4mm*4mm Square Shape Optical Grade Single Crystal CVD Plate For Making Tools
Single Crystal CVD Plate Description
Chemical vapor deposition (CVD) is a common method for the
preparation of thin film materials. It uses the chemical reaction
of vapor precursor under specific conditions to deposit the
required thin film materials on a specific substrate. In the
preparation of large single crystal diamond materials, methane and
hydrogen are usually used as precursors to grow single crystal
diamond by vapor phase epitaxy at high temperature (about 1000 ℃),
atmospheric pressure (1 ATM) or low pressure.
All along, the preparation of diamond is an important material
science research topic. It's not just that diamonds are expensive
jewelry. The more important reason lies in the importance of
diamond in many fields, such as: diamond itself has high hardness
and high thermal conductivity, which has important industrial
application value in cutting, high pressure and other fields; The
study on the growth of diamond is helpful to the understanding of
geochemistry; Diamond color centers have potential applications in
quantum information.

Single Crystal CVD Plate 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.
