CVD Single Crystal Diamond

Scio Diamond Technology Corporation (OTC-BB: SCIO.OB) announced today that results from their first low-level growth runs have created in excess of 50 gross carats of useable single crystal CVD diamond.   Scio has brought to life seven reactors thus far.  All 10 initial reactors are to be in full production during their second quarter.
 
Joe Lancia, Scio Diamond's CEO said, "After meticulous testing and phased startup we have made our first S3532 technology production run and received a positive result.  The output of this run gives us material for our self-sustaining seed process, as well as the ability to supply our clients' material to begin their own testing.  This is an exciting time."
Scio is beginning to take orders and complete production plans for the next 12 months.  Quantities of gross diamond will be increasing on a regular basis, as Scio completes and comes to full production on it S3532 technology and transitions to its S3724 technology.  "The S3724 technology has the potential to increase the S3532 technology by over 50%," says Lancia.
As the first seven reactors complete production testing and have entered into the first phase of production, the last three reactors are being readied to start their startup testing in a few short weeks.  Their startup is inclusive of the rigorous levels of testing of the previous seven.  This continues our completion of successful milestones to initiate and build production during its fiscal first quarter ending June 30 and to phase into full production during the following quarter ending September 30.
About SCIO Diamond
Scio Diamond will employ a patent-protected chemical vapor depositionprocess to produce high-quality, single-crystal diamonds in a controlled laboratory setting, with such diamonds referred to as "lab-grown" or cultivated diamonds. The diamonds are intended to have the identical chemical, physical and optical properties as diamonds found in the earth, and the company's highly controlled manufacturing process will enable it to produce very high-quality, high-purity, high volume, single-crystal colorless, near colorless and fancy colored diamonds.
Scio's technology will permit it to produce lab-grown diamond in size, color, and quality combinations that are very rare in nature. SCIO intends to offer diamonds in limited quantities as jewelry and in the technology arena as the material operating system of the future.

  1. What are Synthetic Diamonds?



    Synthetic diamonds are sometimes referred to as laboratory-created diamonds, laboratory-grown diamonds, or cultured diamonds, and are manufactured diamond crystals produced by man, not nature.

    Synthetic diamond can be optically and chemically identical to natural diamond.
    Gem-quality synthetic diamonds are predominantly cubic and octahedral in the rough form. Impurities are common, but as the technology has progressed so the rough diamond crystals have improved. A diamond's hardness can vary depending on its impurities and crystalline structure.

    Although synthetic diamonds have similar structure and chemical properties to a natural diamond, they can be conclusively identified by differences in atomic structure and trace impurities due to their different growth environment.

    Colour zoning, inclusions, fluorescence and other properties of synthetic diamonds provide practical visual indicators using standard gemmological techniques and equipment, but conclusive identification requires advanced equipment and trained technicians in a laboratory.

    Synthetic diamonds can sell at a fraction of the cost of natural diamonds, because they are made for less than it costs to mine a natural diamond. For this reason they are a viable alternative to natural diamond or less durable simulants.

    DCLA does not certify synthetic diamonds, but laboratories that do opt to certify synthetic diamonds must clearly state on the certificate that the diamond is a laboratory-created, synthetic diamond.

    There are currently two known processes for growing synthetic gem-quality diamonds: the High Pressure High Temperature (HPHT) method, and the Chemical Vapour Deposition (CVD) method.


    The High Pressure High Temperature (HPHT) method to produce synthetic diamonds uses large presses that can weigh several hundred tons and enormous heat to reproduce the conditions that created natural diamonds. Diamond growth occurs when a form of carbon, graphite, is subjected to this high heat and diamond stabilising pressures in the presence of a metal for a certain period of time. The metal acts as a solvent for the graphite, and also acts as a catalyst to enable crystal growth.

    To create coloured HPHT synthetic diamonds, the as-grown diamond crystal may be treated with various methods to induce a colour change, just as natural diamonds are colour treated.

    The second method, using Chemical Vapour Deposition or CVD, is very much like the process of creating frost on a window pane, when water molecules condense from the air and create a layer of frost. Diamond crystals are formed from a carbon-containing gas without the use of pressure.

    The CVD method for growing synthetic diamonds was invented in the 1980s, and involves mixing gases (typically methane and hydrogen) in a vacuum chamber. When heat is applied inside the chamber, chemical reactions of the gas mixture deposit synthetic diamond onto a diamond substrate.
