluminate compound, much less a method for controlling the particle size of a calcium aluminate compound. The present invention provides a novel method for producing a calcium aluminate compound having a modified surface. The present invention provides: a method for producing a modified calcium aluminate compound, which method is characterized by modifying the surface of the calcium aluminate compound by irradiating the calcium aluminate compound dispersed in an organic dispersion medium with a femtosecond laser; and amodified calcium aluminate compound which is characterized by being obtained by the method, and which has at least one of an OH group, a CO group, a CH group, and an NH group. 现有文献中尚未记载对铝酸钙化合物的表面进行改性的方法，而且也未记载任何控制铝酸钙化合物的粒径的方法。本发明提供种经表面改性的铝酸钙化合物的新的制备方法。本发明提供种改性铝酸钙化合物的制备方法，其特征在于，对分散于有机分散介质中的铝酸钙化合物照射飞秒激光从而对所述铝酸钙化合物的表面进行改性；还提供种由上述方法得到的改性铝酸钙化合物，其特征在于，具有OH基、CO基、CH基、NH基中的任意者以上。
