STRONTIUM CHLORIDE

STRONTIUM CHLORIDE is a salt of strontium and chloride, which helps to reduce the tooth sensitivity by forming a barrier over microscopic tubules in the dentin-containing nerve endings exposed by gum recession. 

However, STRONTIUM CHLORIDE barrier protection for tooth hypersensitivity has been superseded by other toothpaste formulations and ingredients designed to be nerve-calming agents instead. 

STRONTIUM CHLORIDE (SCI2) is a salt of strontium and chloride, which can be prepared by treating strontium hydroxide or strontium carbonate with hydrochloric acid. 

STRONTIUM CHLORIDE is an antibacterial drug. 

STRONTIUM CHLORIDE strengthens the teeth and decreases the effects of acid and bacteria on the teeth. 

STRONTIUM CHLORIDE facilitates the teeth' natural repair process and prevents the growth of dental cavities. 

Like all compounds of Sr, this salt emits a bright red color in a flame and is used as a source of redness in fireworks.

STRONTIUM CHLORIDE hexahydrate (SrCl2·6H2O) catalyzes gem-dihydro peroxides (DHPs) from aldehydes or ketones.

STRONTIUM CHLORIDE is a catalyst for converting ketones and aldehydes to the corresponding gem-hydroperoxides using aqueous hydrogen peroxide.

It may be used for the preparation of SrCl2·2H2O.

STRONTIUM CHLORIDE hexahydrate is a precursor to preparing strontium chromate, a corrosion inhibitor for aluminum. 

STRONTIUM CHLORIDE is involved in the synthesis of cadmium sulfide core photocatalytic nanoparticles. 

STRONTIUM CHLORIDE is used as a red coloring agent in pyrotechnics. 

Furthermore, it is utilized in glass-making and metallurgy. 

Its radioactive isotope, strontium-89, is used in the medical field to treat bone cancer.

STRONTIUM CHLORIDE (SrCl2) is a salt of strontium and chloride. 

Strontium Chloride is a 'typical' salt, forming neutral aqueous solutions. 

As with all compounds of strontium, this salt emits a bright red color in flame and is commonly used in fireworks to that effect. 

Its properties are intermediate between barium chloride, which is more toxic, and calcium chloride.

Preparation

STRONTIUM CHLORIDE can be prepared by treating aqueous strontium hydroxide or strontium carbonate with hydrochloric acid:

Sr(OH)2 + 2 HCl → SrCl2 + 2 H2O

Crystallization from cold aqueous solution gives the hexahydrate, SrCl2·6H2O. 

Dehydration of this salt occurs in stages, commencing above 61 °C (142 °F). 

Full dehydration occurs at 320 °C (608 °F).[2]

Uses

STRONTIUM CHLORIDE is a precursor to other compounds such as yellow strontium chromate, strontium carbonate, and strontium sulfate. Exposure of aqueous solutions of STRONTIUM CHLORIDE to the sodium salt of the desired anion often leads to the formation of the solid precipitate:

SrCl2 + Na2CrO4 → SrCrO4 + 2 NaCl

SrCl2 + Na2CO3 → SrCO3 + 2 NaCl

SrCl2 + Na2SO4 → SrSO4 + 2 NaCl

STRONTIUM CHLORIDE is often used as a red coloring agent in pyrotechnics. 

Strontium Chloride imparts a much more intense red color to the flames than most alternatives. 

Strontium Chloride is employed in small quantities in glass-making and metallurgy. 

The radioactive isotope strontium-89, used for treating bone cancer, is usually administered as STRONTIUM CHLORIDE. 

Seawater aquaria require small amounts of strontium chloride, consumed during the growth of certain plankton.

Dental care

Strontium Chloride helps reduce tooth sensitivity by forming a barrier over microscopic tubules in the dentin-containing nerve endings exposed by gum recession. 

Known in the U.S. as Elecol and Sensodyne, these products are called "STRONTIUM CHLORIDE toothpaste," although most now use saltpeter (KNO3) instead, which works as an analgesic rather than a barrier.

Biological research

Brief STRONTIUM CHLORIDE exposure induces parthenogenetic activation of oocytes, which is used in developmental biological research.

Soil testing

STRONTIUM CHLORIDE is used with citric acid in soil testing as a universal extractant of plant nutrients.
