In chemistry, a Zintl phase is a product of a reaction between a group 1 or group 2 and main group metal or metalloid. It is characterized by intermediate metallic/ionic bonding. Zintl phases are a subgroup of brittle, high-melting intermetallic compounds that are diamagnetic or exhibit temperature-independent paramagnetism and are poor conductors or semiconductors.

John Dudley Corbett was an American chemist who specialized in inorganic solid-state chemistry. At Iowa State and Ames Lab, Corbett lead a research group that focused on the synthesis and characterization of two broad classes of materials, notably Zintl phases and condensed transition metal halide clusters. Both classes of materials are important for their uses, for instance thermoelectrics, and for the theoretical advances they made possible by working to understand their complex bonding and electronic properties.
The dividing line between metals and nonmetals can be found, in varying configurations, on some representations of the periodic table of the elements. Elements to the lower left of the line generally display increasing metallic behaviour; elements to the upper right display increasing nonmetallic behaviour. When presented as a regular stair-step, elements with the highest critical temperature for their groups lie just below the line.

Wilhelm Karl Klemm was an inorganic and physical chemist. Klemm did extensive work on intermetallic compounds, rare earth metals, transition elements and compounds involving oxygen and fluorine. He and Heinrich Bommer were the first to isolate elemental erbium (1934) and ytterbium (1936). Klemm refined Eduard Zintl's ideas about the structure of intermetallic compounds and their connections to develop the Zintl-Klemm concept.
