The invention provides a high-temperature ceramic hollow roller and a preparation method thereof. The hollow roller bar comprises a roller bar body formed by a hollow part inside the hollow roller bar and a bar wall. Basic raw materials for preparing the stick wall are composed of 25-30% of alpha-aluminum oxide powder, 10-15% of zirconium silicate powder, 10-15% of silicon nitride powder, 10-15% of sericite powder, 10-15% of feldspar powder, 10-15% of ball clay powder, 15-20% of soft kaolin powder and 0.16-0.21% of methyl cellulose dry powder, and in the stick wall, the raw materials are evenly mixed to form the stick wall. A reinforcing structure made of polycrystalline mullite fibers is further arranged, and the reinforcing structure and the rod wall are integrated into a whole. On the premise that the weight of the high-temperature ceramic hollow roller is not increased, the structural strength and the fracture resistance of the high-temperature ceramic hollow roller are improved.
本发明提供了一种高温陶瓷空心辊棒及制备方法。所述空心辊棒包括其内部的空心部分和棒壁共同构成的棍棒本体，按质量百分比，制备所述棒壁的基本原材料由25～30％的α‑氧化铝粉末、10～15％的硅酸锆粉末、10～15％的氮化硅粉末、10～15％的绢云母粉末、10～15％的长石粉末、10～15％的球粘土粉末、15～20％的软质高岭土粉末、0.16～0.21％的甲基纤维素干粉组成，在所述棒壁内，还设置有由多晶莫来石纤维制成的增强结构，所述增强结构与所述棒壁融为一体。本发明能够在不增加高温陶瓷空心辊棒重量的前提下，提高其结构强度和抗折断性能。
