	Strontium - LoveToKnow 1911
		Strontium chloride, SrC1 2.6H 2 O, is obtained by dissolving the carbonate in hydrochloric acid, or by fusing the carbonate with calcium chloride and extracting the melt with water.
		Strontium carbide, SrC2, is obtained by heating strontium carbonate with carbon in the electric furnace.
		Strontium salts may be recognized by the characteristic crimson colour they impart to the flame of the Bunsen burner and by the precipitation of the insoluble sulphate.

	strontium carbonate
		Strontium carbonate is derived from strontium, one of the alkaline-earth metal elements (main Group IIa of the periodic table).
		Strontium alone (in the form of the strontium-90 isotope) is notable as the principal health hazard in radioactive fallout; at the same time, however, the element has been used for the treatment of bone cancer.
		Strontium carbonate is insoluble in water, but reacts with acids and will dissolve in carbonic acid and ammonium salts.

	Strontium: Breakthrough Against Osteoporosis
		Patients in the strontium group increased lumbar bone mineral density by an average of 14.4 percent and femoral neck BMD an average of 8.3 percent.
		Epidemiologic studies have shown that strontium concentrations of 6 to 10 mg/liter in the water supply are associated with a reduced incidence of cavities.
		Strontium in doses up to 1.7 g/day appears to offer a safe, effective and inexpensive approach to preventing and reversing osteoporosis and may be of benefit in patients with osteoarthritis and cancer with bone metastases, as well as possibly helping to prevent dental cavities.

	QUIMICA DEL ESTRONCIO
		Ceramics and Sanitary ceramic: Strontium Carbonate is used in glazing and enamelling of ceramics for china, reinforcing its resistance to abrasion and scratching and avoiding the formation of bubbles in the baking process of the frits.
		Pyrotechnics: Strontium Carbonate is used in pyrotechnics (fireworks), flares and tracers, for civilian and military end-use as a result of the bright red colour produced by its combustion.
		Strontium Carbonate is used in numerous applications of glass for usage in optics, crystal ware, lighting, glass fibre, laboratory and pharmaceutical glass, etc. Improving properties such as increase in toughness and scratch resistance, gloss increase ease of polishing, etc.

	Flux for coated welding electrode - Patent 5308698
		The flux includes in parts by weight 5 to 35 strontium carbonate, 5 to 35 total metal carbonate compound, 0 to 20 manganese with at least 5 manganese present when less than 0.5 weight percent manganese is present in the core wire, 10 to 40 fluoride compound and 5 to 45 oxide compound.
		Sample number 2 contained 10 parts by weight strontium carbonate in the flux which was found to improve welding operability and especially welding operability during overhead welding.
		Specific carbonates that may be inserted into the flux include calcium carbonate, strontium carbonate, lithium carbonate, magnesium carbonate, lanthanum carbonate and manganese carbonate, dolomite, and any combination thereof provided at least 3 parts by weight strontium carbonate are present.

	Strontium (Sr) and water
		Strontium ferrite is applied in permanent ceramic magnets that are highly coercive and can be applied in small engines because of its resistance to heat and corrosion.
		Strontium is usually immobile in the environment, because of rapid precipitation as strontium carbonate, or because it is applied in shells.
		The risk of radioactive strontium intake is mainly based on its carcinogenic and mutagenic mechanism, problems that occur in cell division, and possible increased infant mortality.

	Tropic Marin Bio-Strontium
		A sufficient supply of strontium and carbon dioxide is as essential for the growth and well-being of reef-building corals as calcium.
		Bio-Strontium creates a natural environment in the aquarium and delivers strontium and carbon dioxide in a natural, biologically-available ionically balanced form.
		In a reef aquarium the concentration of strontium decreases quickly through biological processes, precipitation and by the use in calcareous animals.

	Mineral Gallery - the Carbonates Class
		The carbonates and related nitrates and borates are common constituents of the earth's near-surface crust.
		As long as the triangles of the anionic group fall in a plane parallel with the plane of the triangle and all other bonds in the structure, when viewed perpendicular to this plane, are multiples of three, and are evenly separated from each other, the mineral will have a trigonal symmetry.
		Typical carbonates are transparent, lightly colored with a white streak, average to above average in density, soft with good to perfect cleavage, soluble to at least some degree in acidic solutions, and tend to originate in sedimentary and oxidizing environments with the exception of carbonatite igneous intrusions.

	It's Elemental - The Element Strontium
		Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride (SrCl
		The strontium chloride, usually mixed with potassium chloride (KCl), is then melted and electrolyzed, forming strontium and chlorine gas (Cl Most of the strontium produced today is used in the manufacture of color television picture tubes.
		Strontium carbonate is also used to make certain kinds of glass and is the base material for making most other strontium compounds.

	SmartBodyz.com -- Strontium carbonate (element, supplements, use, information)
		Mention strontium to most people, and they will almost always immediately think of strontium-90, a highly dangerous, radioactive component of nuclear fallout produced during atmospheric testing of nuclear weapons in the 1950s.
		Strontium is nontoxic even when administered in large doses for prolonged periods.
		J.Y. Reginster, one of the principal strontium researchers, cautions that co-administration of strontium with calcium appears to impair strontium absorption so strontium carbonate should be taken on an empty stomach and not be taken with other multi-minerals that usually include calcium.

	Magnetism - Wikipedia, the free encyclopedia
		Technology has expanded the availability of magnetic materials to include various manmade products, all based, however, on naturally magnetic elements.
		Ceramic, or ferrite, magnets are made of a sintered composite of powdered iron oxide and barium/strontium carbonate ceramic.
		Due to the low cost of the materials and manufacturing methods, inexpensive magnets (or nonmagnetized ferromagnetic cores, for use in electronic component such as radio antennas, for example) of various shapes can be easily mass produced.

	USGS Minerals Information: Strontium
		Strontium commonly occurs in nature, averaging 0.034% of all igneous rock; only two minerals, celestite (strontium sulfate) and strontianite (strontium carbonate), however, contain strontium in sufficient quantities to make its recovery practical.
		Of the two, celestite occurs much more frequently in sedimentary deposits of sufficient size to make development of mining facilities attractive.
		Strontianite would be the more useful of the two common minerals because strontium is used most often in the carbonate form, but few deposits have been discovered that are suitable for development.
