Is indium poisonous?
Indium is a moderately toxic metal by inhalation and mildly toxic by ingestion. However, the exact nature of its human toxicity is not clearly understood. Indium is a soft, malleable metal with a brilliant lustre. Indeed, when pure, it sticks very tightly to itself or to other metals.
Is indium flammable?
INDIUM is a non-combustible solid in bulk form but is flammable in the form of a dust. Reacts with strong oxidizing agents. Reacts explosively with dinitrogen tetraoxide dissolved in acetonitrile. Reacts violently with mercury(II)bromide at 350°C.
Is indium named after India?
They named the element indium, from the indigo color seen in its spectrum, after the Latin indicum, meaning ‘of India’.

Why is indium expensive?
Indium is produced as a byproduct primarily from zinc mining. China has 60-70% of the world’s indium smelting capacity. Indium’s price fluctuates wildly and currently the metal trades for $580 per kilogram. One of the world’s largest unexploited resources of indium is the Malku Khota deposit in Bolivia.
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.

Why are rare earths called rare?
They are known as “rare” because it is very unusual to find them in a pure form, but it turns out there are deposits of some of them all over the world – cerium, for example, is the 25th most common element on the planet. The term “earth” is simply an archaic term for something you can dissolve in acid.
Why are pure elements so rare?
Although originally thought to be rare, many of the minerals are actually common in the Earth’s crust. However, due to the difficulties in extracting the metal from the ore, rare is a fitting term. These elements rarely exist in pure form; they are usually found within other minerals, making them costly to mine.
Is Lithium a rare earth metal?
Although lithium is widely distributed on Earth, it does not naturally occur in elemental form due to its high reactivity. According to the Handbook of Lithium and Natural Calcium, “Lithium is a comparatively rare element, although it is found in many rocks and some brines, but always in very low concentrations.
Where do rare earths come from?
Rare-earth ore deposits are found all over the world. The major ores are in China, the United States, Australia, and Russia, while other viable ore bodies are found in Canada, India, South Africa, and southeast Asia.
Will we run out of rare earth metals?
The reserves of some rare earth minerals used in electronics, medical equipment and renewable energy could run out in less than 100 years. Rare earth minerals are naturally occurring resources, which cannot be recreated or replaced. Some minerals are only present in very tiny quantities.
Does the US have rare earth deposits?
In its 2020 annual report, the government agency said although some 20 countries worldwide are currently mining rare earths, the U.S., with its 1.4 million-ton reserve, remains home to one of the largest rare earth deposits in the world.
What rare earth metals are used in cell phones?
Scandium and yttrium are included in the rare-earth metals because their chemical properties are similar to those of the lanthanides. A single iPhone contains eight different rare-earth metals.
