Borona

Hōʻike ʻia ʻo Boron ma ka papa ʻaina me ka hōʻailona B, ka helu ʻātoma 5, a me ka nuipa atomika o 10.81. ʻO ka boron element, nona nā waiwai semi-metallic a me semi-conductive, aia i loko o ka hui 3A ma ka papaʻaina. Aia ʻo Boron ma ke ʻano he ʻelua isotopes - B10 a me B11. Ma keʻano laulā, loaʻa nā borates ma ke ʻano e like me ka B10, isotope 19.1-20.3% o ka manawa a me ka isotope B11 79-80.9% o ka manawa.

ʻO ka boron element, ʻaʻole i ʻike ʻia ma ke ʻano, hana i nā mea paʻa me nā mea metala a me nā mea ʻole metala e hana i nā pūhui me nā ʻano ʻokoʻa. No laila, hiki ke hoʻohana ʻia nā pūhui borate i nā ʻoihana like ʻole e pili ana i nā kemika paʻa like ʻole. ʻO ka maʻamau, hana nā pūhui boron e like me nā pūhui non-metallic, akā loaʻa i ka boron maʻemaʻe ka conductivity uila. He like ka boron crystallized i ka nānā aku, he mau waiwai optical e like me, a ʻaneʻane paʻakikī e like me nā daimana. Ua ʻike ʻia ka boron maʻemaʻe no ka manawa mua ma 1808 e nā mea hoʻomaʻamaʻa Farani ʻo JL Gay – Lussac lāua ʻo Baron LJ Thenard a me H. Davy chemist Pelekane.

Hoʻomākaukau ʻia nā pahuhopu e ka hoʻopili ʻana i nā pauka Boron i ka piha piha. Hoʻopili ʻia nā mea i hoʻopaʻa ʻia a laila hoʻokumu ʻia i ke ʻano i makemake ʻia.

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