Apatite slurry and process for the preparation thereof

本发明提供了磷灰石二级颗粒能实质上完全再分散的一种磷灰石泥浆，并提供了其制造方法。本发明磷灰石泥浆的特征在于，它是磷灰石颗粒分散于水相溶性有机溶剂中而得到的磷灰石泥浆，其分散度为磷灰石颗粒的平均粒径在1微米以下并且实质上不存在3微米以上的颗粒。另外，本发明磷灰石泥浆的制造方法的特征在于，把磷灰石颗粒分散于水相溶性有机溶剂中的磷灰石泥浆供给到搅拌磨内，并粉碎和分散处理到实质上不存在3微米以上颗粒的分散度。 An apatite slurry prepared by re-dispersing secondary particles of apatite substantially complet...

Zusammenfassung:	本发明提供了磷灰石二级颗粒能实质上完全再分散的一种磷灰石泥浆，并提供了其制造方法。本发明磷灰石泥浆的特征在于，它是磷灰石颗粒分散于水相溶性有机溶剂中而得到的磷灰石泥浆，其分散度为磷灰石颗粒的平均粒径在1微米以下并且实质上不存在3微米以上的颗粒。另外，本发明磷灰石泥浆的制造方法的特征在于，把磷灰石颗粒分散于水相溶性有机溶剂中的磷灰石泥浆供给到搅拌磨内，并粉碎和分散处理到实质上不存在3微米以上颗粒的分散度。 An apatite slurry prepared by re-dispersing secondary particles of apatite substantially completely; and a process for the preparation thereof. The apatite slurry is one comprising apatite particles dispersed in an organic solvent compatible with water and characterized by having such a degree of dispersion that the mean diameter of the apatite particles is 1 'mu'm or below and that any apatite particle having a diameter of 3 'mu'm or above is substantially absent. The process is characterized by feeding the above-specified apatite slurry into an agitating mill and conducting the milling and dispersion up to such a degree of dispersion that any apatite particle having a diameter of 3 'mu'm or above is substantially absent.
