METHOD FOR PRODUCING HIGHLY DIELECTRIC ELASTOMER COMPOSITION AND HIGHLY DIELECTRIC ELASTOMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a highly dielectric elastomer composition compounded with highly dielectric ceramic powder containing Li as a constituting element and obtained by a combustion synthesis method at a low cost, by which the specific dielectric constant of the composition can be improved.;SOLUTION: This method for producing the highly dielectric elastomer composition comprising an elastomer and a highly dielectric ceramic powder containing Li as a constituting element is characterized by comprising a mixing process for mixing reaction raw materials containing at least a metal powder as a heat-generating source, a substance used as an oxygen-supplying source, and a Li-containing substance in a prescribed ratio, respectively, a reaction process for reacting the mixture mixed in the prescribed ratio, a calcination process for calcining the reaction product obtained in the reaction process, a dry-crushing process for dry-crushing the calcined reaction product to obtain the highly dielectric ceramic powder, and a process for compounding the highly dielectric ceramic powder with the elastomer.;COPYRIGHT: (C)2009,JPO&INPIT
