What is synthetic diamond powder used for?

Supreme Abrasives' synthetic diamond powder is essential for precision grinding, lapping, and polishing of hard materials like tungsten carbide, ceramics, and semiconductors. It's also used in thermal management for electronics.

What's the difference between HPHT and CVD synthetic diamond powder?

HPHT powder offers superior toughness for grinding applications, while CVD powder provides exceptional purity and uniform particle shapes ideal for ultra-precise finishing and thermal applications.

Why choose synthetic over natural diamond powder?

Our synthetic diamond powder delivers consistent particle size distribution, higher purity (99.9%), and customizable properties - outperforming natural diamond in repeatability for industrial processes.

What particle sizes do you offer?

We provide synthetic diamond powder from 0-0.5μm (nano) to 50μm, with 15 standard grades optimized for lapping, polishing, or composite reinforcement applications.

Can your powder be used for thermal management?

Yes, our high-purity CVD diamond powder is specifically engineered for thermal interface materials, offering 1200-2000 W/mK thermal conductivity in electronics cooling solutions.

Synthetic Diamond Powder

Name: Premium Synthetic Diamond Powder - Supreme Abrasives
Brand: Supreme Abrasives
Rating: 4.9 (4327 reviews)

High-purity synthetic diamond powder designed for enhanced grinding, lapping, and polishing results.

Engineered using HPHT and CVD techniques, our synthetic diamond powders deliver unmatched durability, consistency, and precision.

Synthetic diamond powder is made from pure carbon under controlled high-pressure, high-temperature (HPHT) or CVD conditions. It replicates the strength of natural diamonds with enhanced purity and consistency — ideal for industrial use.

Diamond, the hardest known natural material, is composed entirely of pure carbon. While its natural form has been admired for centuries, scientists began exploring synthetic alternatives in the 18th century after confirming its carbon-based structure. It wasn’t until the 1950s that real breakthroughs occurred — thanks to advancements in high-pressure research and experimental technology — making synthetic diamond production commercially viable. Since then, synthetic diamonds have played a crucial role across various industrial sectors.

At Supreme Abrasives, we offer high-purity Synthetic Diamond Powder manufactured using two advanced techniques: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These processes replicate the conditions under which natural diamonds form but with controlled parameters to produce uniform, reliable results.

Our synthetic diamond powder is known for its exceptional hardness, thermal stability, and consistent particle size distribution. These qualities make it ideal for a wide range of applications, including semiconductor manufacturing, high-precision grinding, polishing, cutting, and thermal management in electronics.
