Most of the dielectric ceramic compositions consist of three or more different lead-based or non-lead ceramics. These materials and their solid solutions can give high dielectric constants (er>10000) but the disadvantage is large fluctuations in the dielectric constant with increasing or decreasing .....

This invention presents a multi-stage chemical vapor deposition method for producing a stable diamond film electrode coated on titanium substrate. The substrate temperature is programmed at different deposition stages. With this process, a high-quality multi layer structure is produced as the interl.....
