Strontium sulfate Chemical Properties,Uses,Production
Description
Strontium sulfate has the molecular formula of SrSO4
and the molecular weight of 183.6842 g/mol. It can be
prepared by the reaction of sodium sulfate and strontium
chloride:
Na2SO4+SrCl2?SrSO4+2NaCl
Strontium sulfate occurs in nature as “celestite” and is
mined from its natural deposits. Also, the sulfate can be
made by reacting strontium oxide, hydroxide, or
carbonate with dilute hydrochloric acid:
SrO+H2SO4?SrSO4+H2O
SrCO3+H2SO4?SrSO4+CO2+H2O
No hydrates are known.Its hardness is 3.3
Mohs. It melts at 1608°C. Its solubility in water is
0.015 g/100 ml at 25°C and 0.014 g at 35°C. It is insoluble
in ethanol and acetone, but slightly soluble in acids
and alkalis. It is soluble in alkali chloride solutions. The heat of formation, △Hf, is –1453 kJ/mol with an entropy
value, S0, of 117.0 J/mol K. Its Mohs Hardness is 3.0–3.5.
A water solution has a pH of 7.5. Its specific gravity ranges from 3.8 to 4.0 g/cm3.Pure strontium sulfate precipitate consists of single crystals, about
some tens of microns long, with distinctly visible growth
steps. Crystals grown with polyvinyl sulfonate in stirred
solutions show a striking change of habit: they are
sponge-like structures, composed of minute crystallites,
of size in the nanometer range.
Crystallized strontium sulfate is utilized by a small
group of protozoa as a main constituent of their skeleton.
It is sometimes used to impart iridescence to glass
and pottery glazes or used as a fining agent in crystal
glass.
There is very little demand for this salt in industry. It
is available in limited quantities commercially.

Definition
strontium sulphate: A white solid,SrSO4; r.d. 3.96; m.p. 1605°C. It canbe made by dissolving strontiumoxide, hydroxide, or carbonate in sulphuricacid. It is used as a pigment inpaints and ceramic glazes and to providea red colour in fireworks.
