He aha Kua whakangutungutu Metals?

Korero o konganuku whakangutungutu, kua mohio ki reira he aha konganuku hinga i raro i tenei tautuhinga. Vanadium, Tungsten, molybdenum, Niobium, rhenium, tantalum, zirconium me hafnium - konganuku nei rewa pāmahana tae 1650-1700 ° C.

I roto i te puka parakore, e kore e konganuku whakangutungutu tupu i roto i te āhua. E whiwhi ratou i aro ore te whakamahi i te matatini hangarau e toru-atamira. Kei roto i te taahiraa matamua i roto i te iritiraa i te kareti, ka i reira ko te wehe, me te purenga o pūhui matū, me te pae hopea - ora me te para o te whakarewa.

Ko whanui nui te hōkai o te whakamahi o konganuku whakangutungutu. konganuku whakangutungutu whakamahia i roto i te engineering aunoa, te pahi, hikohiko me te matū ahumahi, no te mea o ratou āhuatanga ahurei, ara o ratou te whakamahi rite wera alloys ātete rauemi.

Fakakaukau ki ia o konganuku whakangutungutu motuhake.

Vanadium - totoka whakarewa maitai-hina i roto i te tae. Ko te ingoa o tenei whakarewa i roto i te honore o te atua o te ataahua Vanadis, whakawhetai ki te tae o te tai e kua whakaurua i roto i tona hanganga. he ātete ki te wai, me te ngā waikawa Vanadium. Kei te whakamahia te reira i roto i te hanga o te rapa, uku, karaihe, me o steels akoranga. Ka rite ki te kawehiko pai i roto i te pākahiko whakamahia te vanadium pentoxide.

Tungsten - hina whakarewa totoka, te whakamahi i ngā āhuatanga paerewa taea te huaina reira te whakarewa tino whakangutungutu, whakamahia i roto i te metallurgy rite te pūtake. Ko te ingoa o te wolframite Tungsten kohuke riro i (i roto i te motokā. Ki reira. "Wolf pahuka i"), e i mohiotia i roto i te rau tau 15 rite Tungsten raruraru tine tango,. kitea e Wolfram tona tono i te hanga o kaipuke motuhake e whakamahia ana mō te tipu tioata kotahi, rewa karaihe, etc ..

Molybdenum - maitai whakangutungutu tae hiriwa-ma. Molybdenum whakauaua haria ki te hāora, me te tauhohe ki te hauwai puta ina tae molybdenum te ira whakakoero (2620 ° C). Ko tōna whakamahi i roto i te hanga o kakawaea mo rama hiko, me te mo te hanga o cathodes pūrere hiko.

Niobium - te marama whakarewa whakangutungutu hina, ngāwari treatable, ātete ki te waikura. He wāhanga o te he kowiri tira, wera-ātete, me te waikura-ātete alloys, te whakapai ake o ratou āhuatanga hangarau.

Ko Rhenium roto te nui tino o whakangutungutu konganuku. Alloys e whakamahia o tenei whakarewa hina marama ki Tungsten me molybdenum resistance ahi, me mo te hanga o te rererangi paorangi me missiles.

Tantalum - matū pūmau whakangutungutu hina te marama whakarewa ki te hue papura. whakamahia te metallurgy te rite te wāhanga o alloys waikura-ātete, wera-ātete, me te pakeke.

zirconium Pure he whakarewa pīataata i te mea ngāwari ki te tukatuka mahi e rua wera, me te matao. Ko te āhuatanga o te whakarewa i roto i taua kua reira he ātete tiketike rawa ki te waikura.

kitea Hafnium te i roto i tokahuke zirconium. Metal ki kanapa hiriwa, e whakamahia ki te whakaputa i otaota absorbent o reactors karihi.
