Ceramic packaging shell material capable of being sintered at low temperature
The invention discloses a ceramic packaging shell material capable of being sintered at low temperature. The ceramic packaging shell material comprises the following components: silicon dioxide, a mixed fluxing agent, borax, barium oxide, potassium oxide, a coloring agent and aluminum oxide. According to the material, a mixed fluxing agent composed of a mixture of lithium carbonate and calcium fluoride in a mass ratio of 4: (1-2) is adopted, and a mode of grinding, drying and then grinding is adopted in the preparation process, so that the sintering temperature in the preparation process of the ceramic packaging shell material is remarkably reduced, sintering can be completed at 650-680 DEG C, and the energy consumption is reduced.
本发明公开了一种可低温烧结的陶瓷封装外壳材料，包括以下成分：二氧化硅、混合助熔剂、硼砂、氧化钡、氧化钾、着色剂和氧化铝。该材料通过采用碳酸锂和氟化钙质量比为4：（1‑2）的混合物组成的混合助熔剂并在制备过程中采用研磨烘干再研磨的方式，本发明的陶瓷封装外壳材料制备过程中的烧结温度显著降低，在650‑680℃就可以完成烧结，减少了能耗。
