Nitride | chemical compound | Britannica

Nitride, any of a class of chemical compounds in which nitrogen is combined with an element of similar or lower electronegativity, such as boron, silicon, and most metals. Nitrides contain the nitride ion (N3−), and, similar to carbides, nitrides can be classified into three general categories:

Carbon - Wikipedia

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.

Simultaneous nitrification and aerobic denitrification (SNaD) is a preferred method for single stage total nitrogen (TN) removal, which was recently proposed to improve wastewater treatment plant design. However, SNaD processes are prone to inhibition by toxicant loading with free cyanide (FCN) possessing the highest inhibitory effect on such processes, rendering these processes ineffective.

Top 9 Methods of Carburising | Case-Hardening | Steel .

Plain cyanide salt results in high nitrogen, low carbon case, but presence of chlorides in the bath hinders nitrogen pick-up, and favours absorption of carbon into steel. Fig. 8.12 can be used to assess the case depth in liquid carburising, which is much faster than pack-carburising.

The Interplay Between Water Limitation, Dhurrin, and .

Sorghum bicolor (L.) Moench produces the nitrogen-containing natural product dhurrin that provides chemical defense against herbivores and pathogens via the release of toxic hydrogen cyanide gas. Drought can increase dhurrin in shoot tissues to concentrations toxic to livestock. As dhurrin is also a remobilizable store of reduced nitrogen and plays a role in stress mitigation, reductions in .

Hydrogen cyanide in nitrogen-rich atmospheres of rocky .

Hydrogen cyanide (HCN) is a key feedstock molecule for the production of life's building blocks. The formation of HCN in an N 2-rich atmospheres requires first that the triple bond between N≡N be severed, and then that the atomic nitrogen find a carbon atom.These two tasks can be accomplished via photochemistry, lightning, impacts, or volcanism.

Liquid Nitriding

Liquid nitriding or nitriding in a molten salt bath employs the same temperature range as gas nitriding, which is 510 to 580°C. The case hardening medium is a molten, nitrogen-bearing, fused-salt bath containing either cyanides or cyanates.

Cyanide - an overview | ScienceDirect Topics

Cyanide refers to a highly toxic chemical compound containing one atom of carbon and nitrogen each. Deaths due to cyanide poisoning are relatively rare largely due to its limited availability.

Abstract: Liquid nitriding or nitriding in a molten salt bath employs the same temperature range as gas nitriding, which is 510 to 580°C. The case hardening medium is a molten, nitrogen-bearing, fused-salt bath containing either cyanides or cyanates. Unlike liquid carburizing and cyaniding, which employ baths of similar compositions, liquid nitriding is a sub-critical casehardening process .
