The KINTEK MPCVD Advantage: Superior Diamond Synthesis
KINTEK's MPCVD technology offers significant advantages for diamond synthesis compared to other methods like HFCVD (Hot Filament CVD) and DC-PJ CVD (Direct Current Plasma Jet CVD):
- High Purity Diamonds: MPCVD avoids diamond contamination from elements like hot wires (as in HFCVD). In our system, the plasma ball doesn't contact the cavity wall, ensuring an impurity-free growth process and leading to diamonds of higher purity compared to those from the HPHT (High-Pressure High-Temperature) method.
- Versatile Gas Use: Allows the use of multiple gases (e.g., CH4, H2, Ar, O2, N2) to meet diverse industrial needs and tailor diamond properties.
- Stable & Precise Control: Enables smooth, continuous adjustment of microwave power and stable control of reaction temperature. This avoids issues like crystal seeds falling off the substrate due to arcing and flame failure sometimes seen in DC-PJ CVD. The substrate temperature is precisely controlled by the plasma position and measured by a thermocouple.
- Large Area Stable Plasma: The MPCVD method generates a large area of stable discharge plasma, making it the most promising diamond synthesis method for industrial applications and scaling up production.
- Energy Efficient & Cost-Effective for Larger Diamonds: The MPCVD production process typically consumes less energy than HPHT and facilitates the production of larger, high-quality diamonds at a potentially lower cost.

Working Principle: How KINTEK MPCVD Grows Diamonds
The KINTEK MPCVD machine meticulously controls the growth environment. The process begins by controlling the flow of each gas path (reactant gases such as CH4, H2, Ar, O2, N2, etc.) and cavity pressure, introducing these gases into the cavity under specific, stabilized conditions. Once airflow is stable, the 6KW (or adjustable 1-10KW) solid-state microwave generator generates microwaves, which are then introduced into the cavity through a waveguide.
Under the microwave field, the reaction gas transforms into a plasma state, forming a plasma ball that hovers above the diamond substrate. The high temperature of the plasma heats the substrate to the specific temperature required for diamond growth. Excess heat produced in the cavity is efficiently dissipated by the water cooling unit.
To ensure optimal growth conditions during the MPCVD single crystal diamond growth process, factors such as microwave power, gas source composition, and cavity pressure are precisely adjusted. The non-contact nature of the plasma ball with the cavity wall is crucial, as it prevents impurities from contaminating the diamond growth process, thereby enhancing the final quality of the diamond.
Applications of Diamonds Grown with KINTEK MPCVD
Diamond's unique properties—including its extreme hardness, stiffness, high thermal conductivity, low thermal expansion, radiation-hardness, and chemical inertness—make it a highly valuable material. While natural and HPHT diamonds have faced limitations due to cost, size, and impurity control, KINTEK's MPCVD technology opens doors for broader applications:
- Gemstone Quality Diamonds: MPCVD is a primary equipment used for growing diamond gemstones, offering a promising route to producing low-cost, high-quality large diamonds for the expanding jewelry market.
- Semiconductor Industry: Diamond film growth can be either monocrystal or polycrystalline. It is extensively used for large-size diamond substrates in the semiconductor industry.
- Cutting & Drilling Tools: The exceptional hardness of MPCVD diamonds makes them ideal for the diamond cutting or drilling tools industry.
- Optics and Advanced Materials: For applications leveraging diamond's unique optical and thermal properties.
Compared to the HPHT method for lab-grown diamonds, the microwave CVD method, as employed by KINTEK, is advantageous for large-sized diamond growth at a lower cost. This makes it an ideal solution for applications in semiconductor diamonds, optics diamond growth, and meeting the needs of the large jewelry diamond market.
