Is indium toxic to humans?
Indium is relatively non-toxic and poses little immediate hazard to the health of emergency response personnel or the environment in an emergency situation. Potential Health Effects: Relatively non-toxic to humans by inhalation or ingestion.
How conductive is indium?
Indium metal has a high thermal conductivity (86W/m-k) but silver, gold, and even aluminum, have higher thermal conductivity.
What are the properties of indium?
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. Both indium and gallium are able to wet glass.
Can you chew indium like gum?
Makes for a great little desk toy if you out it in a small jar. They cold weld very easily, and, fun fact, it is the only element in the universe that you can chew like bubblegum, as it is soft and non-toxic!
Is indium a rare earth metal?
Due to the high demand, most of the indium has been processed into indium tin oxide since 1992. Indium is a rare element, its share in the continental crust is only 0,05 ppm. It is thus of a similar frequency as silver and mercury.
Is indium an insulator?
There is no scientific cutoff for “good” or “bad” conductors, though the conductivity of indium is high enough that it is considered a conductor rather than a semiconductor or an insulator.
What is indium foil?
Indium foil is widely used in nuclear facilities to capture thermal neutrons, because it shows a high cross section of neutron capture reaction. Hence, it may be used in dosemeters to measure exposure. Indium foils were studied for simultaneous monitoring neutron and photon intensities in a reactor core.
Is indium paramagnetic or diamagnetic?
Magnetic Type of the elements
| Hydrogen | Diamagnetic | Niobium |
|---|---|---|
| Fluorine | N/A | Indium |
| Neon | Diamagnetic | Tin |
| Sodium | Paramagnetic | Antimony |
| Magnesium | Paramagnetic | Tellurium |
What is indium on the periodic table?
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 the softest metal?
Indium is the softest metal that is not an alkali metal. It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. Indium has a melting point higher than sodium and gallium, but lower than lithium and tin.
Is indium radioactive?
Two naturally occurring isotopes of indium exist, indium-113 and indium-115. Indium-115 is radioactive. A radioactive isotope is one that breaks apart and gives off some form of radiation. Indium-115 has a half life of about 440 trillion years.
What are the macroscopic magnetic properties of indium?
The macroscopic magnetic properties of a material are a consequence of interactions between an external magnetic field and the magnetic dipole moments of the constituent atoms. Different materials react to the application of magnetic field differently. Electrical resistivity of Indium is 83.7 nΩ⋅m.
What are the properties of the element indium?
Summary Element Indium Vickers Hardness N/A Melting Point 156.6 °C Boiling Point 2072 °C Thermal Conductivity 82 W/mK
Why does indium make a high pitched sound when bent?
Indium has a low melting point for metals and above its melting point it ignites burning with a violet flame. Bizarrely, the pure metal of indium is described as giving a high-pitched “cry” when bent. This is similar to the sound made by tin or the ‘tin cry”, however, neither of them is really much like a cry!
Which is higher in melting point indium or gallium?
It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. Indium has a melting point higher than sodium and gallium, but lower than lithium and tin.
