NANODIAMONDS

 

STS-ND: NANODIAMOND POWDER OF LASER SYNTHESIS

STS-ND is nanodiamond powder obtained by the unique technology using laser treatment of specially prepared targets containing carbon soot and hydrocarbons in liquid media. 

 

Specification:

•   Average crystal size: 4-5 nm

•   Crystal lattice constant: 0.3567 nm

•   Pycnometric density: 3.25 - 3.4 g/cm³

•   Bulk weight: 0.4 - 0.7 g/cm³

•   Incombustible residue: less than 0.01 wt. %

 

STS-ND is free of the drawbacks of detonation nanodiamonds - metal and graphite impurities.

APPLICATIONS

 

Current nanodiamond applications:

 

•    Lapping and polishing compositions (abrasives in pastes, gels, slurries for obtaining low-roughness surfaces)

•   Lubricants (oils and greases for engines, machine tools, gun barrels, friction pairs for wear-reducing and prolonging the shelf life of mechanisms)

•   Galvanic electrolytes (additives for improving the quality of coatings)

•   Polymers (additives for improving material characteristics)

•   Proteins (adsorbent for separation and purification)

•   Cosmetic products (additive for amplification of biological active agents and UV protection)

•   Explosives and solid propellants

 

Prospective nanodiamond applications:

 

•   Drug and gene delivery carrier

•   Biosensors

•   Advanced composites

•   Optical windows and filters

•   Optically transparent protective coatings

•   Photovoltaic cells

•   Heat spreaders for high-power laser diods

•   Substrates for multy-chip moduls

•   Field emission displays

•   Solar-blind UV and particles detectors

•   Quantum computers
