Yellow 3.4mm Synthetic Single Crystal Hpht Diamonds For Industrial
Applications
Single Crystal Hpht Diamonds Description
Lab diamonds are real diamonds. Carbon is the main element of
natural and laboratory-grown diamonds. The chemical and physical
properties of synthetic diamonds are same as natural diamonds in
terms of hardness, thermal conductivity, and strength.
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.
Diamond is the most stable material in density. Because of its
simple chemical composition and compact structure, the density of
transparent diamond has the greatest stability, and the range of
density variation is only about 0.01% when it contains impurities.
This characteristic is of special significance for gem
identification.
Diamond is the most inert material. Thermal inertia is the nature
of maintaining the thermal motion state of matter. The greater the
thermal inertia, the more difficult it is to change the thermal
state. Diamond has the highest thermal conductivity and the highest
thermal inertia, which can not be compared with any metal and
non-metallic minerals. This provides a basis for the design of
thermal test instrument. It is quick and effective to distinguish
diamond from other gemstones by thermal conductivity meter.

Synthetic HPHT Industrial Diamonds Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The Lab
Grown Diamonds are produced in the laboratory, usually in a few
weeks. The chemical difference between the two is same.
So how do you distinguish between Lab Grown Diamonds and natural
diamonds?
There is no obvious difference between the Lab Grown Diamonds and
natural diamonds. Even professional gemologists need special
equipment to identify them. By zooming in, professionals will be
able to discern subtle contrasts in diamond inclusions grown and
mined in the laboratory.
