Tantalum (Ta) Nanoparticles - Properties, Applications

Nanoparticles are currently being evaluated and used in many fields owing to their excellent diffusion and optical properties, ability to form suspensions and high surface area to volume ratio.

Tantalum is highly conductive to heat and electricity, and this property has made it the material of choice for electronic capacitors used in telecommunications and hand-held electronic equipment such as laptops and mobile phones.

Tantalum nanoparticles enhance the applications of the material due to their high surface area and ability to be dispersed in a printable ink. These nanoparticles should be stored in cool and dry room to prevent their dispersion performance from being affected by exposure to air.
