Pore-filling slurry for high-temperature co-fired ceramic
The invention discloses a pore-filling slurry for high-temperature co-fired ceramics. The pore-filling slurry is composed of powder and an organic medium, the powder is composed of tungsten powder and inorganic phase powder, and the tungsten powder is composed of tungsten powder with different particle size ranges according to the following mass ratio: 0-10% of tungsten powder with particle size of 0.2-0.8 [mu]m; 70-90% of tungsten powder with a particle size of 1-2 [mu]m; and 0-20% of tungsten powder with a particle size of 2-5 [mu]m, wherein 0 is infinitely close to 0 but not 0, that is, the tungsten powder is formed by combining three kinds of tungsten powder with different particle sizes. The invention further provides a method for preparing the pore-filling slurry through premixing of the planetary ball mill and rolling of the three-roller grinder. The pore-filling slurry provided by the invention can be used for filling pores at one time under the low pressure of 120 N, small pores are full, the resistance value after sintering is within the range of 5-10 m omega/square, the air tightness is less than 10<-9> Pa.m<3>/S, the surface and the back face are flat, the height difference between a pore-filling part and ceramic is less than +/-15 [mu]m, and the pore-filling part is matched with the ceramic material strip, so that the problem that the shrinkage proportions of the pore-filling slurry and the ceramic material strip are inconsistent during ceramic-metal co-firing is solved.
本发明公开了一种用于高温共烧陶瓷的填孔浆料，由粉体和有机介质组成，粉体由钨粉和无机相粉体组成，所述钨粉为不同粒径范围的钨粉按下列质量配比组成：0.2‑0.8μm粒径钨粉：0％‑10％；1‑2μm粒径钨粉：70‑90％；2‑5μm粒径钨粉：0‑20％；其中的0代表无限接近于0但不为0，即钨粉由三种不同粒径的钨粉组合而成。本发明还提供行星球磨机预混三辊研磨机轧制制备填孔浆料的方法。本发明提供的填孔浆料可在120N的低压力下一次填孔，小孔饱满，烧结后方阻值在5‑10mΩ/□范围内，气密性＜10‑9Pa·m3/S。表面及背面平整，填孔处与陶瓷高度差小于±15μm，与陶瓷料带相匹配，解决了陶瓷金属共烧时填孔浆料与陶瓷料带收缩比例不一致的问题。
