Dieletric ceramic composition and ceramic electronic element using the same |
摘要 |
<p>A dielectric ceramic composition which has a high dielectric constant and a high Q value, as well as excellent temperature stability, and which is sinterable at a relatively low temperature. The dielectric ceramic composition of the present invention is formed of a mixture of a BaO-TiO2-REO3/2-BiO3 ceramic composition wherein RE represents a rare earth element, and a glass composition. The glass composition contains 13-50 wt.% SiO2, 3-30 wt.% B2O3, 40-80 wt.% alkaline earth metal oxide, and 0.1-10 wt.% Li2O.</p> |
