Sintering

Part of speech: noun

Definitions

1. The technique consists of applying heat to fine particles, causing them to bond and create a solid mass, thus improving their durability and structural integrity
2. This method involves heating powdered materials until they coalesce into a unified, sturdy mass, enhancing their mechanical characteristics
3. This process entails the application of heat to powdered substances so that they fuse together, resulting in a coherent and resilient structure

Etymology: "Sinter" came into English from German "Sinter", a word for the crust or deposit left by water, and the same root produced the English "cinder". The two are doublets: they descend from one ancestor but reached English by different routes, so a term for the glowing residue of burnt coal and a term for mineral crust in a spring share a family tree. The German word originally named the hard deposit that forms as mineral-rich water dries or cools, which is why the material and the process of fusing it are linked in the same term. Sintering, the process named by the gerund of "sinter", takes that idea of hardened mineral deposit and applies it to powders. Heat is used to make fine particles fuse into a single solid mass without melting them fully, so the material becomes denser and stronger. The verb form carries the sense of this bonding process, and the noun for the whole technique follows from it.
