Nanoparticle research has gained momentum over the recent years mainly due to the unexpected behavior of the basic elements when their atomic and molecular properties are altered. This article will look into the properties and applications of tantalum oxide.
Tantalum oxide (Ta2O5) nanoparticles are magnetic oxide nanoscale particles having a spherical form. These particles are available in coated, dispersed, nanofluid and ultra high purity forms. Tantalum belongs to Block D, Period 6 while oxygen belongs to Block P, Period 2 of the periodic table.
