HISTORY OF INDIUM Ferdinand Reich and

Hieronymus Theodor Richter (1863)

Indigo blue line found in zinc ore spectrum

Indium named after indigo

PROPERTIES OF INDIUM Atomic #: 49 Atomic Weight: 114.818 Melting Point: 156.60 degrees Celsius Boiling Point: 2072 degrees Celsius Density: 7.31 grams/cm3

MORE PROPERTIES! Phase at Room Temperature: Solid Element Classification: Metal Period #: 5 Group #: 13 Softer than lead Remains soft and easy to work with at

very low temperaturesTemperatures near absolute zero (-273

degrees Celsius)

INDIUM’S NATURAL CREATION Goes through S-process in low mass

starsSlow-neutron-capture process

Takes THOUSANDS of years! Cadmium needed to capture neutrons Undergo Beta decay

WHERE IS INDIUM FOUND? Earth’s crust Slightly more abundant than silver Relatively rare Zinc ores

HAZARDS! Exposure through: inhalation, ingestion,

skin or eye contact Very poisonous when injected into skin Irritation of eyes, skin and respiratory

system Possible liver, kidney, heart, blood

defects Pulmonary edema (fluid build up in lung

air sacks)

WHAT IS INDIUM USED FOR? Primary use: Making Alloys

Sometimes added to gold and platinum to make them harder

Used in electronic devices and dental materials

Used with germanium to make transistors (found in computers in cell phones)

WHAT IS INDIUM USED FOR? Coats bearings in aircraft engines Makes thin films for LCD displays Indium Gallium Arsenide (solar cells) Mirrors
