Tantalum(V) oxide, 99.95% (metals basis excluding Nb), Nb <200ppm, Thermo Scientific Chemicals
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.
