Description

Tantalum (V) oxide (Ta2O5) has potential applications as part of an environmental barrier coating system for Si3N4-based turbine components. Octadecyl phosphoric acid ester has been found to produce oriented, well-ordered monolayers on a flat tantalum (V) oxide surface, via self-assembly from a heptane/propan-2-ol solution. Tantalum(V) oxide (Ta 2 O 5 ) has been used extensively as an insulating layer in discrete capacitors and shows a high potential for semiconductor applications such as an insulating dielectric in the capacitive element in memory devices such as dynamic random access.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
