Suitability
|
for purification, used in qualitative and
quantitative analysis of Ba2+ and SO4-2 ions, preparation of sulfur dioxide,
preparation of hybrid organic-inorganic material, used as a catalyst for the
conversion of lactic acid to acrylic acid via dehydration, it is primarily
used in oil well drilling fluid, and as filler in the paint and varnish
industry, one of the major constituents of the pigment lithiopone and the
white pigment for paints, it improves the resistance against acid and acidity
for plastics when employed as filler, further it is employed as a component
in strobe pyrotechnic compositions, and as a coating for photographic papers
to improve the effectiveness of the image, a thin layer is used to make the
papers bright for ink-jet printing, in the chemical and pharmaceutical it is
used as a catalyst support when selective hydrogenations are required, for
e.g. in Rosenmund reduction (Pd on barium sulfate), in colorimetry, is used
as a diffuser to measure light sources, in the medical field, suspension is
used clinically as a radiocontrast agent for X-ray imaging and other
diagnostic procedures, in biomaterials research, it is one of the components
utilized in the preparation of acrylic bone cements.
