Pellet vs. Sinter — What's the Difference?
By Fiza Rafique & Maham Liaqat — Updated on May 17, 2024
"Pellet" refers to small, rounded or cylindrical particles often used in various industrial processes, while "sinter" describes a mass of particles that have been fused together by heat without melting completely.

Key Differences
Pellet" typically refers to small, solid particles formed into a rounded or cylindrical shape. These are commonly used in industries such as agriculture, pharmaceuticals, and metallurgy. "Sinter" describes a solid mass created by heating powdered material just below its melting point until the particles adhere to each other. This process, known as sintering, is used in metallurgy, ceramics, and other fields to create strong, solid objects from powders.
Pellets are usually pre-formed and used as a raw material or product in various applications, whereas sintering is a process that transforms powdered materials into a coherent mass with enhanced properties.
Pellet production often involves extrusion or pelletizing processes, making it suitable for materials requiring consistent shape and size. In contrast, sintering involves thermal treatment, enhancing material properties such as strength, density, and structural integrity.
Pellets are primarily about shape and ease of use, while sintering is about changing material properties through heat.
