Diagram of a zinc-lead blast furnace system showing ore and coke entering through charge hoppers, with labeled furnace, air preheater, blower, taphole for slag and lead bullion, and a connected lead-splash condenser using rotors to separate and cool lead and zinc, with pathways for molten metals and off-gas. — metallurgy A zinc-lead blast furnace and lead-splash condenser. This technology is utilized mainly for producing zinc while managing both lead and zinc from raw materials, a technique that was highly influential in 20th-century smelting.

Metallurgy and materials science are closely related, but they differ in their scope and focus.

Metallurgy is the specialized art and science of extracting metals from their ores and modifying them for commercial use. It encompasses the study of the chemical, physical, and atomic properties of metals, as well as the principles used to create alloys. Traditionally, it focuses on the practical application of making useful metal products through processes like casting, forming, and heat treatment.12

Materials science is a broader, interdisciplinary field that emerged from an amalgam of metallurgy, solid-state physics, and chemistry. While metallurgy is restricted to metals, materials science investigates the properties of all solid materials—including polymers, ceramics, and composites—and how those properties are determined by their composition and structure.34

Over the 20th century, metallurgy evolved from a craft into a scientific discipline and eventually became a subset of the wider field of materials science. Today, the principles originally developed in physical metallurgy are applied across the entire spectrum of materials to design and select substances for diverse engineering applications.43
