Ultra-Large-Area Blue Diamond Materials

— A Pioneer from Materials to Energy Applications

One of the earliest teams in China to pursue the industrialization of ultra-large-area Blue Diamond (CVD diamond) materials. Applications span three major directions — thermal management, electrochemical energy, and environmental purification — covering core scenarios such as chip cooling, hydrogen energy, and disinfection.

First to Bring Blue Diamond Materials into Energy Technology

Our technological achievement has been assessed by the National Industrial Information Security Development Research Center as having "reached an internationally advanced level" (Registration No.: 3392025Y1018).

AI Computing Power Is Soaring

— Who Will Cool the Chips?

Blue Diamond heat spreaders, with thermal conductivity of 1200–2000 W/(m·K): diamond-grade thermal management, born for extreme power.

Company Profile

Guangzhou Deposon Electric Co., Ltd. is a National High-Tech Enterprise anchored in national strategic needs, with high-end diamond materials at its core. The company focuses on CVD diamond, conductive nano-diamond, and high-end BDD electrode materials, targeting frontier fields such as advanced chip thermal management, power device cooling, PEM/AEM water electrolysis for hydrogen production, and electrochemical electrodes. Deposon drives the leap of diamond from an advanced material to critical devices and major equipment, providing independently controllable core materials and technological support for the chip, new energy, hydrogen, healthcare, and environmental protection industries.

The company's core technical staff are all returnees from Germany, with long-standing expertise in diamond materials science and applied technology, combining an international outlook with deep industrialization experience.

Deposon builds its business on materials, guided by the principle of "high-end diamond materials serving critical devices." Rather than focusing on generic consumer-grade diamond products, the company is dedicated to delivering high-performance material solutions. Looking ahead, Deposon will continue to deepen its hard-tech expertise in diamond, build a world-leading platform for diamond functional materials, and become a vital innovative force supporting the nation's industrial upgrading.
