Cold sintering of materials includes using a process of combining at least one inorganic compound, e.g., ceramic, in particle form with a solvent that can partially solubilize the inorganic compound to form a mixture; and applying pressure and a low temperature to the mixture to evaporate the solvent and densify the at least one inorganic compound to form sintered materials.

Cold sintering composites and ceramics

Dielectric compositions that include compound of the formula [(M')(A&#x2032;)][(M&#x2033;),(B&#x2033;)(C&#x2033;)]O(V)and protonated dielectric compositions that include a protonated dielectric compound within the formula [(M&#x2032;)(A&#x2032;)](M&#x2033;)(B&#x2033;)(C&#x2033;)]O(V)(H)are disclosed. Composite materials that employ one or more of these dielectric compounds together with an electrolyte also are disclosed. Composite material that employs one or more of these dielectric compounds together with an electrochemally active material also are disclosed.

High energy density ionic dielectric materials and devices

Co-fired multilayer piezoelectric ceramic materials with base metal electrodes based on copper, copper alloy, are found as an effective approach to manufacture low cost multilayer piezoelectrics. The method of the invention is performed at low firing temperature and without the oxidation of base metal or reduction of ceramic components. A variety of ceramic materials may be used and copper is the preferred base metal in the multi-layer piezoelectric devices of the invention. This copper has additional protection against oxidation with a small inorganic coating on the surface. With such protection, the binder and other organics can also be efficiently removed and produce superior performance in the piezoelectric structured devices.

Method of preparing multilayered piezoelectric ceramic material

An IPD has a varistor of electrodes and a ZnO dielectric. A capacitor includes electrodes and a dielectric that has oxides of bismuth, magnesium, and niobium having a pyrochlore structure of type A B O . The materials are applied as wet layers and are sintered for integrated production.
