MICROWAVE DIELECTRIC CERAMICS

摘要

The ceramic composition comprises barium oxide, cerium oxide, lantan oxide and titanium dioxide having the following equations; x(Ba1-alpha= Pbalpha)O-y(ND2O3(1-beta.r)= CeO2(beta)= The ceramic composition comprises barim oxide, lead oxide, niodium La2O3r)-zTiO2(where, 6 < x 20, 10 < y < 20, 60< z < 75, 0 < alpha < 0.5, 0 < beta < 0.2, 0 < r < 0.2, 0 < 1-beta-r < 1, x+y+z= 100). In the electric ceramic composition, barium carbonate can use instead of the barium oxide, lead trioxide can also use instead of lead oxide.
