    ʻO Kina samarium oxide, i kapa ʻia ʻo Samaria, loaʻa iā Samarium kahi mana hoʻoheheʻe neutron kiʻekiʻe, ua hoʻohana kūikawā ʻo Samarium Oxides i ke aniani, phosphors, lasers, a me nā mea thermoelectric.

    Ua hoʻohana ʻia nā kristal Calcium Chloride i mālama ʻia me Samarium i nā lasers e hoʻopuka ana i nā kukuna o ka māmā e hiki ai ke puhi i ka metala a i ʻole ka lele ʻana i ka mahina.

    Hoʻohana ʻia ʻo Samarium Oxide i loko o ke aniani aniani a me ka infrared e hoʻoheheʻe i ka radiation infrared. Eia kekahi, hoʻohana ʻia ia ma ke ʻano he neutron absorber i nā koʻokoʻo mana no nā reactors mana nuklea.

    Hoʻopili ka Oxide i ka dehydration o nā waiʻona mua acyclic i nā aldehydes a me nā ketones.
