In the "direct conversion" or double-decomposition method, a mixture of celesite and sodium carbonate is treated with steam to form strontium carbonate with substantial amounts of undissolved other solids. [3] This material is mixed with hydrochloric acid, which dissolves the strontium carbonate to form a solution of strontium chloride. Carbon ...

Strontium carbonate is a recycled coreactant in this process. Strontium carbonate is calcined with carbon in the presence of steam to form strontium hydroxide. The strontium and carbon dioxide formed are rejoined later in the process, forming strontium carbonate once again. [1] SrCO 3 + C + H 2 O + O 2 = Sr(OH) 2 + 2 CO 2
Strontium carbonate is used as a fire retardant in some gunpowders. Flame suppressants. Potassium nitrate and potassium sulfate are commonly used. Opacifiers. Some solid rocket propellants have problems with radiative heat transfer through the material, which may lead to explosion. Carbon black and graphite are often used to inhibit this effect.
The NFL playoff picture will soon be locked in, but teams still have an opening to make a statement. Here are our bold predictions for Week 17.
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)
