Strontium aluminate is an aluminate compound with the chemical formula SrAl 2 O 4 (sometimes written as SrO·Al 2 O 3). It is a pale yellow, monoclinic crystalline powder that is odourless and non-flammable.
LSAT is the most common name for the inorganic compound lanthanum aluminate - strontium aluminium tantalate, which has the chemical formula (LaAlO 3) 0.3 (Sr 2 TaAlO 6) 0.7 or its less common alternative: (La 0.18 Sr 0.82)(Al 0.59 Ta 0.41)O 3. LSAT is a hard, optically transparent oxide of the elements lanthanum, aluminium, strontium and tantalum.
Phosphorescent pigments performance, in visible light, in dark, after 4 minutes in dark - zinc sulfide (left) and strontium aluminate (right) based materials Super-LumiNova is a brand name under which strontium aluminate –based non- radioactive and nontoxic photoluminescent or afterglow pigments for illuminating markings on watch dials ...
Strontium aluminate is frequently used in glow in the dark toys, as it is chemically and biologically inert. [69] Strontium salts are added to fireworks in order to create red colors. Strontium carbonate and other strontium salts are added to fireworks to give a deep red colour. [70] This same effect identifies strontium cations in the flame test.
Strontium aluminate based pigments are now used in exit signs, pathway marking, and other safety related signage. [ 22 ] Zinc sulfide (left) and strontium aluminate (right), in visible light, in darkness, and after 4 minutes in the dark.
Strontium titanate single crystal substrates (5x5x0.5mm). The transparent substrate (left) is pure SrTiO 3 and the black substrate is doped with 0.5% (weight) of niobium SrTiO 3 is an excellent substrate for epitaxial growth of high-temperature superconductors and many oxide-based thin films .
The invention was patented in 1994 by Nemoto & Co., Ltd. and licensed to other manufacturers and watch brands that use different (brand) names. [2] These strontium aluminate–based phosphorescent pigments, often called lume, operate like a rechargeable light battery. After sufficient activation by sunlight, fluorescent, LED, UV (blacklight ...
Europium(II), added to strontium aluminate, used in high-performance glow in the dark materials, very long afterglow; with other host materials it is frequently used as the red emitter in color CRTs and fluorescent lights.
