nitrowe

Nitrowe is a term used in materials science to describe a family of nitrogen-rich ceramic materials that combine metal nitride layers with oxide-like blocks in a layered lattice.

The structure is typically described as a laminated or sandwich arrangement of MX-type nitride layers separated by oxide-like spacer blocks, yielding anisotropic mechanical and electronic properties. Reported properties include high hardness, thermal stability, and tunable electrical conductivity; some compositions show potential for ionic conduction at elevated temperatures.

Common synthesis routes involve high-temperature nitridation of metal precursors under nitrogen-containing atmospheres, followed by densification through spark plasma sintering or hot pressing. Thin-film variants can be deposited by chemical vapor deposition or atomic layer deposition, enabling layered architectures with controlled thickness.

Potential applications include protective coatings, cutting tools, catalysis, and energy storage electrodes for batteries and supercapacitors, as well as functional coatings in harsh environments.

Origin: The term nitrowe emerged in early 2000s speculative literature to describe a versatile class of layered nitride-oxide materials. It is not universally adopted, and researchers often prefer more specific subclass names based on the metal constituents.

Safety and handling: Handling requires standard ceramic powder safety protocols. Nitride materials can be reactive with moisture or acids, and powders pose inhalation risks; waste should follow institutional guidelines.
