Abstract

Une composition de céramique diélectrique de solution solide comprend du manganotungstate de plomb [Pb(Mg1/2W1/2)O3], du nickeloniobate de plomb [Pb(Ni1/3Nb2/3)O3], du manganoniobate de plomb [Pb(Mg1/3Nb2/3)O3], du titanate de plomb [PbTiO3], ainsi que du zirconate de plomb [PbZrO3]. Ce matériau composite est exprimé par la formule [Pb(Mg1/2W1/2)O3]X - [Pb(Ni1/3Nb2/3)O3]Y - [Pb(Mg1/3Nb2/3)O3]Z - [PbTiO3]U - [PbZrO3]W, dans laquelle X + Y + Z + U + W = 1, et 0,05 « X « 0,3, 0,05 « Y « 0,5, 0,05 « Z « 0,75, 0,05 « U « 0,35, et 0,05 « W « 0,3. Ce matériau composite de céramique diélectrique présente d'excellentes caractéristiques comme matériau diélectrique pour un condensateur céramique monolithique.
