Synthetic Diamond, CVD Diamond, Man-made diamond
The process of CVD diamond makes it more easily treated and useful and the carbon content within the diamond is as similar as the real one and lustrous as well. The term CVD means Chemical vapour decomposition where the graphite is used as the agent which is then mixed to combine with the gas of hydrocarbon where the content of the hydrogen is

Diamond Materials - Properties of CVD Diamond
The most important properties of CVD diamond are the unsurpassed hardness, the extremely high thermal conductivity (>1800 W/mK, five times that of copper) and the broad band optical transparency. We have summarized the main properties of CVD diamond in our "CVD diamond booklet".
CVD(Chemical Vapor Deposition) Synthetic Diamonds For Sale
CVD (Chemical Vapor Deposition) diamond. The mixture of carbon-containing gas and oxygen is excited and decomposed at a high temperature and a pressure lower than the standard atmospheric pressure to form an active diamond carbon atom, and the deposit is alternately grown on the substrate to form a polycrystalline diamond.

Observations on CVD-Grown Synthetic Diamonds: A Review
Many of these samples have been described in detail in previous articles (Wang et al., 2003, 2007, 2010, 2012) and in G&G’s Lab Notes section (e.g., Wang and Moses, 2008; Wang and Moe, 2010; Ardon et al., 2013; Wang et al., 2013; Ardon and Wang, 2014; Moe et al., 2014).Whereas earlier studies examined small batches of CVD synthetic diamonds from specific manufacturers, which were likely to
Synthetic diamond (also known as laboratory-grown diamond, laboratory-created diamond, or cultured diamond) is diamond produced by a controlled process, as contrasted with natural diamond created by geological processes or imitation diamond made of non-diamond material that appears similar to diamond. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, after the two common
CVD Diamond - FAQ
For diamond CVD a carbon containing gas is decomposed and the carbon atoms are deposited on a surface. By proper conditions the growth of diamond crystals can be enhanced and the growth of graphite is suppressed. How does it work ? For diamond CVD atomic hydrogen plays a key role. It is obtained by dissociating hydrogen molecules (H2).
CVD-Grown Synthetic Diamonds, Part 1: History
CVD synthetics are cut and polished in the same manner as natural diamonds, at the same cost. The stones can be laser inscribed on the girdle to allow easy preliminary identification. Figure 2 shows typical CVD-grown cut and polished synthetic diamonds. In the next installment of this series, we will look at the properties of CVD synthetic
How are Natural Diamonds Formed? | Forevermark
CVD, the more commonly used process, again starts with diamond seeds. These seeds are exposed to a gas mixture that is heated to a temperature of around 3000°C in a sealed chamber. The gases then form a plasma and carbon atoms are able to stick to the diamond seed and then crystalise to form a larger diamond.

Is the use of cholesterol in mortality risk algorithms
Table 1 shows the sex‐specific associations of different levels of serum cholesterol with mortality, both total mortality and CVD and IHD mortality. Among women, serum cholesterol had an inverse association with all‐cause mortality as well as CVD mortality (although not reaching statistical significance) ().The association with IHD mortality appeared to follow a U‐shaped curve.

Carbonado: Physical and chemical properties, a critical
An important aspect of the model is that the process is akin to the formation of diamonds by CVD at plasma temperatures and low pressures, insofar as both CVD and stellar atmospheres have approximately similar H/C and C/O ratios; if C/O > 1 carbon is thermally condensed directly to diamond (Clayton, 1989), the CVD analogy is perfectly
