Excerpt from ERG Guide [Substances - Water-Reactive Emitting Flammable Gases ]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters feet for liquids and at least 25 meters 75 feet for solids. Move containers from fire area if you can do it without risk. Also, ks ERG Guide Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. Dike for later disposal; do not apply water unless directed to do so. Wear chemical protective clothing that is specifically recommended by the manufacturer.
It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire what is a banded iron formation ONLY; it is not effective in spill situations where direct contact with the substance is ie. Move victim to fresh air.

Ionic nitrides Lithium (Li) appears to be the only alkali metal able to form a nitride, although all the alkaline-earth metals form nitrides with the formula M 3 N 2. These compounds, which can be considered to consist of metal cations and N 3? anions, undergo hydrolysis (reaction with water) to produce ammonia and the metal hydroxide.
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. Certain metal nitrides are unstable, and most react with water to form ammonia and the oxide or hydroxide of the metal; but the nitrides of boron, vanadium , silicon, titanium , and tantalum are very refractory , resistant to chemical attack, and hard—and thus are useful as abrasives and in making crucibles.
There are two principal methods of preparing nitrides. One is by direct reaction of the elements usually at elevated temperature , shown here for the synthesis of calcium nitride, Ca 3 N 2. Another method used to form nitrides is the reduction of a metal halide or oxide in the presence of nitrogen gas, as, for example, in the preparation of aluminum nitride, AlN. Lithium Li appears to be the only alkali metal able to form a nitride, although all the alkaline-earth metals form nitrides with the formula M 3 N 2.
The largest group of nitrides are the interstitial nitrides that form with the transition metals. They are similar to the interstitial carbides, with nitrogen atoms occupying the interstices, or holes, in the lattice of close-packed metal atoms. These compounds have high melting points , are extremely hard, and are usually opaque materials that have metallic lustre and high conductivities. The interstitial nitrides are chemically inert, and few reactions involving them are known. The most characteristic reaction is hydrolysis , which is usually very slow and may require acid , as does vanadium , V, in the reaction shown below , to produce ammonia or nitrogen gas.
Because of their chemical inertness and ability to withstand high temperatures, interstitial nitrides are useful in several high-temperature applications, including their use as crucibles and high-temperature reaction vessels. Covalent binary nitrides possess a wide range of properties depending on the element to which nitrogen is bonded.
The covalent nitrides of boron , carbon , and sulfur are discussed here. Because boron and nitrogen together contain the same number of valence electrons eight as two bonded carbon atoms, boron nitride is said to be isoelectronic with elemental carbon. Boron nitride exists in two structural forms, which are analogous to two forms of carbon— graphite and diamond.
The hexagonal form, similar to graphite, has a layered structure with planar, six-membered rings of alternating boron and nitrogen atoms stacked in such a way that a boron atom in one layer is located directly over a nitrogen atom in the adjacent layer. In contrast, successive hexagonal layers of graphite are offset so that each carbon atom is directly above an interstice hole in an adjacent layer and directly over a carbon atom of alternate layers.
The properties of hexagonal boron nitride are in general different from those of graphite. While both are slippery solids, boron nitride is colourless and is a good insulator whereas graphite is black and is an electrical conductor , and boron nitride is more stable chemically than graphite. Like the analogous diamond form of carbon, cubic boron nitride is extremely hard.
It can be prepared by oxidation of hydrogen cyanide HCN. A variety of oxidizing agents can be used, including oxygen gas, O 2 , chlorine gas, Cl 2 , and nitrogen dioxide gas, NO 2. Sulfur forms a variety of covalent binary nitrides, but the two most interesting ones are tetrasulfur tetranitride, S 4 N 4 , and disulfur dinitride, S 2 N 2 , because they are precursors to an unusual polymer called polythiazyl, SN x.
This polymeric sulfur nitride is unusual because, even though it is composed solely of two nonmetals, it exhibits some properties normally associated only with metals. The crystals are stable in air but will explode in response to shock or friction. The compound has a cage structure with a plane of four nitrogen atoms with two sulfur atoms above and below the plane.
This compound has an essentially square structure with alternating sulfur and nitrogen atoms. This rather amazing material has a bronze colour, a metallic lustre, and the electrical and thermal conductivity of a metal.
