Tantalum (V) oxide (Ta2O5 a i ʻole tantalum pentoxide)he hui paa paa keokeo. Hoʻopuka ʻia ka pauda ma ka hoʻoheheʻe ʻana i kahi tantalum i loaʻa i ka waiʻawaʻa, kānana i ka precipitate, a me ka calcining i ka keke kānana. Hoʻopili pinepine ʻia i ka nui o ka ʻāpana i makemake ʻia e hoʻokō i nā koi noi like ʻole.
