Application of Tantalum Pentoxide Evaporation Materials

Ta2O5 has high reflectivity and transmittance in the visible and infrared regions and has been used in AR coatings, lasers, optical communications, solar cells and other components. The tantalum pentoxide layer has a high dielectric constant and is also an important material for manufacturing a grinding container.


SAM’s tantalum pentoxide evaporation pellets are carefully packaged in the plastic vacuum bag to prevent damage during storage and transportation and to preserve the quality of our products in their original condition. Also, the COA of the raw material would be packaged with the product.

I ordered these for some science experiments. They are a great range of sizes and arrived unbroken! Each one is packed in its own box and then all are in a larger box.
