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]
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 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 nitride, Sr 3 N 2, is produced by burning strontium metal in air (resulting in a mixture with strontium oxide) or in nitrogen. Like other metal nitrides, it reacts with water to give strontium hydroxide and ammonia: Sr 3 N 2 + 6 H 2 O → 3 Sr(OH) 2 + 2 NH 3
