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.
Strontium carbonate is also used for making some superconductors such as BSCCO and also for electroluminescent materials where it is first calcined into SrO and then mixed with sulfur to make SrS:x where x is typically europium. [citation needed] This is the "blue/green" phosphor which is sensitive to frequency and changes from lime green to blue.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
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.

In New York, more than 1.8 million adults, or 11.7% of the state's adult population, have been diagnosed with diabetes, according to the American Diabetes Association. An additional 92,000 are ...
"American Nightmare" victims Denise Huskins and Aaron Quinn worked with two small-town law enforcement officials to get kidnapper Matthew Muller to confess to more cold case crimes.
Solubility constants are used to describe saturated solutions of ionic compounds of relatively low solubility (see solubility equilibrium). The solubility constant is a special case of an equilibrium constant. Since it is a product of ion concentrations in equilibrium, it is also known as the solubility product. It describes the balance between ...
