The invention provides a casting sheet for a ceramic shell. The casting sheet comprises the following components in parts by mass: 90-95 parts of aluminum oxide; 0.1 to 2 parts of a coloring agent; 3 to 9.9 parts of a sintering aid; the aluminum oxide comprises fine-particle-size aluminum oxide and coarse-particle-size aluminum oxide, and the particle size of the fine-particle-size aluminum oxide is 0.4-1.0 micron; the particle size of the coarse-particle-size aluminum oxide is 2-5 microns, and the fine-particle-size aluminum oxide accounts for 20-50% of the total aluminum oxide. 1-10 parts of an adhesive; the casting sheet is softer and convenient to process, so that the side interlayer binding force of the casting sheet is greatly increased, and the side surface of the processed ceramic shell is smooth.
本发明提供了一种用于陶瓷外壳的流延片，包括如下质量份数的各成份：氧化铝：90‑95份；着色剂：0.1‑2份；助烧剂：3‑9.9份；所述氧化铝包括细粒径氧化铝和粗粒径氧化铝，所述细粒径氧化铝的粒径为0.4微米至1.0微米；所述粗粒径氧化铝的粒径为2微米至5微米，所述细粒径氧化铝占总的氧化铝的20％至50％。粘合剂：1‑10份；使得流延片更软，便于加工，使得流延片侧层间结合力大大增加，并且使得加工后得到的陶瓷外壳的侧面光滑。
