ʻO Tungsten a me ka molybdenum he mau mea hoʻololi i loaʻa kahi helu heheʻe kiʻekiʻe a me ka lōʻihi e kūpono iā lākou no kahi ākea o nā noi. Hoʻohana maʻamau ʻia kēia mau mea ʻelua e like me nā moku evaporation ma muli o ko lākou kūpaʻa kiʻekiʻe-mehana a me ke kaomi mahu haʻahaʻa. Eia nō naʻe, aia kekahi mau ʻokoʻa ma waena o nā moku tungsten a me molybdenum e pili ana i kā lākou noi, a mākou e kūkākūkā ai ma kēia ʻatikala.

Nā waʻa tungsten:

Hoʻohana pinepine ʻia nā waʻa Tungsten no ka hoʻoheheʻe ʻana i ka wela o nā metala a me nā alloys, a me nā mea kūlohelohe. ʻO kēia ma muli o ko lākou helu heheʻe kiʻekiʻe (3,422 ° C) a me ke kaomi mahu haʻahaʻa, kahi e hāʻawi ai i kahi kumu hoʻoheheʻe maʻemaʻe. Hoʻohui ʻia, hoʻohana pū ʻia nā moku tungsten i ka ʻoihana semiconductor ma ke ʻano he mea hoʻomehana ma muli o ko lākou conductivity thermal kiʻekiʻe a me ka paʻa mechanical maikaʻi ma lalo o nā kūlana kiʻekiʻe.

Loaʻa nā waʻa Tungsten ma nā ʻano like ʻole a me nā nui, me ka pōʻai, rectangular, a me ka cylindrical. Hoʻohana nui ʻia nā moku tungsten pōʻai no ka evaporation thermal, aʻo nā moku tungsten cylindrical e hoʻohana ʻia no nā mea wela. Hoʻohana ʻia nā moku tungsten rectangular no ka evaporation thermal a me nā noi hoʻomehana.

ʻO kahi hemahema o nā waʻa tungsten ʻo ko lākou makemake e pane me kekahi mau mea. No ka laʻana, hiki i nā waʻa tungsten ke hana me kekahi pūhui oxygenating e like me ka wai, oxygen, a me ka nitrogen e hana i ka tungsten oxide, hiki ke hopena i ka hōʻino ʻana o ka mea hoʻomehana. ʻO ka hopena, he mea nui e mālama i nā waʻa tungsten i loko o kahi ʻōpala a i ʻole kahi lewa inert.

Nā moku Molybdenum:

Hoʻohana nui ʻia nā waʻa Molybdenum no ka hoʻoheheʻe ʻana i ka wela o nā metala, nā ʻāpana, a me nā mea kūlohelohe. Loaʻa i nā moku molybdenum kahi helu heheʻe o 2,610 ° C a me ke kaomi mahu haʻahaʻa, e hoʻolilo iā lākou i koho maikaʻi loa no nā noi wela kiʻekiʻe. Hoʻohana ʻia lākou i ka ʻoihana semiconductor, ʻoi aku hoʻi no ka hana ʻana i nā mea hana silicon.

Loaʻa nā moku Molybdenum i nā ʻano like ʻole a me nā nui, e like me ka pōʻai, rectangular, a me ka cylindrical. Hoʻohana ʻia nā moku molybdenum pōʻai no ka evaporation thermal, aʻo nā moku molybdenum cylindrical e hoʻohana ʻia e like me nā mea hoʻomehana.

ʻO nā moku Molybdenum he haʻahaʻa haʻahaʻa e hana me nā mea like ʻole, ke hoʻohālikelike ʻia me nā moku tungsten. ʻO kēia ma muli o ke kūpaʻa kemika kiʻekiʻe o ka molybdenum e kū ai i ka oxidizing a me ka hoʻohaʻahaʻa ʻana i nā kaiapuni. No laila, kūpono lākou no nā mea e pono ai ka maikaʻi a me ka maʻemaʻe.

I ka hōʻuluʻulu ʻana, loaʻa i nā moku tungsten a me ka molybdenum nā waiwai kūʻokoʻa i kūpono iā lākou no nā noi like ʻole. He kūpono nā waʻa Tungsten no ka hoʻoheheʻe ʻana i ka wela a me nā noi hoʻomehana e koi ai i nā wahi hoʻoheheʻe kiʻekiʻe a me ke kūpaʻa. Ma ka ʻaoʻao ʻē aʻe, kūpono nā moku molybdenum no nā noi wela kiʻekiʻe e koi ai i ke kūpaʻa kemika kiʻekiʻe a me ke kūʻē ʻana i ka oxidation a me ka hōʻemi. No laila, pono e noʻonoʻo i ka noi kikoʻī i ke koho ʻana ma waena o nā moku tungsten a me molybdenum.
