The study for the eutectic of the mineral compounds and the modification of the simple simple silica in the coal ashes The coal ashes are consist some clay minerasls and a simple silica, and the fusion temperature are fefined the softening point, the fusion point, and the pour point.For instance, the softening point for the ashes is from 1200 ﾟC to 100ﾟC,and fusion point is from 1300ﾟC to 1400ﾟC .But, in the coal ashes , there are not the chemical, or mineral compounds, that has a such low fusion temperature.So the investigation research and experimental study were being into practice, for the softening point and the fusion point of the coal ashes. The results of the study, we were obtained interesting results that the softening point is the mpdification temperature of the simple silica, and the fusion point is the eutectic temperature of the mineral matters in the coalashes.
