Preparation method of silicon dioxide ceramic
The invention relates to a preparation method of silicon dioxide ceramic, which comprises the following steps: powder preparation: adding silicon dioxide powder into absolute ethyl alcohol, stirring, adding a sintering aid, mixing and drying to obtain silicon dioxide mixed powder coated with the sintering aid; molding a green body: carrying out jet printing molding on the obtained silicon dioxide mixed powder through a binder, and then baking and curing to obtain a silicon dioxide green body; degreasing and dipping: degreasing the obtained silicon dioxide green body, adding an inorganic binder after degreasing, and then carrying out vacuum dipping; sintering the green body, namely sintering the silicon dioxide green body subjected to vacuum impregnation at high temperature to obtain a high-performance silicon dioxide ceramic product. By modifying the silicon dioxide powder and impregnating the green body with the inorganic binder, the strength of the silicon dioxide ceramic is improved, and the problem that the silicon dioxide ceramic product is easy to crack is solved, so that the performance of the sintered silicon dioxide ceramic is improved.
一种二氧化硅陶瓷的制备方法，包括以下步骤：粉末制备：将二氧化硅粉末加入无水乙醇搅拌后加入烧结助剂，混合干燥后得到包覆有烧结助剂的二氧化硅混合粉末；生坯成型：将获得的二氧化硅混合粉末通过粘结剂喷射打印成型后烘烤固化，获得二氧化硅生坯；脱脂浸渍：将获得的二氧化硅生坯进行脱脂，脱脂结束后加入无机粘结剂，随后进行真空浸渍；坯体烧结：将真空浸渍后的二氧化硅坯体进行高温烧结，获得高性能的二氧化硅陶瓷制品。通过对二氧化硅粉末进行改性，采用无机粘结剂浸渍生坯的方式，提高二氧化硅陶瓷的强度，改善二氧化硅陶瓷制品易开裂的问题，从而提高二氧化硅陶瓷烧结后的性能。
