用途主たる用途は他のストロンチウム化合物の製造における中間体である〔ULLMANNS(E) (2003)〕。

説明Strontium chloride is the inorganic salt consisting of strontium and chloride. In organic synthesis, it can be used as the resource for the manufacturing of other kinds of strontium compound. Compared with the sulfide, it has the advantage of not reacting with oxygen and carbon dioxide, which facilitates industrial handling. Strontium chloride hexahydrate is used in toothpastes for sensitive teeth.It can also be used to reduce the tooth sensitivity through covering the microscopic tubules in the dentin with nerve endings which has been exposed to gum recession. It can be further used as a red coloring agent in pyrotechnics. Recent study has also shown that a novel topical formulation containing strontium chloride can effectively reduce the intensity and duration of cowhage-induced itch. In biological research, it has been successfully used to induce activation of mouse oocytes in nuclear transfer and other experiments, which is important in understanding the mechanisms of fertilization and early embryonic development. Strontium chloride is not classified as a dangerous material in transport regulations.

使用Strontium chloride are white needles made by fusing calcium chloride with sodium carbonate. It is soluble in water and alcohol. Strontium chloride was a popular halide for making collodion-chloride printing-out emulsions.

一般的な説明Strontium chloride hexahydrate (SrCl2·6H2O) is a hydrated alkaline earth metal chloride. On γ-irradiation at 77°K, it affords a radical having e.s.r. parameters resembling with HO2. Its chlorine electric field gradient (EFG) and chemical shift (CS) tensors have been evaluated by employing solid-state 35/37Cl NMR spectroscopy.

製造方法Strontium chloride is obtained by dissolving strontium carbonate in concentrated hydrochloric acid. The hexahydrate, SrCl2 · 6H2O [10025-70-4], is formed on crystallizing below 61℃. On dehydration, the hexahydrate dissolves in its water of crystallization at 61℃. After passing through the di- and monohydrate stages, strontium chloride becomes fully dehydrated at 320℃.
