Preparation method of small ceramic tube based on isostatic pressing
The invention belongs to the technical field of small-sized ceramic tubes, and particularly relates to a preparation method of a small-sized ceramic tube based on isostatic pressing, which comprises the following steps: adding activated aluminum oxide and polyvinyl alcohol into methanol, uniformly stirring, then adding into a ball mill, and carrying out constant-temperature ball milling treatment for 1-2 hours to obtain slurry; placing the slurry in a mold, carrying out microwave reaction for 30-60 minutes, and then boosting to form a rough blank; the rough blank is subjected to constant-temperature sintering for 2-4 h and then subjected to ultrasonic soaking in a titanium source for 1-3 h, the rough blank is taken out, dried, sealed, wrapped and subjected to constant-temperature standing for 20-40 min, standing is conducted for 10-20 min after cooling, and a pre-coated blank is obtained; and carrying out isostatic pressing treatment on the pre-coated green body for 3-5 hours, and then sintering to obtain the small ceramic tube. According to the invention, the process defects of a small ceramic tube are overcome, a titanium dioxide-aluminum oxide composite wrapping system is formed by utilizing a vaporization infiltration system of titanium dioxide, and titanium dioxide is used as an inner core point, so that the overall mechanical property is improved.
本发明属于小型陶瓷管技术领域，具体涉及一种基于等静压的小型陶瓷管的制备方法，包括：将活性氧化铝与聚乙烯醇加入至甲醇中搅拌均匀，然后加入球磨机中恒温球磨处理1‑2h，得到浆料；将浆料放置在模具中微波反应30‑60min，然后升压形成粗坯；将粗坯进行恒温烧结2‑4h，然后钛源中超声浸泡1‑3h，取出烘干并密封包裹恒温静置20‑40min，冷却后静置10‑20min，得到预镀膜坯体；将预镀膜坯体等静压处理3‑5h，然后烧结处理，得到小型陶瓷管。本发明解决了小陶瓷管的工艺缺陷，利用二氧化钛的汽化内渗体系，形成二氧化钛‑氧化铝的复合包裹体系，并以二氧化钛作为内核点，提升整体的机械性能。
