The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
log 10 of anydrous ammonia vapor pressure. ... Right of the III. point the frozen component is ammonia. [6] Vapor over aqueous ammonia solution [7] Temp. %wt NH 3:
When supplying a temperature value (the numerical value in either °C, °F or K), the infobox will calculate and present all three temperatures. Only one of the three _C, _F, _K values may be entered. E.g.: |MeltingPtC=100 shows: 100 °C; 212 °F; 373 K. To show a temperature range, simply add the corresponding _CH high value (_FH, _KH). E.g.:
Ammonia is found throughout the Solar System on Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, among other places: on smaller, icy bodies such as Pluto, ammonia can act as a geologically important antifreeze, as a mixture of water and ammonia can have a melting point as low as −100 °C (−148 °F; 173 K) if the ammonia concentration is ...
{{Periodic table (melting point)|state=expanded}} or {{Periodic table (melting point)|state=collapsed}}This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. [13] Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than ...
HIGH POINT, N.C. (WGHP) — Hazmat crews are at the scene of a plant in High Point due to an ammonia leak. Officials say the ammonia leak is at the Dairy Fresh plant on 1350 West Fairfield Road.
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
