要約
(EN)
Disclosed is a method for producing a dielectric paste for multilayer ceramic electronic components which enables to produce a dielectric paste wherein a dielectric material is dispersed with high dispersibility while controlling the concentration of the dielectric material as desired. The method for producing a dielectric paste for multilayer ceramic electronic components is characterized by comprising a kneading step wherein a dielectric powder, a binder and a solvent are kneaded into a clayey mixture, and a slurrying step wherein the thus-obtained mixture is made into a slurry by adding the same solvent as used in the kneading step to the mixture and lowering the viscosity thereof.
(FR)
L'invention concerne une méthode pour produire une pâte diélectrique pour des composants électroniques multicouches en céramique. Cette méthode permet de produire une pâte diélectrique dans laquelle un matériau diélectrique est dispersé avec une grande dispersibilité, et de contrôler simultanément la concentration de ce matériau diélectrique pour obtenir une concentration voulue. La méthode permettant de produire une pâte diélectrique destinée à des composants électroniques multicouches en céramique est caractérisée en ce qu'elle comprend une étape de pétrissage dans laquelle une poudre diélectrique, un liant et un solvant sont pétris pour obtenir un mélange argilacé, et une étape de transformation en suspension épaisse dans laquelle un mélange ainsi obtenu se transforme en une suspension épaisse par l'ajout, au mélange, du même solvant que celui utilisé à l'étape de pétrissage, ce qui abaisse la viscosité du mélange.
