ʻO Yttrium he mea hao-hina-hina, metala lepo laha ʻole. Paʻa maikaʻi ʻo Yttrium i ka lewa, no ka mea, pale ʻia ia e ka hana ʻana i kahi kiʻiʻoniʻoni oxide paʻa ma luna o kona ʻili, akā hiki ke hoʻoheheʻe ʻia ke hoʻomehana ʻia. Hoʻopili ʻo ia me ka wai e hoʻoheheʻe ʻia e hoʻokuʻu i ke kinoea hydrogen, a hui pū me nā ʻakika mineral. Hiki ke ʻā i ka ea ke ʻoi aku ka nui o ka 400 °C i ka ʻā ʻana a i ʻole ka huli ʻana o ka metala. Ke puunaue liilii ia ka yttrium, he pa'a loa ia i ka ea.
ʻO 10mm density cube i hana ʻia me 99.95% pureYttriummetal, kēlā me kēia cube i hana ʻia mai ka metala maʻemaʻe kiʻekiʻe a me ka hōʻike ʻana i ka ʻili honua maikaʻi a me nā lepili i kālai ʻia i ka laser. nā ʻaoʻao a me nā kihi a ʻaʻohe burrs
