Yttrium is widely used to produce phosphors that are used in cell phones and larger display screens as well as general lighting. Yttrium in red phosphors in color television tubes led to widespread use in the 1960s and ’70s. Fluorescent tubes (linear and compact) use significantly more yttrium per watt than LED bulbs.Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation. Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals.Yttrium oxide is added to the glass used to make camera lenses to make them heat and shock resistant.

What is ytterbium used for?
Uses of Ytterbium
It is used as a doping agent to improve the strength, grain refinement and mechanical properties of stainless steel. It also acts as an industrial catalyst. Few alloys of Ytterbium are used in dentistry.
How is yttrium used in microwaves?
If you use a microwave to heat food, you’re using yttrium! Garnets, which are a type of gemstone, can be created by combining yttrium and iron.
Is yttrium safe to touch?
Avoid contact with skin and eyes. Eliminate all sources of ignition. Methods and Materials for Containment and Cleaning Up: Avoid dust formation. Sweep or scoop spilled product and place in a closed container for further handling and disposal.
Is yttrium used in lightbulbs?
In low-energy bulbs an electric discharge passes through argon gas containing mercury, which generates UV light. This in turn activates the coating on the inside surface of the bulb, which shines brightly. The coating includes five rare elements: cerium, europium, lanthanum, terbium and yttrium.

How is yttrium used in LED lights?
The way it is used in white LEDs is interesting, as Cesium doped Yttrium Aluminium Garnet (YAG, Y3Al5O12) – it is a phosphor that emits a yellow light. As a coating in high brightness blue InGaN diodes this converts some of the blue light to yellow – giving an overall white light.
Is yttrium toxic to humans?
Water soluble compounds of yttrium are considered mildly toxic, while its insoluble compounds are non-toxic. In experiments on animals, yttrium and its compounds caused lung and liver damage.
How is yttrium used in everyday life?
Yttrium can be used as an additive to strengthen metals, like aluminum and magnesium alloys. It’s also used to help make microwave filters, high-temperature superconductors, oxygen sensors, white LED lights, and metal-cutting lasers. When added to camera lenses, the camera lenses become heat and shock resistant.
What does yttrium smell like?
If you were to smell yttrium, you wouldn’t smell anything! It’s odorless. Other properties of yttrium include: A melting point of 1522 degrees C, or 2772 degrees F, or 1795 K.

How much does yttrium cost?
Yttrium is currently worth $3,400 per pound, europium costs $20,000 per 100 grams and terbium sells for $1,800 per 100 grams. Dysprosium, the cheapest of the rare-earth elements discovered, only costs $450 per 100 grams.
What is ytterbium found in?
What color does ytterbium burn?
Ytterbium burns with a characteristic green flame, notably in compositions with hexachloroethane and polytetrafluoroethylene. Ytterbium reacts vigorously with dilute acids to form salts. Most of these salts are soluble in water except for the fluoride, sulfate, and oxalate. All of these salts are white in color.
What does ytterbium look like?
Ytterbium is a bright, soft, silvery-white metal that is both ductile and malleable. It is a one of the rare earth metals. The metal tarnishes quickly in air and reacts slowly with water. It dissolves rapidly in mineral acids.
What color is yttrium?
Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3.
Can yttrium be recycled?
In economic terms, it is profitable to recycle yttrium if its market price is above 14€/kg, and above 9.54€/kg taking in consideration the external costs of mining. Therefore, in 2012 and 2013, recycling was profitable thanks to the high price of yttrium, while between 2014 and 2016 recycling was not cost effective.
What is the flammability of yttrium?
FIRE HAZARDS
* Yttrium is a noncombustible solid, however, it is FLAMMABLE when in powdered or finely divided form. * Use a dry chemical extinguisher. * POISONOUS GASES ARE PRODUCED IN FIRE, including Yttrium Oxide fumes.
Where can I find yttrium?
Yttrium can be found in most of the rare earth minerals, but has never been discovered in the Earth’s crust as a freestanding element. Lunar rocks gathered during the Apollo moon missions contain yttrium. The human body also contains yttrium in tiny amounts, usually concentrated in the liver, kidneys, and bones.
Does yttrium react with water?
Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. It reacts with water decomposing it to release hydrogen gas, and it reacts with mineral acids.

Is yttrium a rare-earth element?
The non-lanthanide rare-earth elements, yttrium and scandium, are 29th and 44th, respectively, in their abundances. Lanthanum and the light lanthanides (cerium through europium) are more abundant than the heavy lanthanides (gadolinium through lutetium).
What element has the atomic number 57?
