Decomposition, chemical

The largest uses of platinum group metals in electronics are ruthenium for resistors and palladium for multilayer capacitors, both applied by thick film techniques . Most anodes for brine electrolysis are coated with mixed ruthenium and titanium oxide by thermal decomposition . Chemical vapour deposition of ruthenium was patented for use on cutting tools . 

The properties of an organic tracing compound should minimize loss while in transit. There are two main sources of dye loss, non-adsorptive loss and adsorptive loss. Nonadsorptive losses can be due, among other reasons, to photochemical decomposition, chemical decay, pH effects, and biodegradation of the compound by microorganisms. Adsorption of the tracer onto both organic and inorganic substrates is often irreversible and can be a source of much loss. 

Decomposition Chemical reaction that leads to the breakdown or decomposition of a chemical into smaller molecules or elements, often with the liberation of energy and product gases. 

For this reason, the dissolution of hydrous oxides does not require a high energy of activation. If hydrous oxides are dehydrated, they become dry oxides, which therefore acquire higher resistance to anodic dissolution. The most straightforward way to obtain dry oxides is to subject hydrous oxides to thermal treatments or better to prepare them as thin surface films by a non-electrochemical technique (thermal decomposition, chemical vapor deposition, reactive sputtering, etc.).

DECOMPOSITION (Chemical). A chemical change tn which a single chemical substance is broken up into two or more other substances, which differ from each other and from the parent substance in chemical identity. Complete decomposition refers to such a condition of the products that they are not readily decomposed further, c.g.. such decomposition products as ammonia and carbon dioxide. Degnidtniim refers to gradual decomposition in which the molecule is diminished in size in small steps. See also Degradation (Chemical). 

Supercritical fluid extraction processes are particularly appropriate for the separation and isolation of biochemicals where thermal decomposition, chemical modification, and physiologically-active solvents are undesirable. Examples of these bioseparations include the extraction of oils from seeds using carbon dioxide (1), of nicotine from tobacco using carbon dioxide-water mixtures (2), and of caffeine from coffee beans again using carbon dioxide-water mixtures (3). 

Decomposition (chemical) A reaction in which the molecules of a chemical break down to its basic elements, such as carbon, hydrogen, or nitrogen, or to more simple compounds. This often occurs spontaneously, liberating considerable heat and often large volumes of gas. 

Mirrors. Silver is used in mirror production and may be deposited on glass or metals by thermal decomposition, chemical vapor deposition, electroless plating and electrodeposition, or vacuum evaporation.

At this stage it is necessary to define weathering and soil formation. Weathering may be loosely defined as the total effect of all processes involved in the disintegration (physical processes) and decomposition (chemical processes) of rocks. Soil formation is defined as the transformation of rock material into soil. The fact that the soil is a product of weathering...
