Gallium

20 January 2016

Nicknamed the “Terminator Metal” for its liquid metal appearance at room temperature, Gallium is a chemical element with symbol Ga and atomic number 31. It is a soft, silvery metal that melts at 30°C and is predominantly used in electronics and semiconductors.

Here gallium is being oxidized by a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2). As the metal is heated it forms ornate patterns as the oxidation reaction proceeds across the surface.
