Due to the characteristics of diamond, the synthesis of pure diamond is very important for many high-tech applications. It has completely changed countless industries, such as jewelry, electronics, optics, photonics, biotechnology and so on.

Some characteristics of synthetic diamond promote its demand in various industries. The unique combination of mechanical, acoustic, electrical, thermal, optical and electrochemical properties makes it have a wide range of application prospects.

According to the transparent Market Research Report, the global synthetic diamond market in 2016 was worth US $16.04 billion. It is expected to grow at a compound annual growth rate of 7% from 2017 to 2025, and is expected to reach US $29.15 billion.

Wonder Technologies LLC is a leading high-tech company specializing in the development and commercialization of CVD diamond synthesis technology, transforming the most promising basic research of Russian Academy of sciences into commercial solutions.

Main equipment and products

Advanced CVD reactor

Wt100mono, wt100poly mwcvd reactor

Designed and developed by wonder technologies, based on proprietary diamond growth technology, it is specially used for industrial production of CVD diamond and diamond materials.

Our expertise is diamond synthesis, and we know every detail of the process: how diamonds grow, all the factors that affect diamonds, plasma management and heat transfer. The new generation of WT reactors is specially developed for mass production.

Convenient and reliable design, easy operation and maintenance;

Reduce uncontrollable gas leakage;

Broad working pressure (20-500 Torr), significantly improving the growth rate of diamonds;

Full automatic control and real-time monitoring of all growth parameters;

Stable plasma under various pressure, power and substrate support geometry;

The temperature uniformity of the whole substrate support, the deviation is not more than ± 5%;

· substrate support for growing 4-inch diameter polycrystalline plates;

· "z-mover" is used for single crystal growth with a maximum movement range of 10 mm and adjustable feedback speed.

Patent technology: growth technology of high purity single crystal

The reactor can grow high-purity diamonds of the highest quality that could not be achieved before, and has unique electronic, optical, thermal and mechanical properties. The stability of synthesis conditions can be guaranteed for hundreds of hours.

1. Polycrystal

Products:

Up to 4 inches in diameter

Depending on the material quality, the growth rate can reach 2-10 μ M / h

Microcrystalline sizes from nanodiamond to microdiamond

Application scope:

Radiation and chemical protective coatings

Heat dissipation of electronic equipment

Blade and coating of cutting tools

Visible and infrared windows

2. Single crystal

Products:

15-25 crystals were deposited in one growth process

Growth rate: 20 μ M / h

Size up to 10 * 10 * 5mm (4-8 carats)

3. Doped diamond

The formation of point impurity defects in diamond can be doped. In the growth process, the impurity gas ensures the uniform distribution of color centers at a given concentration and high luminous intensity. Doped diamond materials can be used in fluorescent labeling or quantum optical technology.

Doping gases: N2, b2h6or B (CH3) 3, SiH4, geh4

Impurity centers in Diamond: NV, H3, N3, etc.; B; SIV; GeV
