Strontium carbonate

탄산 스트론슘 C화학적 특성, 용도, 생산

개요

Strontium carbonate has the formula of SrCO3 and the molecular weight of 147.6326 g/mol. Strontium carbonate occurs in nature as the mineral “strontianite”. The name strontianite comes from a famous location for the mineral, Strontian, Scotland. Strontianite is strontium carbonate as found naturally. It occurs as white or slightly gray orthorhombic crystals with a refractive index of 1.518. The unit-cell parameters are: a = 5.107 ? , b = 8.414 ? , c = 6.029 ? , Z = 4; V = 259.07 ? 3, Den(Calc) = 3.78. The crystal system is orthorhombic with space group Pmcn and point group 2/m, 2/m, 2/m. Strontium carbonate has only one stable form (aragonite-type structure) and temperature of precipitation has no effect on crystal form, unlike that of calcium or magnesium carbonates.

Milky white free flowing powder

용도

Used in the preparation of?iridescent glass, luminous paints, strontium oxide or strontium salts and in refining sugar and certain drugs

용도

Used for electronic applications. It is used for manufacturing CTV to absorb electrons resulting from the cathode

용도

In pyrotechnics; manufacture of iridescent glass; refining sugar.

용도

Strontium carbonate (SrCO3) is used to make radiation-resistant glass and TV picture tubes, as well as pyrotechnics.

용도

The compound, SrCO3, is used in pyrotechnics and ceramic ferrites. It is also used in making iridescent glass for color television tubes. Other uses are in refining sugar and preparing other strontium salts. The most common use is as an inexpensive fireworks colorant. Strontium and its salts emit a brilliant red color in flame. Its ability to neutralize acid is also very helpful in pyrotechnics. Another similar application is in road flares. Strontium carbonate is used for electronic applications. It is used for manufacturing glass colortelevision tubes to absorb X-rays resulting from the bombardment of the cathode rays on the glass enclosure of the cathode-ray gun. SrCO3 is used in the preparation of iridescent glass, strontium oxide or strontium salts and in refining sugar.It is widely used in the ceramics industry as an ingredient in glazes. It acts as a flux and also modifies the color of certain metallic oxides. It is also used in the manufacturing of strontium ferrites for permanent magnets that are used in loudspeakers and door-magnets. Strontium carbonate can be used to produce many different strontium compounds by simply dissolving it in the corresponding acid. Strontium bicarbonate has not been isolated.

제조 방법

Strontium carbonate occurs in nature as strontianite and can be mined from its deposit. It is, however, usually made commercially from the mineral “celestite”. Celestite is fused with sodium carbonate at elevated temperatures or boiled with a solution of

정의

strontianite: A mineral form ofstrontium carbonate, SrCO3.

정의

strontium carbonate: A whitesolid, SrCO3; orthorhombic; r.d. 3.7;decomposes at 1340°C. It occurs naturallyas the mineral strontianite andis prepared industrially by boiling celestine(strontium sulphate) with ammoniumcarbonate. It can also beprepared by passing carbon dioxideover strontium oxide or hydroxide orby passing the gas through a solutionof strontium salt. It is a phosphor,used to coat the glass of cathode-rayscreens, and is also used in the refiningof sugar, as a slagging agent incertain metal furnaces, and to providea red flame in fireworks.
