Product Description
Single crystal diamond stone HPHT Synthetic diamond plate
The synthetic single crystal diamond series are synthesized by HPHT (high pressure, high temperature) under severe growth conditions. In order to accurately synthesize large high quality crystals, it is necessary to have high purity raw materials and advanced technology for maintaining synthesizing conditions constant over a long period of time.
Single Crystal Diamond (SCD or MCD) plates, Ib type, processed from large single crystal diamonds, contain relatively large sectors substantially free of dislocations and stacking faults.

high-end applications of single crystal diamond
Diamond has many excellent physicochemical properties, high hardness, high thermal conductivity, high chemical stability, high optical transparency, wide band gap, negative electron affinity, high insulation and good Biocompatibility, etc.These unique physicochemical properties combine to make diamonds available in a wide range of applications, making diamond one of the most promising new functional materials in recent decades.However, the small amount of natural diamonds and high prices have largely restricted their market applications, so scientists are looking for artificial methods to synthesize diamonds to alleviate a large number of industrial needs. Synthetic diamond has the same structure as natural diamond and has comparable performance, while being relatively inexpensive compared to natural diamond, with a wide range of industrial applications and commercial prospects.The synthetic methods of single crystal diamond generally fall into two categories: high temperature and high pressure (HTHP) and chemical vapor deposition (CVD). The high-quality single crystal diamond prepared by the CVD method can be completely colorless and transparent, has almost no impurities, and can prepare a variety of colored diamonds if a dopant gas is selectively introduced during the growth process. Because CVD diamond has so many advantages, it will become the mainstream of future material development, and can be widely applied to key parts such as machining, communications, semiconductor, energy, defense, aerospace, military weapons and other cutting-edge fields.Ultra-precision machining
Originated in the 1950s, diamond has been successfully used as a cutting material in ultra-precision machining. Compared with polycrystalline diamond, there is no grain boundary inside single crystal diamond. The use of single crystal diamond as the tool of the cutter head can achieve atomic level flatness and sharpness; ultra-clear surface and defect-free secondary cutting edge of single crystal diamond cutter The role of the mirror can be processed to a very high degree of finish, which is currently not possible with any other material. Therefore, single crystal diamond tools have been widely used in aerospace, precision instrumentation and other fields.Optical industry
Diamond has the widest transmission spectrum in all current solid materials, from 225 nm in the ultraviolet to 25 μm in the infrared (except for the wavelengths of 1.8 μm to 2.5 μm), and in the microwave range, the diamond has excellent permeability. Due to its excellent optical properties and its high resistance to radiation damage, coupled with its high hardness, high thermal conductivity, high chemical stability and low coefficient of expansion, diamond is an ideal material for modern infrared optical windows. At the same time, MPCVD single crystal diamond can also be used as the energy input window of high-power laser devices. The high temperature resistance and thermal shock resistance of diamond can greatly improve the output power of laser devices.Particle detector
Compared with traditional silicon-based detectors, diamond detectors have the advantages of high sensitivity, low dark current, strong radiation resistance and long service life. This is because diamond has an extremely wide band gap (5.45 eV), and the C-C bond energy in the diamond lattice is very high, and the carbon atoms have a small absorption cross section of high-energy particles. When the high-energy particles pass through the single crystal diamond, the ionization of the particles forms an electron-hole pair inside the diamond crystal. When an applied electric field is applied to the diamond, the electrons and the holes move in opposite directions, respectively, to form a migration current and a migration current. The intensity is proportional to the intensity and quantity of the incident high-energy particles, and the measurement of the intensity of the incident particles is accomplished by detecting the magnitude of the migrating current.Due to the excellent characteristics of the diamond particle detector, it is particularly suitable for devices that need to detect high-energy particles, such as nuclear fusion reactors and nuclear fission reactors, space radiation detectors, and so on.Semiconductor and electronic devices
Since single crystal diamond has high electron and hole mobility, high breakdown voltage, and high thermal conductivity, it can be semiconductorized after doping, making it the most excellent wide band gap high temperature semiconductor material known at present. A mobility of up to 1150 m 2 /V has been obtained on large-sized single crystal diamond prepared by the MPCVD method. Once diamond-based high-temperature semiconductors can be applied on a large scale, the silicon-based semiconductor industry in the world will face tremendous changes. Diamond high-temperature semiconductors will lead the next semiconductor industry revolution.Gem grade diamond (synthetic diamond)
Because natural diamond is extremely rare in nature, it is basically a non-renewable resource, and at the same time it has special properties and luster, so it has been used as a high-grade ornament since ancient times. Natural diamonds are generally small and expensive, and MPCVD can be used to prepare large-grain gem-quality single crystal diamonds. The finished products obtained by polishing and polishing can be compared with natural diamonds, and their gloss and properties are even better than natural diamonds. In the process of preparing single crystal diamond by MPCVD method, if other elements are incorporated, diamonds of various colors can be produced, and the decorative effect is comparable to that of natural diamond.
