Hpht Single Crystal 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 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.
