Nā Papa Rhenium

He keʻokeʻo keʻokeʻo ʻo Rhenium ma ke ʻano he ʻulaʻula metala. Loaʻa iā ia ka helu atomic o 75, ke kaumaha atomika o 186.207, ka helu heheʻe o 3180 ℃, kahi paila o 5900 ℃, a me ka nui o 21.04g/cm³. ʻO Rhenium kekahi o nā wahi heheʻe kiʻekiʻe loa o nā metala āpau. ʻOi aku ka helu heheʻe o 3180°C ma o ka tungsten a me ke kalapona wale nō. Hōʻike ia i ke kūpaʻa nui, ka lole a me ka pale ʻana i ka corrosion.

Hiki ke hoʻohana ʻia ka Rhenium i nā superalloys kiʻekiʻe no ka hana ʻana i nā ʻāpana mīkini jet. Hiki ke hoʻohana ʻia e like me ka rocket thrusters no nā satelite liʻiliʻi, nā mea pili uila, nā thermistors, nā ʻenekini turbine kinoea, nā thermocouples kiʻekiʻe a me nā ʻoihana ʻē aʻe.

ʻO Rich Special Materials kahi mea hana o Sputtering Target a hiki ke hana i nā papa Rhenium maʻemaʻe kiʻekiʻe e like me nā kikoʻī o nā mea kūʻai aku. No ka 'ike hou aku, e 'olu'olu e leka uila mai.
