Nanoparticle research has come up with innovative solutions that are useful the field of cosmetics, bio medicine, and electronics; which were not possible with elements in their original states.
Tungsten carbide (WC) nanoparticles are available as nanodots, dispersed and in passivated ultra pure forms. These nanoparticles are insoluble in cold water, exhibit a strong resistance to acids and have a high elastic modulus.
These nanoparticles should be stored under cool, dry, vacuum conditions and should not be subjected to any stress. Tungsten is a Block D, Period 6 element and carbon is a Block P, Period 2 element.
