Precious Metals Nanoparticles

Precious Metal Nanoparticles in a New Scientific Field that are neither Atomic nor Molecular Size

With a reliable quality control system, we supply nanoparticles consisting of homogeneously dispersed clusters.

Features

  • Superior nanoparticle homogenous dispersion stability with high precious metal concentration.
  • Compatible with the dispersion mediums of both binary system precious metal composition and water/organic solvents.

What is precious metals nanoparticles?

  • The precious metals Nano cluster (particle size 1-100 nm) being dispersed into liquid or solid form.
  • The protection compound to variation of protective agent gives stable colloid form.
