The k of ceramic materials is the ratio of its permittivity (ε0) to the permittivity in a vacuum (ε0) (43). The dielectric constant of ceramic materials can be measured by the ratio of the capacitance of a ceramic capacitor (Cc) and the capacitance of a similar capacitor in vacuum (...
Ceramic dielectric matl. with low temp.-dependence of the dielectric constants, based on barium titanate contg. iron and/or zinc, the novelty being that the matl. also contains aluminium. The amt. of Al, by wt. is pref. 2-27% esp. 4-5% with 0.05-0.5% Fe, or 0.6-1.2% Zn, opt....

Macor ceramics have a dielectric constant that is higher than other ceramics. Corning Inc. has developed a ceramic that is easy to work with, Macor microcrystalline. This ceramic is biocompatible and has a low dielectric coefficient. It is used in many industries, such as aerospace, medical and...
Two mechanisms which may account for the effect, inertial clamping of the piezoelectric response of ferroelectric domains and clamping of domain‐wall motion, are discussed.关键词: Ceramics Titanates Dielectric constant Dielectrics Frequency measurement ...
The role ofdielectric constantε of a solvent regarding its capability to dissolve ionized solutes was pointed out in Section4.1(thedielectric constant is typically given as the relative dielectric constant to vacuum). Ahigher dielectric constantof the solvent correlates with a higher ability of the ...
