What are 5 uses for indium?
Indium is used to dope germanium to make transistors. It is also used to make other electrical components such as rectifiers, thermistors and photoconductors. Indium can be used to make mirrors that are as reflective as silver mirrors but do not tarnish as quickly. Indium is also used to make low melting alloys.
What is an interesting fact about indium?
Indium is rarely found uncombined in nature and is typically found in zinc, iron, lead and copper ores. It is the 61st most common element in the Earth’s crust and around three times more abundant than silver or mercury, according to the U.S. Geological Survey (USGS).

| Molar magnetic susceptibility | −64.0×10−6 cm3/mol (298 K) |
| Young’s modulus | 11 GPa |
| Mohs hardness | 1.2 |
| Brinell hardness | 8.8–10.0 MPa |
What color is indium?
silvery white
Indium is a soft, ductile, manleable, lustrous metallic metal. Its colour is silvery white and it has a face-centered tetragonal structure. It is liquid over a wide range of temperatures, like gallium that belongs to its same group.
Where is indium mined?
About half of global primary refined indium is produced in China. The remaining production is predominantly in Belgium, Canada, Japan, Peru, and South Korea.
What type of metal is indium?
indium (In), chemical element, rare metal of main Group 13 (IIIa, or boron group) of the periodic table. Indium has a brilliant silvery-white lustre. It was discovered (1863) by German chemists Ferdinand Reich and Hieronymus Theodor Richter while they were examining zinc ore samples.
Is indium a rare earth?
The modern world needs rare earth elements. The trace minerals that perform the roles that other raw materials cannot.
Is indium flammable?
FIRE HAZARDS * Indium Metal does not burn. * POISONOUS GASES ARE PRODUCED IN FIRE. * Use a dry chemical extinguisher. * Indium powder or dust is flammable and may ignite when exposed to heat or flame.
