Dispersible dielectric particles and methods of forming the same

摘要: Methods of forming dispersible dielectric particles, as well articles and compositions that include the are provided. The methods involve an aqueous mixture (e.g., barium titanate-based) particles replacing at least a portion water in with non-aqueous solvent ethanol). According to one set methods, then dried. limited, or lack, present during drying reduces capillary forces otherwise may draw together cause formation strong agglomerates. Thus, particle agglomeration be reduced which increases dispersibility. another invention, not dried after replacement, thus, avoiding agglomerates increasing In both sets (or mixtures thereof) further processed, for example, form composite layers. As result increased dispersibility, relatively uniformly distributed throughout polymeric material. This uniform distribution improves properties layers used embedded capacitor electronic applications including printed circuit boards.
