A rare-earth element (REE) or rare-earth metal (REM), as defined by the International Union of Pure and Applied Chemistry, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...
The Standard Abbreviation (ISO4) of Journal of Rare Earths is "J. Rare Earths".ISO 4 (Information and documentation – Rules for the abbreviation of title words and titles of publications) is an international standard, defining a uniform system for the abbreviation of serial publication titles. One major use of ISO 4 is to abbreviate the names of scientific journals.

Lanthanum is a chemical element with the symbol La and atomic number 57. It is a soft, ductile, silvery-white metal that tarnishes slowly when exposed to air and is soft enough to be cut with a knife. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype.
Rare earths are actually not rare to exhibit a broad geographical distribution. The average levels of REEs in the earth's crust range from 150 to 220 ppm (ppm) which exceed the level of many other metals mined for industrial use (e.g. copper: 55 ppm and zinc: 70 ppm) (Long et al., 2010).Nonetheless, establishing and maintaining a reliable supply chain of REEs are of great concern for a number ...
The workhorse of our level line, Johnson's 9550 levels are versatile enough to tackle any job, from rough carpentry to finish carpentry. The levels feature heavy-duty aluminum frames for strength and durability, and push-button removable end caps for flush work. Strong rare earth magnets hold the level securely in place on ferrous surfaces.
The Rare Earth reference is measured against an air blank. Periodically check the spectra. The periodic use of your Rare Earth cell will build a log of your instrument's wavelength accuracy for use with certification and troubleshooting should the correlation change over time.

Rare earth minerals and classification; Rare earth minerals; In the earth's crust, instead of existing as free metals, rare earth elements usually occur in the minerals of mixtures of various rare earth elements and nonmetals. More than 200 kinds of minerals have been discovered to contain essential or significant REE currently, and bastnaesite, monazite and xenotime are the three most ...

Apr 09, 2018· The term "rare earth elements" is actually a misnomer. REE are quite abundant within the earth's crust, falling in approximately the 50th percentile of elemental abundances , and in fact are about 200 times more abundant than gold .The name originated from their discovery in the 18th century, where at the time they were discovered with a class of oxides called "earths" and the ...
Rare earth elements is a group of elements that expands from lanthanum to lutetium, which exhibit similar physical and chemical properties.It can be found in rocks and minerals. This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034.
Rare Earth is an American soul band affiliated with Motown's Rare Earth record label (named after the band), which prospered from 1970–1972. Although not the first white band signed to Motown, Rare Earth was the first big hit-making act signed by Motown that consisted only of white members. (None of the previously signed all-white acts - The Rustix, The Dalton Boys, or The Underdogs - had ...
