ʻAʻole ʻike pinepine ʻia ʻo Molybdenum, kēia metala -hinahinahina i loko o ko mākou ola i kēlā me kēia lā, akā aia ia a puni mākou ma nā ʻano like ʻole. Inā i loko o nā alloys, uea molybdenum no ka ʻoki uea, a i ʻole ka hoʻāʻo ʻana i ka pahuhopu molybdenum, hoʻokani mālie ka molybdenum i kāna kuleana. ʻO ka hoʻolaha hou ʻana e ka Ministry of Commerce a me ka General Administration of Customs o nā mana hoʻokuʻu aku i kekahi mau huahana molybdenum e hōʻike ana i ke koʻikoʻi o ka molybdenum.
Ma kona 'ano ma'ema'e, 'o ka molybdenum he metala -hinahinahina me ka pa'akikī Mohs he 5.5. ʻO kona helu heheʻe he 2623 degere a he 4639 degere ʻo ka paila ʻana, he kiʻekiʻe loa ia mau mea ʻelua no nā mea kūlohelohe. ʻO ka tantalum, osmium, rhenium, tungsten, a me kalapona wale nō ka nui o nā helu heheʻe. Hoʻomaka ka oxidation o Molybdenum ma 300 degere, he haʻahaʻa loa no nā metala kalepa. Eia kekahi, ʻo ka molybdenum ka helu haʻahaʻa loa o ka hoʻonui ʻana i ka wela, no laila he koho maikaʻi loa ia no nā noi wela kiʻekiʻe.
ʻAʻole loaʻa ka Molybdenum i kona ʻano metala maʻemaʻe ma ka Honua, akā ke kū nei ma ke ʻano he mau oxides i loko o nā minerala. Ma kona ano kumu, he metala hina -hinahina ka molybdenum me ke kala o ka hao hina. Loaʻa iā ia ke ono-kahi hoʻoheheʻe kiʻekiʻe loa o nā mea a pau. Hoʻokumu maʻalahi ka Molybdenum i nā carbide paʻa paʻa i loko o nā huila, e hopena ma kahi o 80% o ka lako molybdenum o ka honua i hoʻohana ʻia ma ke ʻano he mea hoʻohui i loko o ke kila, me ka ikaika kiʻekiʻe a me nā mea wela kiʻekiʻe.
Hiki ke hoʻoheheʻe ʻia ka hapa nui o nā pūhui molybdenum i loko o ka wai, akā hiki i ka molybdenum-me nā minelala ke hana i nā ion molybdenum (MoO2−4) ke ʻike ʻia i ka oxygen a me ka wai. Ma ka ʻoihana, hoʻohana ʻia nā pūhui molybdenum i nā noi kiʻekiʻe-a me ka wela-kiʻekiʻe, e like me nā puaʻa a me nā catalysts, e helu ana ma kahi o 14% o ka hana honua.
Ma waho aʻe o kāna mau noi ʻoihana, ʻo ka molybdenum kahi mineral koʻikoʻi no nā mea ola eukaryotic āpau, me nā kānaka. ʻO ia ka metala me ka helu atomika kiʻekiʻe loa ma waena o nā mea pono no ke ola eukaryotic. He ʻano hana like ʻole ka molybdenum-loaʻa nā enzyme cofactor i loko o nā mea ola. I kēia manawa, hoʻohana kekahi mau huakini i ka molybdenum-mea hoʻoheheʻe ma ke ʻano he mea hoʻoikaika maʻamau no ka uhaki ʻana i nā paʻa kemika o nā molekele naikokene lewa, e hiki ai ke hoʻopaʻa i ka nitrogen biological. ʻO ka liʻiliʻi he 50 molybdenum-loaʻa nā enzymes i ʻike ʻia i loko o ka bacteria a me nā holoholona, ʻoiai ʻo nā enzyme bacterial a cyanobacterial wale nō i komo i ka hoʻopaʻa ʻana o ka nitrogen. He ʻokoʻa ka molybdenum i loko o kēia mau nitrogenases mai ka molybdenum-ʻē aʻe i loaʻa nā enzymes, akā aia nā molybdenum oxidized ma ke ʻano he cofactor. Akā naʻe, ʻaʻole hoʻohana nā bacteria a pau i ka molybdenum. I kekahi mau bacteria a archaea, tungsten, he lālā o ka ʻohana like me ka molybdenum, ke pāʻani nei i kahi hana physiological e like me ka molybdenum i nā mea ola kiʻekiʻe.
Ma keʻano holoʻokoʻa, ʻo ka molybdenum kahi mea metala ʻokoʻa loa me ka nui o nā noi. He kuleana koʻikoʻi ia i ka hana ʻoihana a me ka biology.
