Silicon dioxide ceramic core for manufacturing turbofan engine and preparation method of silicon dioxide ceramic core
The invention discloses a silicon-based ceramic core for manufacturing a turbofan engine and a preparation method thereof, the ceramic core is prepared from a base material and a mineralizer, the base material is quartz glass powder and borosilicate glass powder, and the mineralizer is alumina powder and zirconium silicate powder; wherein the quartz glass powder accounts for 70%-95% by weight, the borosilicate glass powder accounts for 1%-10% by weight, the alumina powder accounts for 1%-10% by weight, and the zirconium silicate powder accounts for 1%-10% by weight. The composite material is prepared through gel casting. By adjusting the formula of the raw material powder of the ceramic core and combining a gel-casting method, the ceramic core with high strength and small shrinkage rate is prepared and can be used for manufacturing turbofan engines, the sintering schedule is simple, the sintering period is short, and industrial production is facilitated.
本发明公开了一种用于制造涡扇发动机的硅基陶瓷芯及其制备方法，该陶瓷芯由基料和矿化剂制成，所述基料为石英玻璃粉和硼硅酸盐玻璃粉，所述矿化剂为氧化铝粉和硅酸锆粉；其中按重量百分比计，石英玻璃粉70％～95％，硼硅酸盐玻璃粉1％～10％，氧化铝粉1％～10％，硅酸锆粉1％～10％；通过凝胶注模成型制备得到。本发明通过调整陶瓷芯的原料粉配方，结合凝胶注模法，制得强度高、收缩率小的陶瓷芯，可用于制造涡扇发动机，烧结制度简单，烧结周期短，有利于工业化生产。
