Important uses of diamonds that we did not think of
Important uses of diamonds that we did not think of
Most of us think of a diamond as an expensive gem that is used
in jewelry; a
gem that enhances the beauty of a lady's finger or her neckline.
Not many
can think of this brilliant piece as an essential part of
machinery. The two
aspects of this gem are so diverse in association and nature
that one doesnot really associate the two uses with each other.
The diamond has certain very unique properties that enable it to
be used in
these various applications. It is the hardest substance on
earth, has an
extremely high thermal conductivity, is optically transparent
and has high
electrical resistance.
The hardness property of the diamond makes it amenable to be
used as a
cutting tool, especially for hard substances like marble,
granite and hard
wood. It is embedded in mechanical tools to enable the shaping
of engine
blocks and automotive components.
Once the process of developing synthetic diamonds was
discovered, these
synthetic diamonds were obviously the most preferred option for
use in
machinery. Other than the cost, there are other advantages of
usingsynthetic diamonds in tools. The growth of the synthetic
diamond can be
monitored, controlled and the diamond can be shaped in the
manner
desired.
This is not the case with respect to natural diamonds where
nature
determines the shape, size and contours of the diamond based on
various
random natural events. Since the development of the synthetic
diamond
takes place in a laboratory, the level of impurities and mineral
inclusions can
be controlled. Due to these reasons and more the synthetic
diamond today
is sturdier as compared to the natural ones.
Another property that lends itself to use in mechanical work is
that of
thermal conductivity. The type IIa diamond can conduct up to 5
times more
heat than the metal copper. The fact that it can absorb high
levels of heat
means that it can be used to reduce the friction in many
engineering parts.Including the diamond as a 'heat sink' helps in
extending the life of the
machinery since it avoids wear and tear due to friction and
heat. 'Slices' of
synthetic diamonds are also be used for other industrial and
surgical tools.
Much research is being done to use diamond chips instead of
silicon chips
in computers and it is being said that such computers would be
1000 times
faster than the existing ones.
Even though the diamonds were being produced synthetically in
the early
1990's, they had not made their appearance in the jewelry
industry. Large
synthetic diamonds could be used only by using a lot of energy
and ultra-
modern technology. Since the engineering and mechanical market
needs
were yet not being met completely by the synthetic diamond
supply, the
proliferation of the synthetic diamond in the jewelry industry
was abated.
Another reason why the synthetic diamonds did not make their way
into the
studded necklaces was the fact that most of the synthetic
diamonds being
produced were still yellow or brownish in color.
The development and growth process of large diamonds required
for the
tools industry itself took too long. In 1990, De Beers claimed
to have
produced the largest synthetic diamond; a yellowish brown piece
that was
about 14.20 carats. This diamond alone took 500 hours to grow.
Three
years later they reported having produced a 34.80 carat crystal
that took
600 hours to grow. Another few years and De Beers claimed that
it was
possible to produce 30 carat crystals in lesser time. But now
one can find
synthetic diamonds in many fancy colours and in white colorless
shades
too.

Even though there were great obstacles in perfecting the art of
making gem
quality synthetic diamonds, some companies forged ahead and
continued to
research the process. The challenge that they faced was that
they could not
keep nitrogen out of the process of production, the gas that
gave the
diamonds the yellow color.
GE was the first company to produce an almost colorless
synthetic diamond
by eliminating nitrogen from the process. This was done by using
a metal
flux, a substance that melts and dissolves other material in it.
Special
compounds were added to the metal flux to keep the nitrogen from
entering
the process chambers. Even though De Beers had also discovered
the artof making synthetic colorless diamonds, neither company
released their
experiments and the colorless gems that came from them into the
market.
However, a Thai-Russian joint venture in Thailand distributed
synthetic
colorless diamonds into the market.
Since the jewelry market does not require large pieces, these
colorless
synthetics are faster to grow, produce and sell in the market.
Though the
synthetic diamonds gives a larger audience to the jewelry
designers, they
increase the possibility of being swindled, fraud and
non-disclosure. As the
production process is perfected and better quality colorless
synthetics are
produced and marketed each year, the challenge for the
professionals in
the jewelry industry becomes harder.
