Special sintering shrinkage regulator for silicon-based ceramic core and preparation method of special sintering shrinkage regulator
The invention relates to a special sintering shrinkage regulator for a silicon-based ceramic core and a preparation method of the special sintering shrinkage regulator, and belongs to the technical field of ceramic core manufacturing. The special sintering shrinkage regulator for the silicon-based ceramic core is prepared from the following components in parts by weight: 10 to 30 parts of kyanite powder, 20 to 45 parts of cristobalite powder, 10 to 40 parts of mullite powder, 10 to 20 parts of activated aluminum oxide powder, 0 to 10 parts of monatomic silicon powder, 0 to 10 parts of silicon carbide powder and 0 to 10 parts of silicon nitride powder. The preparation method has the beneficial effects that the regulator can be added when the silicon-based ceramic core is prepared on the premise that the performance of the ceramic core is hardly changed, the sintering size of the ceramic core is freely adjusted, and the situation that the performance of the ceramic core is sacrificed in order to guarantee sintering shrinkage is avoided.
本发明涉及一种硅基陶瓷型芯专用烧结收缩调节剂及其制备方法，属于陶瓷型芯制造技术领域。所述硅基陶瓷型芯专用烧结收缩调节剂的成分包括由如下重量份数的组分组成：蓝晶石粉10～30份、方石英粉20～45份、莫来石粉10～40份、活性氧化铝粉10～20份、单质硅粉0～10份、碳化硅粉0～10份和氮化硅粉0‑10份。有益效果：可以在几乎不改变陶瓷型芯性能的前提下，在制备硅基陶瓷型芯时加入该调节剂，对陶瓷型芯的烧结尺寸进行自由调整，避免为了保证烧结收缩而牺牲陶瓷型芯的性能。
