Synthetic Diamonds: Production

Diamonds were discovered as a component of the carbon from the year 1796 it took 150 years from then until the invention of the synthetic diamonds were created successfully. The Calendar Card as confidential by the researchers, many poor people have been released in the decade 1950's when synthetic diamonds have been synthesized by the chemical composition has been achieved in the almost simultaneous of scientists from Ames Riga and scientists. from Sweden. By using up to 55,000 atmospheres of pressure at 1400 degrees C and heating the metal in the liquid which is a necessary component in creating the conditions for the direct conversion of diamond to graphite. Currently, the production of synthetic diamonds (synthetic diamond), each year about 80 tons by General Electric, De Beers and others in the British library and other products to industrial users.

In nature, diamonds form a liquid under pressure, that deep in the earth, and it takes a long, long time in the lab to Calendar cards are two ways to cultivate a diamond in the very short. The National High Pressure-High Temperature (HPHT) diamond in the nature of the modeling process used in the laboratories of the National Chemical Vapor Decomposition (CVD) process to make the turn completely. Instead of high pressure in the CVD diamond was constructed allowing the carbon atoms are free to come together as a crystal of diamond. 


The production process of synthetic diamond CVD.
Both methods were able to cultivate a quality diamond and gemstone jewelry made quickly. CVD process, but ultimately it is going to be a tremendous benefit to the industry, new electrode technology is pretty clean, no dirt, and can control its size. Synthetic diamond (synthetic diamond) have produced a yellow diamond (yellow), blue (blue), green (green), pink (pink), red (red), purple (purple) and white, also known as a color (colorless), though. feature of almost any diamond is natural that the chemical properties (chemically) your possessions physical (physically) and optical properties (optically) synthetic diamonds can be distinguished by a jewel. trained with the tools and techniques that are commonly used in the standard can determine whether the grain any gem diamond synthesis. (As opposed to natural diamond in a diamond mine.)

  Diamond seeds, seed production in a tiny diamond CVD.
CVD process starts with a tiny diamond seed is placed in the center of the furnace atmosphere. Then release hydrogen and methane into the atmosphere of the furnace center. Liquid hydrogen as the plasma will be let go of it as a stump in the hydrogen. I do not react with methane as a matter of the matrix atoms (methyl radical) and hydrogen atoms. A group of atoms with T. This is combined with a tiny diamond seed to form a diamond growing larger.

Diamond production process, CVD is the straight line (linear process) which means that the size of the diamond production will depend on the size of grains of diamond, we entered the first time we use the Calendar Card CVD. This is a diamond in the nursery
