    • The present invention discloses a ceramic ink having an improved refill rate, which enables the manufacture of a ceramic thick film having delicate and improved ceramic properties. To this end, the ceramic ink of the present invention contains a certain amount of a solvent in which ceramic powder is dispersed, and the particles of the ceramic powder have on average a ratio of less than 20% in difference value between the maximum vertical length Dv and the maximum horizontal length Dh with respect to the maximum horizontal length Dh of the cross section of the particle. Also, in case of the presence of a plurality of interior angles at the circumference of the cross section, the maximal angle can be less than 135° among the interior angles. In addition, the solvent can be one or more mixtures selected from the group consisting of a mixture of ethylene glycol monomethyl ether and dipropylene glycol monomethyl ether, a mixture of NN-dimethylformamide and formamide, a mixture of acetonitrile and butanol, a mixture of nitromethane and butanol, and a mixture of water and N,N-dimethylformamide.
    • 本发明公开了一种具有改进的再填充率的陶瓷油墨,其能够制造具有精细和改善的陶瓷性能的陶瓷厚膜。 为此,本发明的陶瓷油墨含有一定量的分散有陶瓷粉末的溶剂,陶瓷粉末的粒子的平均比例小于20%,最大垂直长度 Dv和最大水平长度Dh相对于颗粒截面的最大水平长度Dh。 此外,在横截面的圆周处存在多个内角的情况下,最大角度可以在内角之中小于135°。 此外,溶剂可以是一种或多种选自乙二醇单甲醚和二丙二醇单甲醚的混合物,硝基二甲基甲酰胺和甲酰胺的混合物,乙腈和丁醇的混合物,硝基甲烷的混合物 和丁醇,以及水和N,N-二甲基甲酰胺的混合物。
