<p>PURPOSE:To make it possible to absorb noise laving low voltage and noise of high frequency by making Sr(1-x)BaxTiO3 contain at least one kind or more among Nb2O5, Ta2O5, etc., and Mn, Si, Na2 SiO3, and Al2O3. CONSTITUTION:Sr(1-x)BaxTiO3 (where 0<X<=0.3), which contains excessive Ti so that the mol ratio between Sr(1-x)Bax and Ti may be 0.95<=Sr(1-x)Bax/Ti<1.00, is made to contain at least one kind or more among Nb2O5, Ta2O5, V2O5, W2O5, Dy2O3, Nd2O3, Y2O3, La2O3, and CeO2 by 0.05-2.0mol%, Mn and Si by 0.2-5.0mol% in total amounts, respectively, in terms of MnO5 and SiO2, and Na2SiO3 by 0.05-2.0mol%, and Al2O3 by 0.05-2.0mol%. Hereby, noise of low voltage end noise of high frequency can be absorbed.</p> |
