## Definition

a solid material made of carbon and nitrogen that is created when certain chemicals are heated. It is usually a yellow or orange powder used in science experiments.

For teachers: a polymeric carbon nitride compound, typically appearing as a yellow solid, formed by the thermal decomposition of nitrogen-rich precursors like melamine or melem.

## Examples

- The scientist synthesized mellon in the laboratory.
- Researchers are studying mellon as a potential photocatalyst because it is stable and reacts well with light.
- The structural complexity of mellon, characterized by its linked heptazine units, makes it a significant subject of study in the development of advanced carbon nitride materials.

## Usage notes

- Used primarily in the context of polymer chemistry and materials science.
