Alumina Ceramic Process Flow

Alumina Ceramic Process Flow
With the continuous development of technology, precision ceramics have been widely used in various fields such as chemical industry, machinery manufacturing, biomedicine, etc., and gradually expand the scope of application with the improvement of performance. The following Kezhong Ceramics will introduce you to the detailed production of precision ceramics. Process flow.

The production process of precision ceramics mainly uses alumina powder as the main raw material and magnesium oxide as the additive, and uses dry pressing to sinter to produce the precision ceramics required for the test. The specific process flow.

The production of precision ceramics must first take the material, the aluminum oxide, zinc dioxide and magnesium oxide required for the experiment, respectively calculate the weight of different grams, and use the balance to weigh and take the material in detail.

In the second step, the PVA solution is configured according to different material ratios.

In the third step, the PVA solution of the raw materials prepared in the first and second steps is mixed and ball-milled. The time of this process is generally about 12h, and the rotation speed of the ball-milling is ensured at 900r/min, and the ball-milling work is carried out with distilled water.

The fourth step is to use a vacuum drying oven to dehydrate and dry the prepared raw materials, and keep the working temperature at 80-90 °C.

The fifth step is to granulate first and then shape. The raw materials dried in the previous step are pressed on the hydraulic jack.

The sixth step is to sinter, fix and shape the alumina product.

The last step is the polishing and polishing of precision ceramic products. This step is divided into two processes. First, use a grinder to remove most of the excess large particles of the ceramic product, and then use fine sandpaper to finely rub some areas of the ceramic product. And decoration, and finally polishing the entire precision ceramic product, so far the precision ceramic product is completed.
