Microcrystalline glass oxide ceramic product based on 3DP molding and preparation method thereof
The invention discloses a microcrystal glass oxide ceramic product based on 3DP molding and a preparation method thereof, and relates to the technical field of oxide ceramics. The preparation method provided by the invention comprises the following steps: S1, carrying out ball milling and uniform mixing on 90-100 parts by mass of oxide ceramic powder with grain composition and 0-10 parts by mass of a sintering aid to obtain printing powder; s2, the printing powder is subjected to 3DP forming, a green body is prepared, the green body is degreased and sintered, and a ceramic body is obtained; s3, the ceramic body and microcrystalline glass powder are subjected to infiltration treatment, gaps of the ceramic body are filled with microcrystalline glass in a molten state, and the microcrystalline glass oxide ceramic product is prepared. The oxide ceramic powder with grain composition is used as a raw material, so that the bulk density and the strength of the green body are improved; a glass ceramic infiltration process is adopted, so that gaps of a ceramic body are filled with glass ceramic in a molten state, and finally the glass ceramic oxide ceramic product with good mechanical properties is prepared.
本发明公开了一种基于3DP成型的微晶玻璃氧化物陶瓷制品及其制备方法，涉及氧化物陶瓷技术领域。本发明提供的制备方法，包括步骤：S1、按质量份计，将颗粒级配的氧化物陶瓷粉体90‑100份、烧结助剂0‑10份进行球磨混匀，得到打印粉体；S2、将所述打印粉体进行3DP成型，制备生坯，并对所述生坯进行脱脂、烧结，得到陶瓷体；S3、将所述陶瓷体与微晶玻璃粉体进行熔渗处理，使微晶玻璃在熔融状态下填充所述陶瓷体的空隙，制得微晶玻璃氧化物陶瓷制品。本发明采用颗粒级配的氧化物陶瓷粉体作为原料，有助于提高坯体的堆积密度和强度；采用微晶玻璃熔渗的工艺，使微晶玻璃在熔融状态下填充陶瓷体的空隙，最终制得具有良好力学性能的微晶玻璃氧化物陶瓷制品。
