Is indium toxic to humans?
Indium is considered a technology-critical element. Indium has no biological role. Its compounds are toxic when injected into the bloodstream. Most occupational exposure is through ingestion, from which indium compounds are not absorbed well, and inhalation, from which they are moderately absorbed.
What element can you chew?
I show off my sample of Indium by taking a bite out of it.
Can you touch indium?
Indium forms an alloy with gallium that is liquid at room temperature, and is fairly non-toxic. This would be a great substitute for mercury, except it sticks to everything and stains hands, which means you can't really touch it either.
What does indium feel like?
Indium is a lustrous silvery metal that is so soft and malleable it can be scratched with a fingernail and bent into nearly any shape. In nature, indium is quite rare and nearly always found as a trace element in other minerals — particularly in zinc and lead — from which it is typically obtained as a byproduct.
How much is indium worth?
Ingot prices set by metals companies for 99.99% pure indium range from $470 USD per kilogram to $490 USD for a kilogram of 99.999% purity.
Is indium a precious metal?
The most precious metals are rhodium, platinum, gold, ruthenium, iridium, osmium, palladium, rhenium, silver, and indium.
Can you eat indium metal?
When taken by mouth: Indium is POSSIBLY UNSAFE when taken by mouth. Indium is thought to be toxic to many parts of the body.
What is the softest metal on the earth?
Caesium* Caesium is the softest metal with the Mohs hardness of 0.2.
Is indium used in iphones?
It also uses a graphite anode and aluminum casing. Electronics: Processor Chip: The phone's processor is mainly made from silicon, but it is bombarded by various elements such as phosphorus, antimony, arsenic, boron, indium, and gallium to give it superior electrical properties.
What do you use indium for?
Most indium is used to make indium tin oxide (ITO), which is an important part of touch screens, flatscreen TVs and solar panels. This is because it conducts electricity, bonds strongly to glass and is transparent. Indium nitride, phosphide and antimonide are semiconductors used in transistors and microchips.
How much indium is left in the world?
According to a U.S. Geologic Survey (USGS) report indium is abundant "in the Earth's crust at an estimated 240 parts per billion by weight. This makes it about three times more abundant than silver..."
Is indium a radioactive element?
Indium (49In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115In) being measurably though weakly radioactive. Its spin-forbidden decay has a half life of 4.41×1014 years.
How is indium used in phones?
Indium is used in many high-tech devices such as touch screens, smart phones, solar panels and smart windows, in the form of indium tin oxide. This compound is optically transparent and electrically conductive — the two crucial features required for touch screens to work.
What can replace indium?
In AltiTude m-TCOs, the indium is replaced with lower cost and more readily available metals such as Galium, Zinc and Tin. The result would be an enormous reduction in industry costs and a great increase in sustainability for electronics, displays and solar industries.
Where is indium found?
What is Indium? Indium is a silvery-white metal named for its indigo blue line in the atomic spectrum. Relatively scarce on the Earth's crust, indium is found with zinc sulfide ores, as well as iron, lead and copper ores.
Why does metal work on my touch screen?
Aluminum. In addition to copper, aluminum is another material that works with capacitive touchscreens. While aluminum isn't as conductive as copper, it's still able to conduct electricity — just like your bare fingers. As a result, it's supported by capacitive touchscreens.
