The Birkeland–Eyde process was one of the competing industrial processes in the beginning of nitrogen-based fertilizer production. It is a multi-step nitrogen fixation reaction that uses electrical arcs to react atmospheric nitrogen (N 2 ) with oxygen (O 2 ), ultimately producing nitric acid (HNO 3 ) with water. [ 1 ]
The values in an NPK fertilizer label are related to the concentrations (by weight) of phosphorus and potassium elements as follows: P 2 O 5 consists of 56.4% elemental oxygen and 43.6% elemental phosphorus by weight. Therefore, the elemental phosphorus percentage of a fertilizer is 0.436 times its P value. K
(NH 4) 2 HPO 4 (s) ⇌ NH 3 (g) + (NH 4)H 2 PO 4 (s) At 100 °C, the dissociation pressure of diammonium phosphate is approximately 5 mmHg. [3] According to the diammonium phosphate MSDS from CF Industries, Inc., decomposition starts as low as 70 °C: "Hazardous Decomposition Products: Gradually loses ammonia when exposed to air at room ...
In May 2018, Nutrien announced it would sell to Tianqi Lithium a 24% stake in the Chilean mining company Sociedad Química y Minera (SQM) for approximately $4.1 billion. [8] [9] Tianqi was to purchase 62.5 million SQM A shares for $65 each. Nutrien needed to satisfy the Chinese and Indian regulators because of concerns it would corner the ...
The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
