	Alkaline earth metal (Site not responding. Last check: 2007-11-03)
		The alkaline earth metals are the series of elements in Group 2 of the periodic table : beryllium magnesium calcium strontium barium and radium (not always considered due to its short half-life).
		These were named alkaline earths because of their intermediate nature between alkalis (oxides of the alkali metals) and the rare earths (oxides of rare earth metals).
		The alkaline earth metals are silvery colored low density metals which react readily with halogens to form ionic salts and with water though not as rapidly as the alkali metals to form strongly alkaline (basic) hydroxides.

	Alkali - Wikipedia, the free encyclopedia
		In chemistry, an alkali is a specific type of base, formed as a carbonate, hydroxide or other ionic salt of an alkali metal or alkali earth metal element.
		The word alkali or the adjective alkaline are frequently used to refer to all bases, since most common bases are alkalis, although such use is really a synecdoche.
		It is common to speak of "measuring the alkalinity of soil" when you actually mean measuring the pH (base property).

		Preferably, the alkaline metal compound is present during reaction of the aqueous solution of metal salt and aqueous solution of a metal cyanide salt.
		Metals which are especially suitable for use are metals of group la, 2a, 2b and 8 of the Periodic Table of the Elements of Handbook of Chemistry and Physics.
		Therefore, the present invention further relates to double metal cyanide catalyst prepared from a metal salt and a metal cyanide salt in which the molar ratio of metal derived from the metal salt to metal derived from the metal cyanide salt is at least 2.

	Method for decomposing nitrogen fluoride or sulfur fluoride and decomposing reagent used therefor - US Patent 6416726 (Site not responding. Last check: 2007-11-03)
		The alkaline earth metal element in the reagent acts to decompose nitrogen fluoride and sulfur fluoride, in the presence of the elemental carbon.
		If the relative amount of the alkaline earth element is too small, the relative ratio of the amount of the alkaline earth metal element, contributing to the decomposition reaction, to the amount of carbon lowers as the reaction proceeds, and it becomes impossible to obtain a high decomposition ratio.
		The alkali metal element, for example, K, may be contained in the reagent by incorporating the same in the form of a compound such as a hydroxide, a carbonate, a phosphate, an aluminate, a nitrate or a sulfate.

		As a result, materials such as, for example, coating materials that incorporate alkaline earth metal aluminates as a luminescent material have generally not been water-based, have generally required at least two coatings, and have required materials that are expensive enough so that the coating costs range upward from $30 per square foot.
		Generally, it was discovered that alkaline earth metal aluminates are not capable of being added in a powder form to water-based materials because the aluminates are sensitive to water.
		As used herein, the term"alkaline earth metal aluminate" refers to any alkaline earth metal aluminate material whose luminescent properties are diminished or deactivated when in contact with water and/or metal contaminants and that absorbs energy when illuminated and thereafter glows or luminesces when darkened.

		In this example, metal oxide layer 104 has at least one alkaline earth metal A and at least one metal B and can be represented by the general formula ABO.sub.3, although it will be appreciated that the process is not intended to be limited to this particular material.
		The initial ratio of the alkaline earth metal A to the metal B is greater than 1 (40).
		To grow metal oxides that do not comprise an alkaline earth metal, it may be desirable to expose the substrate to an alkaline earth metal source during formation of the metal oxide to facilitate oxidation of the metal.

		The alkali metals are silvery colored, soft, low density metals, which react readily with halogens to form ionic salts, and with water to form strongly alkaline (basic) hydroxides.
		These elements all have one electron in their outermost shell, so the energetically preferred state of achieving a filled electron shell is to lose one electron to form a singly charged positive ion.
		Hydrogen, with a solitary electron, nominally belongs in the alkali metals group.

	Therapeutic dentifrices in unlined container and methods - Patent 4159280
		The reaction of silica with alkaline earth metal is conducted at ambient temperature and with agitation.
		The time period over which the alkali metal silicate and/or sulfuric acid are added to the reactor can be predetermined and is generally based on the volume of the reactor and the difficulties in control on the volume of the reactor and the difficulties in control of the temperature and agitation.
		It has been found that this amount of alkaline earth metal is sufficient to overcome problems with staining and corrosion of unlined aluminum tubes, but is insufficient to interfere with the fluoride availability in the paste and thus not interfere with the therapeutic action of the dentifrice composition.

	Waste Minimization in Metal Parts Cleaning (Site not responding. Last check: 2007-11-03)
		Alkaline cleaners are solutions of inorganic salts often used in heated soak tanks to remove heavy oily soils and some solid soils.
		Removal of oil contaminants prior to welding The welding of metal parts which have residual oils present on or near the weld leads to the formation of carbonaceous deposits due to pyrolysis of organics at high temperatures.
		Avoid unnecessary loading When using an alkaline cleaner, alkalinity may be reduced by the acidity of the soils removed, reaction of the alkali with carbon dioxide in the air used for agitation, and reaction of the cleaner components with hard water salts (Spring, 1963).

	The Potential for Beneficial Reuse of Coal Fly Ash in Southwest Virginia Mining Environments
		Alkaline fly ash can aid in the reclamation of acidic spoils and refuse piles, although one-time ash applications do not appear to be effective in maintaining increased pH if pyrite oxidation is not completely stopped and neutralized.
		In this scenario of insufficient amounts of added alkalinity to limit the onset of acid leaching conditions, the heavy metal content of the leachates was actually higher than that of the control treatments, indicating that ash-bound heavy metals were being stripped away by the refuse generated acid mine drainage.
		Alkaline fly ash from the Clinch River Plant (AEP) was used for all treatments along with the same highly reactive (2.2% pyritic-S) refuse material used in the earlier leaching columns.

		For example, calcium ions are a major component of your bones, magnesium is used in a variety of metal alloys, strontium is used in television tubes, and barium compounds are used as X-ray contrast agents.
		Ca, Sr and Ba are reactive towards air and water in their elemental (metal) form, but much less so than their alkali metal counterparts.
		The other alkali metals are all flammable and water reactive, so special care needs to be taken in using these and a proper Class D extinguisher should be available.

		The Idaho National Engineering and Environmental Laboratory (INEEL) has devised and modeled a novel alkaline metal-based hydrogen generation process that has the potential to significantly reduce the cost of compressing and liquefying hydrogen.
		The unique characteristic of an alkaline metal / water reaction is that the reaction will take place at elevated pressures.
		At elevated pressures, the hydrogen gas may be dispensed directly into vehicles as a compressed fuel, or the stored energy of the compressed gas may be incorporated into pressure letdown processes to liquefy a portion or perhaps all of the hydrogen produced by the process.
