High Intensity Discharge headlights often use what are commonly called "salts" to modify the color and enhance the efficiency of the light output. DyI₃ is one of several of the commonly used salts.

Information Sources

Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

What are the electrical and magnetic properties of Dysprosium?

The amazing reducing agent

Dysprosium can be reacted with iodine metal under nitrogen to produce DyI2. This compound can then be thrown in some DME (under N2 of course) and heated to produce DyI2((DME)3. This stuff can reduce Naphthalene! This crazy reaction should be included in this article. Check out J. Am. Chem.

Production discrepancy

In one paragraph the article states that annual global production is about 100 tonnes, 99% of which is from China. In the next paragraph, it states that the Browns Range plant in Western Australia is producing 50 tonnes per annum. Which is 50%. To be sure, the first figures date from 2009/2010, while the second is from 2018. But it is a discrepancy that needs resolving to make this portion of the article credible. To compound the issue, the ABC article cited which is the source of the 50 tonnes per annum in Western Australia statement, goes on to say this is 15% so the source itself needs verification.

Hardness

The 84th edition of the Rubber Bible says it is "soft enough to be cut with a knife". Double sharp (talk) 14:05, 5 July 2019 (UTC)

I know the CRC bricks, but why isn't there a single wikilink that lists: "CRC ed 84=1962"? -DePiep (talk) 16:15, 5 July 2019 (UTC)

Imaginary names reserved for (non-existing) minerals

"kozoite-(Dy)" and "tengerite-(Dy)" - no such minerals are known and the cited paper is WRONGLY UNDERSTOOD and/or wrongly cited (e.g., with repeating this obvious error here). No approved dysprosium-dominant minerals are currently known at all. A mineral is, exclusively, a substance that is crystalline and formed naturally - not with a purpose, in a lab. This was wrongly introduced here. These dysprosium carbonates are SYNTHETIC and, as such, ARE ONLY SIMILAR to minerals like tengerite-(Y) or kozoite-(La) or kozoite-(Nd); and, as such cannot be named using mineral names. The more, the International Mineralogical Association is the only institution to approve/disprove mineral names. These imaginary names are now deleted. This is yet another example where mineralogy is completely wrongly understood in Wikipedia. Mineralogical names are reserved for minerals (confirmed, existing, approved by the IMA commission - exclusively). Even if some day such Dy-dominant minerals are to be found, they first need to pass the acceptance process within the IMA commission. To anticede the possible local "concrete" and drawing back my edit - I kindly suggest reading this: https://www.ima-mineralogy.org; and this: https://www.ima-mineralogy.org/Minlist.htm; and this: https://www.ima-mineralogy.org/Mission.htm Eudialytos (talk) 22:49, 12 May 2020 (UTC)Eudialytos (talk) 22:37, 12 May 2020 (UTC)
