Answer:
Synthetic diamond is a human-made diamond which has same chemical composition, crystal structure, and physical characteristics as a natural diamond. It has some characteristics. First, it can be made to the exact size. Second, it is flawless and harder than natural diamond. It also hard to visually distinguish from natural diamond and cheaper than natural diamond. Last, it is colorful and small than natural diamond. The synthetic diamond is made by high pressure and high temperature.
It use a tiny diamond for a seed which placed in the container with graphite and special liquid solution. And then, closed the container and placed under intense heat and pressure. Pressure enables graphite to separate into individual atoms. Then, atoms attach to the diamond seed and grow. After a few days, it will be done.
Synthetic diamond is a human made reproduction that consists of same chemical composition, crystal structure, and physical characteristics as a natural diamond. Synthetics are flawless. Because flaws affect hardness, synthetics are harder than natural diamonds and better in tools. I tis also hard to distinguish synthetic from natural diamonds. Synthetic diamonds are more pure and they are not as large as natural ones. It is made in a special container. First of all, seed is placed with graphite and special liquid solution. Secondly, container is closed, placed under intense heat and pressure. Pressure enables graphite to separate into individual atoms and atoms attach to the diamond seed and grow and this procedure takes only a few days.

ReplyDeleteSynthetic diamond is human-made reproduction. It has the same chemical composition, crystal structures, and physical characteristics as a natural diamond. Synthetics are flawless, harder, cheaper, and pure than natural diamonds. They contain some metals, otherwise, same with natural diamonds. Their color can be reproduced, and sizes are not as large as natural ones.
ReplyDeleteThe method of make synthetic is put seed into a special container, then placing the seed with graphite, special liquid solution. Next, close the container and place it under intense heat and pressure. A few days later the synthetic diamond would be made.
Answer A
ReplyDeleteThe synthetic diamond is human-made reproduction, same chemical composition, crystal structure, and physical characteristics as a natural diamond. Its characteristics are flawless, hardness, more pure and more available colors, not as large as natural ones, so not as good for jewelry. The process of made the synthetic diamond are mining, construction, and electronics. Also used for machine tools, cutting tools. It can be made to the exact size needed in industry.
Synthetic diamond is a human-made reproduction; same chemical composition, crystal structure, and physical characteristics as a natural diamond. Synthetic diamond is harder than a natural diamonds, and nearly 95% of synthetic diamond are used as a tool in industry. Another reason why it can be used in industry is it can made in exact size and cheaper than a real diamond by 30%. Moreover, there is a great demand for synthetic diamond, especially for high-tech industries. In addition, synthetic diamond with some metals is more pure, more colorful than a natural one.
ReplyDeleteMost common way to create synthetic diamonds- high pressure, high temperature. First, put seed, graphite and solution in a container. After close the container, place it under intense heat and pressure. The procedure takes only a few days, then we can get a synthetic diamond.

Synthetic diamond is the human-made reproduction.There is no different in chemical composition ,crystal structure and physical characteristics between Synthetic diamond and Natural diamond. But Synthetic diamonds are flawless which are header ,cheaper and more pure than natural ones ,especially they can be reproduced unique colors,however natural ones can't .They also play a key role industries but,Synthetic ones aren't as large as natural ones ,so not as value for jewelry.
The fundamental method to make Synthetic diamonds is "HTHP" .Firstly,put seed into the container then placing the seed with graphite,after that close the container and place it under high heated and pressure.Finally,just a few days later,Synthtic diamonds can be produced .

DeleteSynthetic diamond is one of human reproduction,which contains the same elements with natural ones except some metals and available in some different colors. Comparing with the natural one,synthetic diamond is smaller and cheaper but more pure and hard.So they are better used in tool and high-tech industries and hard to be distinguished. Synthetic diamond can be made by HPHT-high pressure and high temperature.After putting seed into a container with graphite, special and liquid solution, make sure graphite can be separated into individual atoms by pressure.You will get a synthetic diamond after a few days.
ReplyDeleteSynthetic diamonds are human-made reproductions which constitute by some chemical in crystal structure. Basically, its physical characteristics are similar with nature diamonds. In general, synthetic diamonds are made in exact size for industry use; however, they are not as large as nature diamond. Moreover, synthetic diamonds are flawless, so it is harder than nature ones. It is difficult to visually distinguish synthetic diamonds from nature ones. In substance, synthetic diamonds contain the same elements as natural ones, except some metals. Furthermore, synthetic diamonds are more pure and have more color options than nature ones. The most common way to create synthetic diamonds is high pressure, high temperature (HPHT). Scientists put the seed into special container and add special liquid solution. Closing container, then place it under intense heat and pressure. Graphite will separate into individual atom by pressure. Atoms start to grow up. All procedure takes only few days.
ReplyDeleteSynthetic diamond is a diamond reproduction which is made by human. It has same chemical organization, crystal construction, and physical characteristics as a natural diamond. Synthetic diamond is cheaper, more pure, harder than natural one. Thus, synthetic diamond is flawless. Also synthetic diamond contains some metals, otherwise, it is same. In addition, synthetics diamond looks so similar to natural diamond, so it is hard to visually distinguish between them.
ReplyDeleteIt is made from special container with seed, graphite, and solution inside. Next, container is closed, and placed under intense heat and pressure. After that, make sure graphite to separate into individual atoms, then leave it for a few days. Synthetic diamond would be made it through these process.
Synthetic diamonds which is literally means fake diamonds. This is a fake diamond because it is a man kind made diamond. It is made scientifically by the scientist. They used the same principle from the natural diamond. Generally, synthetic diamonds are made for industrial purposes therefore they are made in exact same size. With today’s technology, it is almost impossible to make a diamond as big as natural ones but the good part of the synthetic diamonds are that it is flawless, therefore it is more solid than the natural ones. It is very hard to distinguish a synthetic diamond to natural diamond that is because synthetic diamonds has exact substances and made in a same principle to natural diamonds. Another advantages for fake diamonds are that they have more color options and more pure than the natural ones. The main principle of this diamonds are made is HPHT method, high pressure and high temperature. Scientists put the seed into special container and add liquid solution. After all the elements are contained, they close it and place it under intense heat and pressure. If these steps are safely done, graphite has to be separated into individual atoms by its pressure. Finally, the atoms will be grown and then it will take few days to finish all this procedures.
