CERAMICS-CONTAINING DISPERSANT, A METHOD FOR PRODUCING SAME AND THE USE OF SAID DISPERSANT IN THICK-FILM PASTES

摘要

Disclosed is a ceramics-containing dispersant comprising a ceramic component, a solvent and a dispersion medium. The ceramic component is provided at least essentially in the form of primary particles having an average particle size of 5 nm to 50 nm. The ceramic component in the material is also provided with a specific surface of 20 m<2>/g to 120 m<2>/g. The invention also relates to a method for producing said dispersant. The original ceramic component, together with the dispersion medium and the solvent, is subjected to a treatment step by means of which the average particle size of the original ceramic powder is reduced in such a way that the ceramics-containing dispersant is obtained. The inventive dispersant, together with an added binder and a softener, is particularly suitable for being used in thick-film pastes, such as those used in serigraphy methods or in the production of ceramics that are fired according to the post-firing method.
