Occurrence nature

Occurrence. Naturally occurring nitrogen (N2) makes up 78% (by volume) of the earth atmosphere. Nitrogen is relatively unabundant in the crustal rocks. The major minerals are saltpetre (KN03) andNaN03 (Chile saltpetre).

Occurrence Natural glass is rare but exists in the form of obsidian in areas of volcanic activity and meteor strikes. Excellent sand for glassmaking occurs in Virginia (James River), Pennsylvania, Massachusetts, New Jersey, West Virginia, Illinois, and Maryland also in southern Germany and the Czech Republic. 

Occurrence Naturally in Madagascar, Ceylon, Mexico, Korea, Austria, the former U.S.S.R., and China. Also produced synthetically by heating petroleum coke to approximately 3000C in an electric resistance furnace. Approximately 70% used inU.S. is synthetic.

A special kind of nonaqueous foam known as bituminous froth is produced during the application of the hot-water flotation process to Athabasca oil sands, a large-scale commercial application of mined oil sands technology. These froths are multiphase, composed of oil, water gas, and solids, and form an interesting kind of petroleum industry foam. This chapter presents a review of the occurrence, nature, properties, and treatment of bituminous froths.

With an increase in our knowledge of the occurrence, nature, and mechanism of polymer miscibility many new ways of modifying the properties of existing polymers may be found in the future. 

Ignition the process of starting a combustion process through the input of energy. Ignition occurs when the temperature of a substance is raised to the point at which its molecules will react spontaneously with an oxidizer and combustion occurs Incident an event or sequence of events or occurrences, natural or man-made, that results in undesirable consequences and requires and emergency response to protect life and property...
