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
