Molybdenum Introduction

ʻO Molybdenum (Molybdenum) kahi mea metala hoʻololi i loko o ka Pūʻulu VI B (hui chromium) o ka manawa ʻelima o ka papaʻaina. ʻO ka hōʻailona ʻo Mo, ʻo kona helu ʻātoma he 42, a ʻo kona nui ʻātoma pili he 95.95. ʻO kona mānoanoa pili he 10.28 g/cm³, ʻo kona helu hoʻoheheʻe ʻo 2622 degere, a ʻo kona wahi e hoʻolapalapa ai ʻo 4639 degere. ʻO 5.2×10-8 Ω·m (20 degere ).
Loaʻa i ka Molybdenum ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me nā waiwai mechanical maikaʻi loa, e mālama ana i kēia mau ikaika kiʻekiʻe a paʻakikī a hiki i nā wela kiʻekiʻe. Hoʻohana nui ʻia ka Molybdenum i ka hana kila, a ʻo nā kila kila i hoʻohui ʻia i ka molybdenum i loaʻa ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ke kūpaʻa wela koʻikoʻi, a me ka pale ʻana i ka corrosion. Hoʻohana nui ʻia ka metallic molybdenum i nā mea uila e like me nā paipu electron, transistors, a me nā mea hoʻoponopono.
ʻO nā pūhui molybdenum koʻikoʻi he molybdenum oxide, molybdenum sulfide, molybdates, a me nā polyacids molybdenum. Loaʻa ka molybdenum ma ke ʻano he molybdenite (i haku mua ʻia me ka molybdenum disulfide). Hoʻopili ʻia ka molybdenite i ka molybdenum oxide, a laila hoʻemi ʻia me ke ʻano hydrogen a i ʻole aluminothermic e hana ai i ka molybdenum elemental. Hoʻohana nui ʻia ʻo Molybdenum i nā alloys kūikawā, nā electrodes, a me nā catalysts. He mea pono ia no ke kino kanaka.
