The Haber process, also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. It converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using finely divided iron metal as a catalyst:
In chemistry, a nitride is a chemical compound of nitrogen. Nitrides can be inorganic or organic, ionic or covalent. The nitride anion, N3- ion, is very elusive but compounds of nitride are numerous, although rarely naturally occurring. Some nitrides have a found applications, such as wear-resistant coatings (e.g., titanium nitride, TiN), hard ceramic materials (e.g., silicon nitride, Si3N4), and semiconductors (e.g., gallium nitride, GaN). The development of GaN-based light emitting diodes was recognized by the 2014 Nobel Prize in Physics. Metal nitrido complexes are also common.
Lithium nitride is an inorganic compound with the chemical formula Li3N. It is the only stable alkali metal nitride. It is a reddish-pink solid with a high melting point.
Tetrasulfur tetranitride is an inorganic compound with the formula S4N4. This vivid orange, opaque, crystalline explosive is the most important binary sulfur nitride, which are compounds that contain only the elements sulfur and nitrogen. It is a precursor to many S-N compounds and has attracted wide interest for its unusual structure and bonding.
Lanthanum chloride is the inorganic compound with the formula LaCl3. It is a common salt of lanthanum which is mainly used in research. It is a white solid that is highly soluble in water and alcohols.
Lithium amide or lithium azanide is an inorganic compound with the chemical formula LiNH2. It is a white solid with a tetragonal crystal structure. Lithium amide can be made by treating lithium metal with liquid ammonia:
Transition metal dinitrogen complexes are coordination compounds that contain transition metals as ion centers the dinitrogen molecules (N2) as ligands.
In chemistry, ammonolysis (/am·mo·nol·y·sis/) is the process of splitting ammonia into . Ammonolysis reactions can be conducted with organic compounds to produce amines (molecules containing a nitrogen atom with a lone pair, :N), or with inorganic compounds to produce nitrides. This reaction is analogous to hydrolysis in which water molecules are split. Similar to water, liquid ammonia also undergoes auto-ionization, , where the rate constant is k = 1.9 × 10-38.
Abiological nitrogen fixation describes chemical processes that fix (react with) N2, usually with the goal of generating ammonia. The dominant technology for abiological nitrogen fixation is the Haber process, which uses iron-based heterogeneous catalysts and H2 to convert N2 to NH3. This article focuses on homogeneous (soluble) catalysts for the same or similar conversions.
Praseodymium(III) nitride is a binary inorganic compound of praseodymium and nitrogen. Its chemical formula is PrN. The compound forms black crystals, and reacts with water.
Neodymium(III) nitride is a chemical compound of neodymium and nitrogen with the formula NdN in which neodymium exhibits the +3 oxidation state and nitrogen exhibits the -3 oxidation state. It is ferromagnetic, like gadolinium(III) nitride, terbium(III) nitride and dysprosium(III) nitride. Neodymium(III) nitride is not usually stoichiometric, and it is very hard to create pure stoichiometric neodymium nitride.
Main-group element-mediated activation of dinitrogen is the N2 activation facilitated by reactive main group element centered molecules (e.g., low valent main group metal calcium, dicoordinate borylene, boron radical, carbene, etc.).
Erbium nitride is a binary inorganic compound of erbium and nitrogen with the chemical formula ErN.
Ytterbium(III) nitride is a binary inorganic compound of ytterbium and nitrogen with the chemical formula YbN.
Samarium(III) nitride is a binary inorganic compound of samarium and nitrogen with the chemical formula SmN.
Cerium nitride is a binary inorganic compound of cerium and nitrogen with the chemical formula CeN.
Neptunium nitride is a binary inorganic compound of neptunium and nitrogen with the chemical formula NpN.
Americium nitride is a binary inorganic compound of americium and nitride with the chemical formula AmN.
Gadolinium(III) nitride is a binary inorganic compound of gadolinium and nitrogen with the chemical formula GdN.
Americium trihydride is a binary inorganic compound of americium and hydrogen with the chemical formula AmH3.
