Multi-layer tungsten metallization aluminum oxide special-shaped part for HTCC and preparation method of multi-layer tungsten metallization aluminum oxide special-shaped part
The invention discloses a multi-layer tungsten metallized alumina special-shaped part for HTCC and a preparation method thereof, the preparation method comprises the following main steps: forming raw ceramic, i.e., preparing an alumina raw ceramic chip into required raw ceramic according to a pre-design; co-firing: carrying out high-temperature co-firing on the raw ceramic, raising the temperature from room temperature to 500-600 DEG C at the speed of 0.75-2.75 DEG C/min, carrying out heat preservation for 2-4 hours, and introducing nitrogen in the whole working section; the temperature is increased to 1500-1650 DEG C at the speed of 1-3 DEG C/min, heat preservation is conducted for 1.5-3 h, then natural cooling is conducted along with the furnace, and mixed gas of nitrogen and wet hydrogen with water vapor is introduced into the working section in the whole process. By means of the preparation method, carbon residues of the multilayer tungsten metallized aluminum oxide special-shaped part are obviously improved, and the performance of the final material is guaranteed.
本发明公开了一种用于HTCC的多层钨金属化氧化铝异形件及其制备方法，该制备方法主要工序有生瓷成型，即将氧化铝生瓷片按预先设计制成所需的生瓷；共烧，将所述生瓷进行高温共烧，从室温以0.75‑2.75℃/min升至500‑600℃，保温2‑4h，此工作段全程通入氮气；再以1‑3℃/min升温至1500‑1650℃，保温1.5‑3h后随炉自然冷却，此工作段全程通入氮气与带水蒸气的湿氢的混合气体。经过该制备方法使得多层钨金属化氧化铝异形件的碳残留得到了明显的改善，保证了最终材料的性能。
