The ceramic thick-film manufacturing for ceramic ink by an ink jet printing method

摘要

[PROBLEMS] The present invention discloses a ceramic ink having a filling rate of production is improved capable of ceramic thick film having a dense and improved ceramic properties. A ceramic ink according to the present invention comprises a predetermined solvent ceramic powder is dispersed, the particles of the ceramic powder has a maximum vertical length to maximum horizontal length D _h of the average, the particles cross D _v and the ratio of the difference value between the maximum horizontal length D _h in less than 20%, if there are multiple interior angles in the periphery of the cross section, maximum angle among the respective interior angle is less than 135 ° obtain. Further, the solvent is a mixture of ethylene glycol monomethyl ether and dipropylene glycol monomethyl ether, N, N-mixture of dimethylformamide and formamide, a mixture of acetonitrile and butanol, mixture of nitromethane and butanol, and water and N, N-dimethyl It may be at least one or more mixtures selected from the group consisting of formamide. .FIELD 9
