AMMONIA GAS (7664-41-7) Anhydrous, compressed gas or cryogenic liquid. Difficult to ignite, but can detonate in confined spaces in fire. Reacts violently with strong oxidizers, acids (nitric, hydrochloric, sulfuric, picric, hydrobromic, hydrochlorous, etc.). Shock-, temperature-, and pressure-sensitive compounds are formed with antimony, chlorine, germanium compounds, halogens, heavy metals, hydrocarbons, mercury oxide, silver compounds (azides, chlorides, nitrates, oxides). Fire and/or explosions may be caused by contact with acetaldehyde, acrolein, aldehydes, alkylene oxides, amides, antimony, boron, boron halides. 

IODINE (7553-56-2) A powerful oxidizer. Material or vapors react violently with reducing agents, combustible materials, alkali metals, acetylene, acetaldehyde, antimony, boron, bromine pentafluoride, bromine trifluoride, calcium hydride, cesium, cesium oxide, chlorine trifluoride, copper hydride, dipropylmercury, fluoride, francium, lithium, metal acetylides, metal carbides, nickel monoxide, nitryl fluoride, perchloryl perchlorate, polyacetylene, powdered metals, rubidium, phosphorus, sodium, sodium phosphinate, sulfur, sulfur trioxide, tetraamine, trioxygen difluoride. Forms heat- or shock-sensitive compounds with ammonia, silver azide, potassium, sodium, oxygen difluoride. Incompatible with aluminum-titanium alloy, barium acetylide, ethanol, formamide, halogens, mercmic oxide, mercurous chloride, oxygen, pyridine, pyrogallic acid, salicylic acid sodium hydride, sodium salicylate, sulfides, and other materials. 

The four digestion schemes were applied to a second lubricating grease sample with lithium soap thickener. These results are shown in Table 5. The sulfated ash digestion resulted in loss of antimony, boron, and phosphorous, while lithium and zinc remained consistent with expected values. 

Some elements exhibit properties that lie between definite nonmetals and definite metals. These elements, historically called metalloids, mimic metals in that they are solid and semiconductors. They include arsenic, antimony, boron, carbon, germanium, polonium, phosphorus, selenium, silicon, and tellurium. 

A unique approach to the controlled design of such systems as macrocyclic polylactones, polylactams and related compounds has been developed [1]. The synthesis of these substances, called biomimetic macrocyclic molecules by reason of their resemblance to naturally occuring ionophores (such as valinomycin, nonacdn, enniatin and enterobactin [2-5]), is carried out by a covalent-template method. This description arises from the use of elements forming covalent bonds (tin, silicon, antimony, boron) as matrices. 

In addition to minerals which are known to be dietary essentials, there a number which may be consumed in relatively large amounts but which have, as far as is known, no function in the body. Indeed, excessive accumulation of these minerals may be dangerous, and a number of them are well known as poisons. Such elements include aluminium, arsenic, antimony, boron, cadmium, caesium, germanium, lead, mercury, silver and strontium. 

The second approach is to incorporate small amounts of highly efficient flame retardant additives as minor constituents of the plastics composition. Such additives are generally based on antimony, boron, chlorine, bromine or phosphorus, or a combination of these.
