1.0mm To 4.0mm HPHT Lab Grown Diamonds VS SI White Diamods For Loose Diamonds

HPHT Lab Grown Diamonds 1.0mm To 4.0mm White Diamods For Loose Diamonds

Lab Grown Diamonds Product Description

Lab grown diamond is composed of 10 to 30 nm in diameter diamond crystallization aggregation of crystal diamond, more early artificial diamond with nitrogen from the air atom into diamond crystals and light syrup in color, the improved method, after scientists now the production of synthetic diamond and natural diamond without any differences in appearance, because of the different production, The molecular structure of artificial diamond is not the complete octahedral structure of natural diamond but a complex structure, which will produce phosphorescence phenomenon.

Hpht Lab Grown Diamonds Description

A very small natural diamond is placed in the center as a seed at 2300℃ at 15 to 18 atmospheres of high temperature and pressure. Around the seed diamond is a hot metal liquid, and on top of the metal solution is graphite. In this environment, the carbon atoms in the graphite will line up from the metal atoms to the diamond and form a new diamond.

High temperature and high pressure (HPHT) and chemical vapor deposition (CVD) are the two most commonly used growth methods in synthetic diamonds industrial. High temperature and high pressure exert intense heat (about 1500 degrees Celsius, or 2700 degrees Fahrenheit) and pressure (1.5 million pounds per square inch) on the diamond seed and the carbon atoms surrounding it. Chemical vapor deposition, on the other hand, uses less heat and pressure, but introduces a mixture of chemical gases, which decomposes and hardens into crystalline carbon atoms.

UPHT(Ultrahigh Pressure High Temperature): Temperature and pressure are still the two key factors in crystal manufacturing. The idea is to create diamonds in ceramic containers rather than underground. Water pressure provides high pressure, while electricity creates high temperatures, and the carbon forms crystals around a 1mm diameter seed crystal made from natural diamonds.

In the past, synthetic diamonds and processing costs are still very high, especially in the equipment, technology, process and other aspects of the requirements are still very high, but there is a small number of synthetic diamonds on the market in the world, but there is no price advantage. But with the development of technology, synthetic diamonds are now commercially viable.

Diamond has always been favored by the scientific and industrial circles, and is widely used in optics, semiconductor, oil exploration and other fields. Diamond is an excellent optical material with high transmittance from X-ray to microwave, high hardness, high thermal conductivity, high chemical stability and low coefficient of expansion. Also diamond is an ideal semiconductor material with wide band gap, high carrier mobility, high breakdown voltage and high thermal conductivity.
