Liquid-phase sintering is a process used in materials science to create solid objects from powders. During this process, a small amount of liquid is formed from one of the components at high temperatures, which helps to bond the solid particles together. This liquid fills the spaces between the particles, allowing them to rearrange and densify, resulting in a stronger final product. This technique is commonly applied in the production of ceramics and metal alloys, enhancing their mechanical properties. The presence of the liquid phase reduces the temperature required for sintering, making it more energy-efficient and enabling the creation of complex shapes with improved performance characteristics.
