Title:
FILTRATION MATERIAL AND METHOD FOR PRODUCING MULTILAYER CERAMIC CAPACITOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/057849
Kind Code:
A1
Abstract:
The present invention provides a filtration material which is capable of removing fine inorganic particles from an inorganic paste such as a ceramic slurry and an conductive paste, the inorganic paste being used during the production of a multilayer ceramic capacitor. The present invention provides a filtration material for filtering an inorganic paste which contains first inorganic particles having a particle diameter of 20 nm to 300 nm, second inorganic particles having a particle diameter of less than 20 nm, an organic solvent, a binder and a dispersant; and a potential having a polarity reverse from the polarity of the first inorganic particles and the second inorganic particles is applied to this filtration material.
