About 8% by weight of cathode-ray tubes is strontium oxide, which has been the major use of strontium since 1970. [3] [4] Color televisions and other devices containing color cathode-ray tubes sold in the United States are required by law to use strontium in the faceplate to block X-ray emission (these X-ray emitting TVs are no longer in production).
Strontium peroxide is an inorganic compound with the formula Sr O 2 that exists in both anhydrous and octahydrate form, both of which are white solids. The anhydrous form adopts a structure similar to that of calcium carbide. [4] [5]
A piece of cuprate of bismuth and strontium: this piece is a cube with an edge of nearly 1 mm. Bismuth strontium calcium copper oxide (BSCCO, pronounced bisko), is a type of cuprate superconductor having the generalized chemical formula Bi 2 Sr 2 Ca n−1 Cu n O 2n+4+x, with n = 2 being the most commonly studied compound (though n = 1 and n = 3 have also received significant attention).
Strontium acetate is a compound of strontium. It is a white solid and is soluble in water like other acetates . It is used as a pathway for other chemicals such as barium acetate .
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.
Strontium carbonate is used for electronic applications. It is used for manufacturing color television receivers to absorb electrons resulting from the cathode. [5] It is used in the preparation of iridescent glass, luminous paint, strontium oxide, and strontium salts and in refining sugar and certain drugs.
Strontium oxalate can exist either in a hydrated form (SrC 2 O 4 ·nH 2 O) or as the acidic salt of strontium oxalate (SrC 2 O 4 ·mH 2 C 2 O 4 ·nH 2 O). [2] Strontium oxalate is soluble in 20 000 parts of water; in 1 900 parts of 3.5% acetic acid, in 115 parts of the 23% acid, but less soluble in the 35% acid; readily soluble in diluted HCl ...
Strontium nitrate is an inorganic compound composed of the elements strontium, nitrogen and oxygen with the formula Sr(NO 3) 2. This colorless solid is used as a red colorant and oxidizer in pyrotechnics .
