The second stage produces a dark-coloured material containing mostly strontium sulfide. This so-called "black ash" is dissolved in water and filtered. Strontium carbonate is precipitated from the strontium sulfide solution by introduction of carbon dioxide. [55] The sulfate is reduced to the sulfide by the carbothermic reduction:
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:
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 bromide is a chemical compound with a formula Sr Br 2. At room temperature it is a white, odourless, crystalline powder. At room temperature it is a white, odourless, crystalline powder. Strontium bromide imparts a bright red colour in a flame test , showing the presence of strontium ions.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
