Tungsten metallization-multilayer alumina black porcelain substrate and preparation method thereof
The invention discloses a tungsten metallization-multilayer aluminum oxide black porcelain substrate and a preparation method thereof, the main process of the preparation method comprises the following steps: providing a laminated body, and printing tungsten slurry on the front and back surfaces of a green porcelain tape on the top layer of the laminated body; cutting the laminated body to obtain a green body; the green body is subjected to high-temperature co-firing, specifically, after reaction equipment is vacuumized, mixed gas of nitrogen and wet hydrogen is introduced, the temperature is increased to 500-600 DEG C at the speed of 1-3 DEG C/min, and heat preservation is conducted for 1-3 h; the temperature is increased to 900-1000 DEG C at the speed of 1-3 DEG C/min, and heat preservation is conducted for 20 And finally, the temperature is increased to 1500-1650 DEG C at the speed of 1-2 DEG C/min, heat preservation is conducted for 1-3 h, and natural cooling along with Through the process improvement in the invention, the warping problem of the prepared tungsten metallization-multilayer aluminum oxide black porcelain substrate is obviously improved, and the black porcelain substrate has high flatness.
本发明公开了一种钨金属化‑多层氧化铝黑瓷基片及其制备方法，该制备方法主要工艺有：提供层叠体，所述层叠体顶层的生瓷带的正反两面均印刷有钨浆；生切所述层叠体，获得生坯；将所述生坯高温共烧，其中，高温共烧的工艺具体为反应设备中抽真空后，通入氮气和湿氢的混合气体，以1‑3℃/min升至500‑600℃，保温1‑3h；再以1‑3℃/min升至900‑1000℃，保温20‑60min；最后以1‑2℃/min升温至1500‑1650℃，保温1‑3h，随炉自然冷却。通过本发明中的工艺改进，使得制得的钨金属化‑多层氧化铝黑瓷基片的翘曲问题得到明显改善，黑瓷基片具有高平整度。
