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
