Synthetic diamond is the one produced in technological processes: from the hand of man. In the year 1797, the British chemist Smithson Tennant discovered that diamond is nothing more than a mineral composed of carbon. The possibility of imitating the crystalline form of this chemical element opens the way for the synthesis of diamond.
Synthetic diamond to the jewelry industry
In the 90s, synthetic diamond takes its first steps in the jewelry industry. The synthetic diamond sector today is very fought over by the big competitors. The estimated production of synthetic diamonds in one year is more than 3,000 million carats. That is 600 tons of synthetic diamonds. This production is higher than the 26 tons of natural diamonds that are extracted annually from mining deposits. One of the most making choices of lab grown diamond is engagement rings lab diamonds for being affordable, quality and sizes.
Synthetic diamond making procedures
With the HPHT procedure (high-pressure high-temperature), the carbon is subjected for a prolonged period to a high temperature and a strong pressure. It means that synthetic diamond is formed by germination and growth. With the HPHT colored diamonds are obtained: pink, yellow, blue and orange. In addition, with the CVD procedure, the synthesis of diamond is carried out by means of a chemical vapor deposition. This is how the artificial layers of the diamond are formed. It is then injected with methane and hydrogen, and then heated. These two processes still dominate the production of synthetic diamond, although there are other methods. Synthetic diamond is obtained by using a solution composed of 60% water and 40% ethanol.
Other characteristics of synthetic diamond
Other of its characteristics is its thermal conductivity and its electronic mobility. This is why synthetic diamonds are used in abrasives. And also as polishing and cutting tools. It is also widely used in corrosive environments due to its great resistance to acids. So its use is also frequent in electrochemistry. What’s more, when immersed in pure water, there is no chemical reaction that affects the diamond electrodes. So there are many electronic applications that use synthetic diamond due to its thermal properties. Other of its qualities is its non-toxic character and its bio-compatibility. It is also widely used in optics thanks to its transparency. Synthetic diamond has a weak electrical conductivity, a great advantage also for the semiconductor industry that uses it as well.
Know everything about the quality of lab-grown diamonds
It also happens that they are so similar that with the naked eye, it is difficult to differentiate a natural stone from a synthetic diamond. But you have to know that the properties of synthetic diamond are subject to the manufacturing process used and can be lower or higher than natural ones. The synthetic diamond has perfect qualities making it therefore very valuable in different fields. Synthetic diamond is part of an elite of hard materials obtained artificially. Thanks to its hardness, the Synthetic diamond applications are enormous.
