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.
Where is indium found in the world?
Specimens of uncombined indium metal have been found in a region of Russia and an indium mineral, indite, has been found in Siberia, but it is rare. World production comes mainly from Canada and is around 75 tonnes per year, reserves of the metal are estimated to exceed 1500 tonnes. Indium has no biological role.
How toxic is indium?
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 much indium is left in the world?
This makes it about three times more abundant than silver..." Another U.S. Geologic Survey report stated, "The world reserve base for indium is estimated to be about 5,700 t, which is far in excess of probable consumption over the next several decades...
What country produces the most indium?
China is the leading producer of indium; it accounts for a share of about 62% of the total global indium supplies. Indium obtained as a byproduct during the refining of zinc ore is minimal; therefore, its availability is limited.
History and Applications of Indium Metal
Is indium used in medicine?
An FDA-approved prescription drug, called indium (In-111) pentetreotide, is used by healthcare professionals to find certain tumors inside the body. It is given by IV.
How flammable is indium?
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.
What family is indium in?
The boron family contains elements in group 13 of the periodic talbe and include the semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
Who produces indium?
About half of global primary refined indium is produced in China. The remaining production is predominantly in Belgium, Canada, Japan, Peru, and South Korea.
Can indium be recycled?
As much as 86% of indium can be recycled via this environment-friendly, time-efficient method.
Is indium a liquid metal?
Eutectic gallium–indium alloy (EGaIn) liquid metal is highly conductive, moldable, and extremely deformable and has attracted significant attention for many applications, ranging from stretchable electronics to drug delivery.
What minerals contain indium?
Geologically, the occurrence of indium minerals is rare. The element most often occurs as a sulfide inclusion or substitutes in other base-metal minerals, including cassiterite, chalcopyrite, sphalerite and stannite.
Is lutetium a metal?
Lutetium (Lu), chemical element, a rare-earth metal of the lanthanide series of the periodic table, that is the densest and the highest-melting rare-earth element and the last member of the lanthanide series. In its pure form, lutetium metal is silvery white and stable in air.
Can we eat indium?
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.
What is Indium 111 used for in medicine?
Indium In 111 oxyquinoline labeled leukocytes may be used as an adjunct in the detection of inflammatory processes to which leukocytes migrate, such as those associated with abscesses or other infection, following reinjection and detection by appropriate imaging procedures.
Why is indium 111 used?
In can be used as a label for red cells, platelets, and leukocytes. It is prepared in a cyclotron by proton bombardment of a cadmium target. It has two major gamma-photon emissions—173 keV (90.5% yield) and 247 keV (94% yield)—which are excellent for counting in a gamma counter and for external imaging.
What is the use of bismuth?
Bismuth finds its main uses in pharmaceuticals, atomic fire alarms and sprinkler systems, solders and other alloys and pigments for cosmetics, glass and ceramics. It is also used as a catalyst in rubber production.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
How is indium purified?
The distribution ratios for the different metal ions show that indium(III) can be purified efficiently by a combination of extraction, scrubbing and stripping stages. This new ionic liquid process avoids the use of volatile organic solvents.
