Amalgam is a type of alloy composed of two or more metals, often involving mercury. Chemically, the process of amalgamation involves mercury liquid reacting with solid metallic components to form a homogeneous alloy. The composition and resulting physical properties of the amalgam are highly dependent on the specific metals utilized and their precise ratios. Amalgams are generally solid-state mixtures that exhibit unique metallurgical characteristics stemming from the liquid metal binding the solid elements together.
