Talk:Barium metaphosphate

Page contents not supported in other languages.
From Wikipedia, the free encyclopedia

The article is one of a series of articles inflicted on Wikipedia by beginning US undergraduate students. They write about ultra-esoteric compounds (I guess because they are unsupervised). My understanding is that these are honor students at a large institution where they use Wikipedia as homework site. I have spent a lot of time trying to rectify the articles coming from this group, although fortunately most are rejected at this stage. The feeling we get is that the students dont really care, their requirement is only to load something is a sandbox to be checked, but a few of these students go farther and attempt to upload into the mainspace. In sum, the article is well intentioned but so flawed that a total rewrite would be required.

  • The sources are URLs seemingly obtained unselectively by a well intentioned but inexperienced person.
  • The drawing is very wrong.
  • his article fails even the mild standards of notability set by the Wikipedia Chemistry project.
  • Notice that the author (User:REACTuiuc123) has not contributed to Wikipedia since this homework assignment was submitted.--Smokefoot (talk) 05:30, 21 February 2014 (UTC)}}[reply]

Removed from article

[edit]

I have removed the following content from the article because much of it is not intelligible and some of it is clearly wrong as written. It needs to be rewritten before being reincluded in the article. -- Ed (Edgar181) 12:00, 22 February 2014 (UTC)[reply]

The testing barium metaphosphate goes through is in special optical glass materials and functions as the addictive of phosphate glass and fluophosphate glass. When a certain amount of barium metaphosphate is put into the fluoride glass, the anti~opacification and light absorption of the glass will be changed. That basically means that the increase of the barium metaphosphate will lead to the increase in glass thermostability, which is the amount of heat a piece of glass can handle. This change will not happen when barium metaphosphate reflects the frequency range of ultraviolet transmittance. The addition of barium metaphosphate will delete the ultraviolet absorption of fluoride and move the wavelength to short wave direction.<ref>{{cite web|author=Shenghe Mining Co.,Ltd. |url=http://www.shenghemining.com/product/barium-en.html |title=Barium metaphosphate |publisher=Shenghe Mining |date= |accessdate=2012-10-23}}</ref> Also, its input will greatly weaken the input of infrared ray. It can not only move the infrared absorption band of the glass to shortwave direction, but also reduce the light transmittance of glass within the range of the infrared ray.<ref>{{cite paper|url=http://www.bariumchemicals.com/Specs/22.pdf |title=Technical Data Sheet: Barium Metaphosphate |publisher=Barium Chemicals |date= |accessdate=2012-10-23}}</ref> One of the experiments that was done on barium metaphosphate was the zinc barium metaphosphate glasses. This study was for the learning of the infrared spectra, and of molar volume and of the variation of glass transition temperature with the ZnO content is discussed in order to find out the effect of Zn<sup>2+</sup> in glass.<ref>{{cite paper|url=http://www.sciencedirect.com/science/article/pii/S0025540804000364 |title=Properties of vitreous barium zinc mixed metaphosphate |publisher=Science Direct |date= |accessdate=2012-10-23}}</ref> Also, there have been other experiments done with barium metaphosphate which involve the dissolution of nitrogen in alkali-barium-metaphosphate, which causes the nitrogen to melt. The amount of nitrogen in these metaphosphate melts decreased as the size of the alkali ions increase. Also, the dissolution rate in water increased with increasing alkali ion size.<ref>{{cite paper|url=http://www.springerlink.com/content/l788608463v24234/ |title=Nitrogen dissolution in alkali-barium-metaphosphate melts |publisher=Journal of Material Sciences |date= |accessdate=2012-10-23}}</ref>
