Strontium oxide or strontia, SrO, is formed when strontium reacts with oxygen. Burning strontium in air results in a mixture of strontium oxide and strontium nitride. It also forms from the decomposition of strontium carbonate SrCO 3. It is a strongly basic oxide.
Besides the simple oxide SrO, the peroxide SrO 2 can be made by direct oxidation of strontium metal under a high pressure of oxygen, and there is some evidence for a yellow superoxide Sr(O 2) 2. [13] Strontium hydroxide , Sr(OH) 2 , is a strong base, though it is not as strong as the hydroxides of barium or the alkali metals. [ 14 ]
Strontium titanate is an oxide of strontium and titanium with the chemical formula Sr Ti O 3. At room temperature, it is a centrosymmetric paraelectric material with a perovskite structure.
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 .
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]
Distrontium ruthenate, also known as strontium ruthenate, is an oxide of strontium and ruthenium with the chemical formula Sr 2 RuO 4. It was the first reported perovskite superconductor that did not contain copper .
Strontium oxalate is a good agent for use in pyrotechnics since it decomposes readily with the addition of heat. When it decomposes into strontium oxide , it produces a red flame color . Since this reaction produces carbon monoxide , which can undergo a further reduction with magnesium oxide , strontium oxalate is an excellent red flame color ...
Strontium hydroxide, Sr(OH) 2, is a caustic alkali composed of one strontium ion and two hydroxide ions. It is synthesized by combining a strontium salt with a strong base . Sr(OH) 2 exists in anhydrous , monohydrate , or octahydrate form.
