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.
A further place the strontian process came to be used was the Sugar Factory Rositz (in Rositz). [citation needed] Yet by 1883, the demand for strontianite had begun to shrink. First, it was replaced by another strontium mineral , that could be imported from England, in a cheaper way. Second, the prices for sugar decreased so much, that the ...
Strontianite (Sr C O 3) is an important raw material for the extraction of strontium. It is a rare carbonate mineral and one of only a few strontium minerals. It is a member of the aragonite group. Aragonite group members: [2] aragonite (CaCO 3), witherite (BaCO 3), strontianite (SrCO 3), cerussite (PbCO 3)
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. It is widely used in the ceramics industry as an ingredient in glazes.
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 and barium have fewer applications than the lighter alkaline earth metals. Strontium carbonate is used in the manufacturing of red fireworks. [76] Pure strontium is used in the study of neurotransmitter release in neurons. [77] [78] Radioactive strontium-90 finds some use in RTGs, [79] [80] which utilize its decay heat.

According to the manufacturer, strontium ranelate should be taken 2 hours before antacids and 2 hours apart from food, milk and derivative products, and medicinal products containing calcium. Treatment should be suspended while taking oral tetracycline and quinolone antibiotics , as these chelate the strontium ion.
