Ceramic compositions having high dielectric constant |
| 摘要 |
A ceramic composition allowing low-temperature sintering at a temperature below 1000 DEG C and having a high dielectric constant over 5000 essentially contains Pb(Fe 2/3 W 1/3)O3 and Pb(Fe 1/3 Nb 2/3)O3, in which the molecular ratio of Pb(Fe 2/3 W 1/3)O3 to Pb(Fe 1/3 Nb 2/3)O3 ranges from about 0.2 to 0.5.
