Alumina ceramic structural member and preparation method thereof
The invention belongs to the technical field of ceramic structural parts, and particularly relates to an aluminum oxide ceramic structural part and a preparation method thereof. According to the preparation method of the aluminum oxide ceramic structural part, provided by the invention, aluminum oxide slurry is subjected to tape casting in advance, and a green body sheet is prepared; the preparation method comprises the following steps: sintering an alumina ceramic main body, further pre-burying a polyvinyl butyral filling body into a green body sheet, and after the sintering step, volatilizing the polyvinyl butyral filling body to form a channel or a through hole in a specific position of the alumina ceramic main body, so as to obtain the integrally formed alumina ceramic structural member with excellent product performance. Furthermore, the aluminum oxide ceramic structural member prepared by the preparation method can be used as an integrated aluminum oxide ceramic finished product after simple treatment, and has the advantages of simple preparation process, low cost and relatively high efficiency, and the prepared aluminum oxide ceramic structural member is high in product yield.
本申请属于陶瓷结构件技术领域，具体涉及氧化铝陶瓷结构件及其制备方法。本申请提供的氧化铝陶瓷结构件制备方法中，通过预先将氧化铝浆料进行流延成型，制备生坯片；并进一步将聚乙烯醇缩丁醛填充体预埋于生坯片中，在烧结步骤过后，聚乙烯醇缩丁醛填充体挥发，使在氧化铝陶瓷主体的特定位置形成通道或通孔，以得到产品性能优异的一体成型的氧化铝陶瓷结构件。进一步地，本申请制备方法制备的氧化铝陶瓷结构件经过简单处理即可用作一体氧化铝陶瓷成品，具有制备过程简单，成本低且效率较高的优点，且制备得到的氧化铝陶瓷结构件，产品良率高。
