Ceramic-metal sealing ceramic chip prepared by tape casting method
The invention discloses a ceramic metal sealing ceramic chip prepared by a tape casting method. A sealing butt joint process flow comprises the following steps: (1) drying inorganic powder at 110 DEGC for 4 hours; (2) using a ball mill, weighing the powder as required, and performing crushing to obtain glass powder to be sealed; and (3) adding the prepared glass powder into a ball milling tank according to a pulping formula to prepare glass pulp. According to the ceramic metal sealing ceramic chip prepared by the tape casting method, different from the prior art, the ceramic metal sealing ceramic chip prepared by the tape casting method is suitable for high-temperature use, uniform in density, suitable for cutting and processing, good in fit plating with a plane, good in sealing propertyafter sintering and high in chemical stability in an oxidizing gas environment; and the thermal expansion amount is uniformly matched with each part of a solid oxide fuel cell, and the failure causedby local thermal expansion amount difference is avoided, so that the air tightness, the insulativity, the thermal stability and the chemical stability of the solid oxide fuel cell are greatly improved.
本发明公开了一种流延方法制备的陶瓷‑金属密封陶瓷片，其密封对接工艺流程如下：(1)无机粉体在110℃下干燥4小时；(2)使用球磨机，按需求称量粉体，粉碎后得到待封接玻璃粉；(3)将制好的玻璃粉按照制浆配方，加入球磨罐制取玻璃浆；流延方法制备的陶瓷‑金属密封陶瓷片，区别于现有技术，采用流延法制备的适合高温使用的玻璃密封材料，密度均匀，适合裁剪加工，与平面贴合镀好，烧结后密封性好，且在氧化气体环境中化学稳定性能高，其热膨胀量与固体氧化物燃料电池的各部分均匀匹配，不会因局部热膨胀量差异而失效，从而大大提高了固体氧化物燃料电池的气密性、绝缘性、热稳定性及化学稳定性。
