Single-Crystal vs Polycrystalline CVD Diamond: Process Difference Lies in Growth Logic, Not Equipment

The process difference between singlecrystal and polycrystalline CVD diamond lies not in equipment, but in growth logic. Singlecrystal and polycrystalline CVD diamond are two functional new materials with completely independent growth mechanisms, lattice structures and performance systems. Their process logic, product features and application boundaries diverge fundamentally from the very start of deposition and growth. Comparing or selecting materials without considering their underlying crys

From Lab-Grown Diamonds to Industrial Diamonds: Is It Time to Build an MPCVD Factory?

The lab-grown diamond industry is entering a new stage. Over the these few years, lab-grown diamonds have gradually gained wider acceptance in the jewelry market. With the development of production technology, equipment maturity and supply chain improvement, the industry is becoming more standardized and efficient. But beyond jewelry, another opportunity is attracting more attention:Industrial diamond applications.

Diamond‑Copper Composite: A Next‑Generation Solution for High‑Power Electronics Thermal Management

Diamond‑copper composite (DC) is an advanced metal‑matrix composite material consisting of diamond particles as the reinforcement phase and copper as the matrix, fabricated through state‑of‑the‑art composite preparation techniques. Diamond has the highest thermal conductivity of any naturally occurring material, with isotropic values ranging from 1200 to 2300 W/m·K. Copper, with a thermal conductivity of 401 W/m·K, ranks second only to silver among common metals. By combining the two, the compo

Mosaic Single‑Crystal Diamond: Breaking Size Limits

With an ultra‑wide bandgap of 5.47 eV, ultra‑high thermal conductivity (>2000 W/m·K), high carrier mobility (electron mobility up to 4500 cm²·V⁻¹·s⁻¹), and ultra‑high theoretical breakdown field strength (>10 MV/cm), Single‑Crystal Diamond (SCD) is an ideal candidate for next‑generation high‑power, high‑frequency and extreme‑environment electronic devices. However, both natural diamond and HPHT‑synthesized single‑crystal diamond are limited in lateral size, which greatly hinders large‑scal
