What element is found with gold?
An attractive and highly valued metal, gold has been known for at least 5500 years. Gold is sometimes found free in nature but it is usually found in conjunction with silver, quartz (SiO2), calcite (CaCO3), lead, tellurium, zinc or copper.
What are 3 uses for yttrium?
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.
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.
What kind of metal is yttrium?
metal
Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. Yttrium is a silvery white, moderately soft, ductile metal.

Where was yttrium found?
Though yttrium was discovered in Scandinavia, it is far more plentiful in other countries. China, Russia, India, Malaysia and Australia are the leading producers of yttrium.

How is yttrium used in phones?
Yttrium is widely used to produce phosphors that are used in cell phones and larger display screens as well as general lighting.
What are the most important facts about yttrium?
Basic Facts About Yttrium. Ytterby is the site of a quarry which yielded many minerals containing rare earths and other elements (erbium, terbium, and ytterbium). Isotopes: Natural yttrium is composed of yttrium-89 only. 19 unstable isotopes are also known. Properties: Yttrium has a metallic silver luster.
What can yttrium be used for in metal alloys?
Yttrium is also added to metal alloys to help improve resistance to corrosion and oxidation. “Like many elements, you won’t find yttrium as an element or compound in general use,” said Joseph Gambogi, mineral commodity specialist with the U.S. Geological Survey’s National Minerals Information Center.
Which is the only metal that is yellow or golden?
Gold Facts Gold is the only metal that is yellow or “golden.”. Other metals may develop a yellowish color, but only after they have oxidized or reacted with other chemicals. Nearly all of the gold on Earth came from meteorites that bombarded the planet over 200 million years after it formed. The element symbol for gold is Au.
What makes yttrium nitride a rare earth element?
Yttrium nitride (YN) is formed when the metal is heated to 1000 °C in nitrogen. The similarities of yttrium to the lanthanides are so strong that the element has historically been grouped with them as a rare-earth element, and is always found in nature together with them in rare-earth minerals.
