= Barium Metaphosphate =

Barium Metaphosphate is an inorganic molecular, and is made up of Ba 46.508 % P 20.979 % and O 32.511 %. Most of its use is during testing in a laboratory, which means it is a technical compound. BaPO3 is prepared through a reaction of barium carbonate with excess phosphoric phosphoric acid and using heat in the reaction: BaCO3 + H3PO4 -> BaPO3. The chemical comes in a white powder.

History
The testing Barium Metaphosphate goes through many types of glass materials throughout its history. When an amount of barium metaphosphate is put into the fluoride glass, the light that is absorbed from the glass will be changed in a dramatic way. 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. The addition of Barium Metaphosphate will remove the ultraviolet absorption of fluoride and move the wavelength to a shorter wavelegth. Also, its input will weaken the input of infrared ray. It cannot only move the infrared absorption band of the glass to shorter wavelength, but only reduce the light transmittance of glass within the range of the infrared ray.

Projects and Studies on Barium Metaphosphate
Barium Metaphosphate has been used with zine barium metaphosphate glasses. The scientists working on this experiment were wanting to learn about the infrared spectra, and the molar volume of glass transition temperature with the zine and oxygen content. Also, there have been other experiments done with Barium Metaphosphate that 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 increased. Also, the dissolution rate in water increased with increasing alkali ion size.

Hazards and Protection
To store Barium Metaphosphate, keep it in a cool, dry, dark area in an air tight sealed container or cylinder. It should also be in a secure and labeled location. The containers or cylinders should be protected from physical damage. The handling of the Barium Metaphosphate should be very cautious to avoid direct physical contact with other chemicals. Use appropriate, approved safety equipment when using the chemicals and handling should occur in a chemical fume hood with protectice gloves, clothing and goggles. If there are small spills or leaks out of the containers of the Barium Metaphosphate, quickly get rid of it. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Cover the materials with sand or some kind of non-combustible material and you can not get water inside the containers of the Barium Metaphosphate.
