Nanometer Size Diamond Powders/Solutions/ Slurries

The unique expertise developed in-house for the characterization of diamond powders with respect to particle size, particle shape, surface cleanliness, and purity (extrinsic & intrinsic impurities) enables Engis Corp. to manufacture consistently high-quality nanometer-size diamond powders whose properties are precisely defined and controlled for consistent performance.

We offer nanometer-size diamond powders in custom sizes  and distributions upon customers' specific requirements.

We specialize in various applications:

• Lapping & polishing: HDD, Optics, Electronics
• Medical: drug delivery and imaging systems
• Thermal management
• Coatings

DIAMOND TYPES & MANUFACTURING METHODS

Diamond type: Monocrystalline

• Static HPHT Synthesis
• Static compression of graphite-metal catalyst mixture at HPHT (P > 50 Kbar; T >1400)

Diamond type: Engineered (Surface modified) Monocrystalline

• Modification of diamond surface via thermal processes (envelope of amorphous Carbon layer)

Diamond type: Polycrystalline

• Dynamic HPHT Synthesis – Indirect Explosion
• Shock wave compression of graphite-metal (Cu) mixture

Diamond type: Clusters of nano size diamond nanocrystallites – A.K.A. Nanodiamond

• Dynamic HPHT Synthesis – Direct Explosion
• Detonation of oxygen-deficient explosive mixture (TNT/RDX) in a closed chamber
• Laser treatment of targets containing carbon soot mixed within hydrocarbon media
