Double-layer thick film ceramic containing micro-channels and preparation method thereof
The invention provides a preparation method of double-layer thick-film ceramic containing a micro-channel, which comprises the following steps: mixing the following components in parts by weight: 39.57-59.57 parts of aluminum oxide, 30-50 parts of aluminum nitride, 10 parts of cordierite and 0.43 part of magnesium oxide, and uniformly stirring the components to obtain a main material; mixing and uniformly stirring the following components in parts by weight: 1 part of PVB and 25 parts of absolute ethyl alcohol until no obvious white particles exist to obtain a PVB solution, and standing the mixture for 24 hours for later use; mixing and ball-milling the main material, castor oil, a PVB solution and absolute ethyl alcohol to prepare ethanol-based aluminum oxide slurry with the solid phase content of 50%; carrying out tape casting on the ethanol-based alumina slurry to obtain a thick film green body; cutting the thick film green bodies are cut, and laminating two cut thick film green bodies with the same size and carrying out temperature isostatic pressing treatment; and sintering the thick-film green body subjected to the temperature isostatic pressing treatment in a high-temperature atmosphere furnace to obtain the double-layer thick-film ceramic with the micro-channel. The preparation method has the advantages of being low in cost, high in efficiency, simple in process and easy to control.
本发明提供了一种含有微流道的双层厚膜陶瓷的制备方法，包括以下步骤：以重量份计，氧化铝39.57‑59.57份，氮化铝30‑50份，堇青石10份和氧化镁0.43份，混合后搅拌均匀配得主料；以重量份计，PVB1份，无水乙醇25份，混合后搅拌均匀直至无明显白色颗粒为止得到PVB溶液，静置24小时后备用；将主料、蓖麻油、PVB溶液和无水乙醇混合球磨，配置得到固相含量为50%的乙醇基氧化铝浆料；对乙醇基氧化铝浆料进行流延，得到厚膜生坯；对厚膜生坯进行裁剪，将裁剪所得的两个大小相等的厚膜生坯叠在一起后进行温等静压处理；将温等静压处理后的厚膜生坯放在高温气氛炉里烧结以得到带有微流道的双层厚膜陶瓷。本发明的制备方法具有成本低，效率高，工艺简单且容易控制的有点。
