Zusammenfassung: | The invention provides a manufacturing method of high-temperature resistant ceramic particles with a golf surface appearance feature, belonging to the refractory material technical field. The manufacturing method comprises the following steps: taking alumina powder or calcium hexaluminate powder or spinel powder or mullite powder or bauxite raw meal powder and the like as raw materials; alletizing the powder with smaller granularity (alumina powder or calcium hexaluminate powder or spinel powder or mullite powder or bauxite raw meal powder and the like) into balls of 0.20-25mm diameter by a rolling ball forming mill, controlling granularity size of blank bodies by added water quantity and ball forming time, wrapping raw meal powder with greater granularity of 0.05-8mm (alumina powder or calcium hexaluminate powder or spinel powder or mullite powder or bauxite raw meal powder and the like) on the surface of the type of pellets by a rolling pelletization method to obtain the corresponding high-temperature resis |
