sintering

Sintering is a process where powdered materials are heated to a temperature below their melting point, causing the particles to fuse together into a solid, cohesive piece. The heat allows atoms at the surfaces of particles to bond, gradually reducing porosity and increasing strength. This method is commonly used in manufacturing ceramics, metals, and composites to create strong, dense objects with precise shapes, often after shaping the powder into a desired form. Sintering improves the material's properties while avoiding melting, making it energy-efficient and suitable for complex or delicate shapes.
