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
