What are yttrium physical properties?
Physical properties Yttrium has a bright, silvery surface, like most other metals. It is also prepared as a dark gray to black powder with little shine. Yttrium has a melting point of 1,509°C (2,748°F) and a boiling point of about 3,000°C (5,400 F). Its density is 4.47 grams per cubic centimeter.

What is yttrium oxide used for?
Yttrium oxide (Y2O3) nanoparticle is an air-stable, solid substance white in color. It is used in the field of material sciences, to make phosphors that are used in imparting the red color of the picture tubes in televisions. Another major use of the yttrium oxide nanoparticles is in inorganic synthesis.
What is a chemical property of 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.
What is an interesting fact about 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.
What type of bond is yttrium oxide?
Explanation: Yttrium is a metal and oxygen a non-metal – because non-metals tend to gain and metals tend to lose electrons, metals typically react with non-metals by transferring electrons between them and forming ionic compounds (‘salts’). Yttrium has the electronic configuration Kr 5s2 4d1.
What is yttrium fluoride used for?
Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics.
Is yttrium oxide ionic?
Yttrium has the electronic configuration Kr 5s2 4d1. This means that it tends to react by losing 3 electrons and forming a 3+ ion. Therefore, 2 yttrium atoms transfer 6 electrons to 3 oxygen atoms, making two yttrium 3+ ions and three oxide (2-) ions and thus the formula of yttrium oxide is Y2O3 .
What are some fun facts about yttrium?
Interesting Yttrium Facts: This mineral was found in Ytterby, Sweden, giving it its name. In 1828, Friedrich Wohler extracted an impure sample of yttrium by reducing anhydrous chloride and potassium. Yttrium is a transition metal that is often called a rare earth element.
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.
How 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.
What is the chemical name of yttrium oxide?
From Wikipedia, the free encyclopedia Yttrium oxide, also known as yttria, is Y 2 O 3. It is an air-stable, white solid substance. The thermal conductivity of yttrium oxide is 27 W/ (m·K).
What is yttrium used for in everyday life?
Yttrium Chemical & Physical Properties. The oxides have potential use in ceramics and glass. Yttrium oxides have high melting points and impart shock resistance and low expansion to glass. Yttrium iron garnets are used to filter microwaves and as transmitters and transducers of acoustic energy.
How do you make yttrium oxide?
Y 2 O 3, the normal oxide of the element yttrium, closely resembles the lanthanide oxides in most of its properties. It is produced industrially by solvent extraction from ores that also contain the heavier lanthanides. The major commercial source is the mineral xenotime.
What are the properties and isotopes of yttrium?
Isotopes: Natural yttrium is composed of yttrium-89 only. 19 unstable isotopes are also known. Properties: Yttrium has a metallic silver luster. It is relatively stable in the air except when finely divided. Yttrium turnings will ignite in air if their temperature exceeds 400°C.
