The invention relates to the technical field of crucibles, in particular to a corrosion-resistant crucible for polycrystalline silicon ingot casting and a preparation method thereof.The crucible comprises a heat dissipation base, at least one reinforcing rib net layer matched with the contour of the crucible is arranged in the inner wall of a crucible body, and the crucible body is made of new mixed ceramic slurry; according to the corrosion-resistant crucible for polycrystalline silicon ingot casting, more efficient heat conduction capacity can be obtained, the problem that the heat dissipating capacity difference between the side wall and the bottom is large can be solved through the heat dissipating structure at the bottom, and meanwhile the mechanical property and heat dissipating performance of the crucible can be improved through the reinforcing rib net layer and the new mixed ceramic slurry; and moreover, the corrosion of acid and alkali residues in the silicon material in the ingot casting process to the crucible can be effectively blocked based on the new mixed ceramic slurry, and the corrosion resistance of the crucible can be improved, so that the overflow rate of the crucible is reduced, the ingot casting efficiency is favorably improved, the production cost is reduced, and the method is suitable for large-scale industrial production.
本发明涉及坩埚技术领域，具体为多晶硅铸锭用耐腐蚀坩埚及其制备方法，该坩埚包括散热底座，坩埚本体内壁中设有至少一层与坩埚轮廓相互契合的强筋网层，所述坩埚本体采用混合陶瓷新料浆制成；该多晶硅铸锭用耐腐蚀坩埚，能够获得更加高效的导热能力，并且底部的散热结构能够降低侧壁与底部散热量差异较大的问题，同时强筋网层与混合陶瓷新料浆均能够提高坩埚的力学性能和散热性，并且能够基于混合陶瓷新料浆能够有效地阻隔铸锭过程中硅料中的酸碱残留对坩埚的侵蚀，能够提高坩埚的耐腐蚀性能，从而减少坩埚的溢流率，有利于提高铸锭效率，降低生产成本，适用于大规模工业生产。
