Ceramic metallization slurry and preparation method and application thereof
The invention relates to the technical field of brazing pretreatment materials, and in particular, relates to ceramic metallization slurry and a preparation method and application thereof. The ceramicmetallization slurry is mainly prepared from the following raw materials in parts by mass: 3-30% of metal ultrafine powder, 5-25% of metal oxide ultrafine powder, 15-30% of an organic solvent, 15-45%of an organic additive, and the balance being ultrafine palladium powder. The metal ultrafine powder mainly comprises any one or more of Ti ultrafine powder, Pt ultrafine powder, Zr ultrafine powderor Ag ultrafine powder; the metal oxide ultrafine powder mainly comprises any one or more of Y2O3 ultrafine powder, CaO ultrafine powder, Al2O3 ultrafine powder, MgO ultrafine powder, MnO ultrafine powder or ZrO2 ultrafine powder. According to the ceramic metallization slurry, the adhesive force between a metallization layer formed by coating the surface of a ceramic device with the ceramic metallization slurry and sintering and the ceramic device is large, and a formed metallization layer is not prone to cracking and warping.
本发明涉及用于钎焊预处理材料技术领域，具体涉及一种陶瓷金属化浆料及其制备方法和应用。本发明的陶瓷金属化浆料，主要由以下质量分数的原料制成：3～30％金属超细粉，5～25％金属氧化物超细粉，15～30％有机溶剂，15～45％有机添加剂，余量为超细钯粉，其中，所述金属超细粉主要包括Ti超细粉、Pt超细粉、Zr超细粉或Ag超细粉中的任意一种或几种，所述金属氧化物超细粉主要包括YO超细粉、CaO超细粉、AlO超细粉、MgO超细粉、MnO超细粉或ZrO超细粉中的任意一种或几种。本发明的陶瓷金属化浆料，涂覆在陶瓷器件表面烧结形成的金属化层与陶瓷器件之间的附着力较大，且形成的金属化层不易开裂、起翘。
