Ceramic Powders for Advanced Ceramics: What are Ideal Ceramic Powders for Advanced Ceramics?

Transactions of the Materials Research Society of Japan, 2010
One of the most important factors for advanced ceramic preparation is the nature of powders. This article is a review and overview of powder preparation and properties and explains ideal powders for advanced ceramics. In addition, hydrothermal powders that are close to ideal powders are described along with hydrothermal processing.

Li2CO3-affiliative mechanism for air-accessible interface engineering of garnet electrolyte via facile liquid metal painting

Nature Communications, 2020
At Li-garnet interface, the poor interfacial wettability due to Li2CO3 passivation causes large resistance and unstable contact. Here the authors propose a Li2CO3-affiliative mechanism for air-accessible interface engineering of garnet electrolyte with ...
