Indium (In)

Indium is a soft, malleable post-transition metal used extensively in touchscreens (Indium Tin Oxide).

Core Principles & Analysis

• Ferdinand Reich and Hieronymus Theodor Richter discovered indium spectroscopically in 1863, naming it for its indigo-blue emission line.
• The soft metal emits a high-pitched 'cry' when bent and wets glass, letting it form strong seals.
• Indium tin oxide provides the transparent conductive coating on virtually every touchscreen and liquid-crystal display.
