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.
