Ceramic packaging shell material with low shrinkage rate
The invention discloses a ceramic packaging shell material with a low shrinkage rate. The ceramic packaging shell material is prepared from the following components in percentage by weight: 8-15% of silicon dioxide, 4-7% of magnesium oxide, 0.5-0.8% of rare earth oxide, 0.8-1.5% of barium oxide, 0.8-1.2% of potassium oxide, 2-8% of A colorant and the balance of aluminum oxide. The shrinkage rate of the ceramic packaging shell material can be remarkably reduced by adjusting the formula of the ceramic packaging shell material, especially by adopting rare earth oxide composed of a mixture of lanthanum oxide, cerium oxide and yttrium oxide, and the radial sintering shrinkage rate of the ceramic packaging shell material after tabletting is lower than 0.05%.
本发明公开了一种低收缩率的陶瓷封装外壳材料，由以下重量百分比的成分组成：二氧化硅8‑15%、氧化镁4‑7%、稀土氧化物0.5‑0.8%、氧化钡0.8‑1.5%、氧化钾0.8‑1.2%、着色剂2‑8%和氧化铝余量。本发明通过调整陶瓷封装外壳材料的配方，尤其是采用氧化镧、氧化铈和氧化钇的混合物组成的稀土氧化物可以显著降低陶瓷封装外壳材料的收缩率，本发明的陶瓷封装外壳材料压片后径向烧结收缩率低于0.05%。
