The global industrial production of ammonia for 2012 was anticipated to be 198,000,000 tonnes (195,000,000 long tons; 218,000,000 short tons), a 35% increase over the estimated 2006 global output of 146,500,000 tonnes (144,200,000 long tons; 161,500,000 short tons).H 3 boils at â33.34 Â°C (â28.012 Â°F) at a pressure of one atmosphere, so the liquid must be stored under pressure or at low temperature. Household ammonia or ammonium hydroxide is a solution of NH 3 in water.
While barium fluoride windows are less resistant to water than calcium fluoride, BaF 2 windows are the most resistant optical fluoride to high-energy radiation, but feature lower UV transmittance. BaF 2 has a Knoop hardness of 82. Note: These optical windows are very sensitive to thermal shock. Barium fluoride is a fast scintillator and can be used to detect X-rays, gamma rays, or other high energy particles such as 511 keV gamma photons in Positron Emission Tomography (PET).
Ammonium fluoride is a white crystalline solid. Ammonium fluoride is soluble in water. Ammonium fluoride is noncombustible. Ammonium fluoride is corrosive to aluminum. Ammonium fluoride is used in chemical analysis, in brewing, and as a preservative for wood.
