| 简介 |
A rare earth medium slurry for the rare earth thick-film circuit based on the metal substrate and producing process thereof, the slurry is composed of a solid phase component and an organic solvent carrier in wt ratio of (70-90) : (30-10). The solid phase component is SiO2-Al2O3-CaO-B2O3-La2O3-based microcrystal glass in wt ratio of SiO2 : 30%-65%, Al2O3 : 5%-26%, CaO : 18%-38%, B2O3 : 2%-16%, La2O3 : 0. 3%-15%, Co2O3 : 0. 05%-6%, TiO2 : 1%-10%, ZrO2 : 1-10%. Its producing process includes following steps : (1) preparing the rare earth microcrystal glass powder; (2) preparing the organic solvent carrier; (3) roller trio mixing and roller trio rolling; (4) preparing the rare earth slurry. The slurry is in use of ferrite-based stainless steel substrate. |
