BARITE PREVENTS BLOWOUTS, ABSORBS NUCLEAR EMISSION.
By: Jum’an
Bentonite clay as I wrote in my
previous blog, has various uses and applications due to its unique
swelling ability, colloidal size particles and thyxotrophic properties. Every mineral
have their own specifics that renders their own field of applications. Barite
or barium sulphate- has unique properties that define a wide range of
industrial uses. It has high specific gravity, chemically inert and insoluble,
low hardness (not abrasive) and ability to absorb X-rays. As a non metallic
mineral, a density of 4, 2-4.5 g/cm3 is exceptional. These characteristics have
made barite suitable for a wide range of industrial, medical and manufacturing applications.
About 80% world production of barite is used as
weighting material in the formulation of drilling fluids. Barite
increases the hydrostatic pressure of the drilling fluids allowing it to
compensate for high-pressure zones experienced during drilling and prevent blowouts. The softness of
barite (3-3.5 on Moh's scale) makes it less abrasive and less damaging drilling
tools during drilling. Another benefit of
barite is that it is non-magnetic and thus does not interfere with magnetic
measurements taken in the borehole. Substitutes for barite in
drilling fluids include: ilmenite, hematite and galena. But none of these
substitutes is effective at replacing barite in the market. They are too
expensive or do not perform competitively. Specifications of barite for
drilling mud purposes are established by the American Petroleum Institute (API).

Another unique feature of barite is its ability to
strongly absorb X-rays and gamma rays. It is applied in diagnostic medical
tests on the intestines and colon. If a patient drinks a small cup of liquid
containing barite powder in a milkshake consistency (barium meal), the liquid
will coat the patient's esophagus. An x-ray of the throat taken immediately
after the "barium swallow" will image the soft tissue of the
esophagus (which is usually transparent to x-rays) because the barium is opaque
to x-rays and blocks their passage. This ability to absorb X-rays, barite is also
used to make high-density concrete to block x-ray emissions in hospitals, power
plants, laboratories and nuclear reactors. In addition, barite is the cheapest
protective material in the construction of "burial grounds" and
reactors in nuclear power industry.
Nuclear Waste Burial
Additional uses of barite
include as filler in the manufacture of linoleum, oilcloth, paper and textile
manufacturing, rubber, and plastics, brake linings, paint and sound-deadening
material in cars. For those who love crystal
healing, barite
crystal is said as excellent in balancing the brain chemistry, assists
with memory and information retention. It strengthens inner vision and is a
strong stone to enhance dream recall.
