Beryllium (Be) Nanoparticles - Properties, Applications

Nanoparticles research is a vast area and the key benefit of nanoparticles is that their properties vary from bulk material of the same composition. Nanoparticles can be altered by varying their shape, size, and chemical environment.

Beryllium is a Block S, Period 2 element. It is a soft metal that is brittle but strong. The morphology of beryllium nanoparticles is spherical, and their appearance is a dark grey or black powder.

Beryllium nanoparticles can be surface functionalized, with organic molecules or polymers chemically bound to the particle surface. This can be used to tune the dispersion properties of the particles in suspensions or composites. This allows beryllium nanoparticles to be supplied as a nanofluid, in which the nanoparticles are suspended in solution.

Beryllium nanoparticles are graded as very toxic and should be handled with care. They cause skin and eye irritation, and could be fatal if inhaled. They have also been tested to be carcinogenic.
