Aluminum is the most abundant metal in the earth's crust and is always found combined with other elements such as oxygen, silicon, and fluorine. At higher firing temperatures, the Sr3Al2O6 undergoes transformation to SrAl2O4. Strontium aluminate with Eu 2+ and Dy 3+ has been at the forefront of emerging applications for storage phosphors since its discovery in 1996. IDENTIFICATION. Seriously cool. 4770 Buford Highway. The mineral works along with calcium to improve bone density and reduce the risks of osteoporosis. A large portion of the strontium will accumulate in bone. The strontium aluminate paint products offered here are non-allergic and skin-friendly.

Phosphorbased polymer composites were prepared using a melt mixing and extrusion method. It is not approved in the USA. As the sensor component of the NLRP3 inflammasome, plays a crucial role in innate immunity and inflammation. The glow intensity depends on the particle size; generally, the bigger the particles, the better the glow. Use in Canada, After excitation at 320 nm . Check out our strontium aluminate ring selection for the very best in unique or custom, handmade pieces from our shops. petrus bitbyter Oh, don't be an isotope. Strontium's benefits are unlike other nutrients on this planet. Strontium absorption also has effects on the absorption of calcium, magnesium and phosphate ions. Fig. Oak Ridge National Lab . Due to the fact that strontium (Sr) is not involved in the scope of supervision of drinking water in China, the Sr concentration in public drinking water and its related health risks have been neglected for a long time. Top of Page. Chamblee, GA 30341-3717. In the body, strontium behaves very much like calcium. These products do not improvise the use of any kind of chemical additives that may be harmful to your health. Offering a wide range of optimum quality cosmetic products, the site features some of the most reputed and reliable strontium aluminate paint. Our product specifically was deigned harmless under the OSHA (Occupational Safety and Health Administration) Hazard Communication Standard 29 CFR 1900.1200[4]. 2D crystal structure of strontium aluminate. Strontium aluminate phosphor is usually fired at about 1250 C, though higher temperatures are possible. John R Rich the Newsgroup Wacko Jan 1, 1970 0 Oct 4, 2005 #6 Glows in the dark, about 10x brighter and longer than the classic ZnS stuff. General description. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. By controlling the raw material ratio (Sr/Al), the effects of phase composition on subsequent spectroscopic properties of phosphors are studied. It reacts with water quicker than calcium, which is placed directly above strontium in the periodic chart, and slower than barium, placed directly below strontium. Glow in the Dark. Strontium is a mineral and alkaline earth metal like calcium, and it seems to work similarly to calcium in the body with its main benefit being a boost to bone health. Strontium aluminate Luminous powder refers to the materials that can continuously glow for a period of over 12 hours after being irradiated by a light source such as sunlight and long-wave ultraviolet light for a short period of time. . Strontium aluminate, 100% 3 Hazards identification, Hazard description:Xi Irritant , Information pertaining to particular dangers for man and environment, R 36/37/38 Irritating to eyes, respiratory system and skin. These pigments are sometimes called GID GDI even LIT. Long persistent blue-green phosphor. Other pertinent literature is also presented, but is described in less detail than the key studies. When activated with a suitable dopant, it acts as a photoluminescent phosphor with long persistence of phosphorescence. It is one of the more expensive glow-in-the-dark . Strontium aluminate phosphor is fired at about 1250 C. " [3] It can be synthesized by a variety of methods such as sol-gel, hydrothermal synthesis, solid-state reactions and combustion reactions. Home. 1. A tremendous potential has been observed in the designing of long afterglow materials for sensing, bioimaging, and encryption applications. Abstract.

Increased Calcium . Long lasting light but you own light may extinguish early. American Elements offers Strontium aluminate (Sr 3 Al 2 O 6) in both doped and undoped forms for phosphor lighting technology. Results show that the phase composition changes from strontium-rich phase to aluminum-rich phase with the decrease of Sr/Al: when the rate of Al/Sr changes from 3:1 . 65 Components This product does not contain any chemicals known to State of California to cause cancer, birth defects, or any other reproductive harm.

Reactivity Data: Stability: stable will not . In this study, two different strontium aluminate-based luminescent materials; SrAl2O4: Eu, Dy (S1), and Sr4Al14O25: Eu, Dy (S2) were melt-mixed with polypropylene (PP) matrix, and the phosphorescence properties were evaluated. Thus, strontium- 90 is referred to as a "bone seeker," and exposure will increase the risk for several diseases including bone cancer, cancer of the soft tissue near the bone, and leukemia. In adults, strontium mostly attaches to the surfaces of bones. The following reaction mechanism is applicable: Sr (s) + 2H 2 O (g) -> Sr (OH) 2 (aq) + H 2 (g . The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here. Subjecting it to temperatures above 1090 C is likely to cause loss of its phosphorescent properties. Relevant identified uses of the substance or mixture and uses advised against (26, 27) Strontium aluminate phosphors are harmless as defined by the Laws of Chemical Substances. Standard rare earth dopants include Europium and Dysprosium; other elements may be available by request. Strontium-90 behaves like calcium in the human body and tends to deposit in bone and blood- forming tissue (bone marrow). We also manufacture other compositions of strontium aluminates including SrAl 2 O 4 and Sr 4 Al 14 O 25. In this study, the emission intensity and luminescence lifetime of SrAl 2 O 4: Eu 2+, Dy 3+ were enhanced by partial substitution of Ca 2+ into Sr 2+ sites in the matrix. "strontium is unlikely to have a net beneficial effect in osteoporosis and its use is declining as a consequence.

Show Navigation Hide Navigation Read on to learn more about the health benefits of this mineral. A special form of strontium called strontium ranelate can increase bone formation and prevent bone loss when used in postmenopausal women with osteoporosis. Strontium reacts with water slowly, generally to strontium hydroxide and hydrogen gas. SR-ALO-02-P , SR-ALO-03-P , SR-ALO-05-P , SR-ALO-04-P CAS #: 12004-37-4 Relevant identified uses of the substance: Scientific research and development Supplier details: American Elements 10884 Weyburn Ave. Research from Europe suggests that patients on strontium ranelate may have an increased risk of heart attacks [1,3], blood clots, [1, 3] and serious skin reactions (DRESS syndrome) [3]. Strontium aluminate, europium and dysprosium doped is a luminescent compound, which can be used in persistent luminous paints, inks, and ceramics. It is made from phosphors such as Zinc Sulfide (doped with other metals to get different colors) or Strontium Aluminate (doped with Europium or Dysprosium) and typically glows a yellowish-green or blue color. The combination of strontium aluminate and europium results in the longest lasting commonly used photoluminescent phosphorescent material. Health Canada started its safety review because the risk of heart and circulatory side effects is a serious health issue, and because strontium is found in licensed natural health products as strontium salts, including strontium citrate, strontium lactate, and strontium gluconate.
