Field o tono, me ngā āhuatanga o te tātai Tungsten

He aha te mea Tungsten? Ko te āhuatanga matua o te huānga e hāngai ana i runga i nga peculiarities o tona hanganga matū. Homai te tono mo te Tungsten, me ata matau koe tona hanganga.

Ko te tūranga i roto i te Taka Pūmotu

Whakaaro i te āhuatanga taketake o te Tungsten, tīmata ki te meka e te mea i te tau 74th. I raro i ngā āhuatanga noa, tohu te reira i te whakarewa whakawhiti ia i te tae puru-hiriwa. he mārō Tungsten, kua he umeraa konganuku. Ko tenei te mea nui atu te ira whakakoero he waro anake te huānga tino whakangutungutu. ² 5p ⁶ 5d ⁴ 6s ² , E _ион (Ме => Ме ⁺ + e) = 7,98 э В. tātai Electronic: KLMN5s ² 5p ^{4 6} 5d 6s ^2, E _katote (ahau => ahau ^{+ +} e) = 7,98 e V.

me kī

Ko tōna ingoa rerekē herea tenei whakarewa te ki te wolframite kohuke. kua "pahuka i Wolf" Kua mohiotia mai te rautau 16. Tenei ingoa rerekē faataa e te aroaro o kohuke i roto i te reira tokahuke tine. haukotia Tungsten tine poorohe, te iritiraa i te reira ki te pahuka i slags. He aha e nga āhuatanga ōkiko o Tungsten ko te pūtake o tona whakamahi whānui i roto i te ahumahi? I roto i te Hononga o Amerika i huaina tenei whakarewa ko "kohatu taimaha".

I roto i te mutunga o te rau tau 18 tōnapi Scheele ki nitric waikawa tukinotia scheelite kohuke riro ia, te fariiraa i Tungsten trioxide. A iti i muri mai, te whakahaere nga teina ki te tiki Eliyar Tungsten waikura i wolframite Saxon. Ko enei Utaina, tāutuhia etahi i ngā āhuatanga matū o te Tungsten.

Te riroraa i roto i te āhua

He reira tetahi mea i roto i te āhua o te Tungsten parakore? āhuatanga matū o te whakarewa kōrero tona aroaro i roto i te kirinuku mo te wahi tino i roto i te puka o pūhui. Hei tauira, he ranunga o waikura o konupora, rino, Tungsten. Hoki ngā tono ahumahi tīpakohia te pūhui te ferberite me Gyubnera. He hakari i roto i te tua ki te Tungsten, rino, me te konupora ratou. ngā āhuatanga ōkiko o te Tungsten whakarewa, ka tukua ki te tohatoha o ngā kohuke Tungsten. I roto i te ratou, e kore e te kukū nui e rua ōrau. I roto i te putunga nui o Tungsten, mōhio tatou China, te US, Kazakhstan. I tua atu, i te tāutuhia me rahi rāhui o tokahuke whakarewa i roto i te Tonga Korea, Bolivia, Russia, Portugal. ngā āhuatanga ōkiko pai o te Tungsten amo tona production ahumahi nui. production ā-tau o te ao o e pā ana ki 50 mano toni o huānga whakangutungutu. Ko te ki täwahi, matua o te Tungsten whakaaro ko South Korea, China, Austria. I roto i te ngā kaiwhakauru o te nikau whakarewa whakangutungutu o te ārahitanga no ki te United Kingdom, Japan, USA, Germany.

production Āhuatanga

kawea faaineineraa o te Tungsten te i mā te taahiraa takawaenga, tera wehenga i ore kareti Tungsten trioxide. Next, kua whakamana reira ki whakahoki te paura whakarewa. he taahiraa taua e wahi i te pāmahana o e pā ana ki 700 degrees. He aha e nga āhuatanga ōkiko o te Tungsten kei i te ngakau o tenei hangarau? Te pāmahana rewa tiketike taea reira mā metallurgy paura i raro ki te puehu raungaitinga, sintering i roto i te huru hauwai i te pāmahana o e pā ana ki 1300 degrees. Next, i muri i haere te nāianei hiko Tungsten whiwhi te. A, no te tahu i te whakarewa te ki te pāmahana o 3000 nekehanga kitea rauemi nukurau. Na roto i te rohe rewa kawea i roto i purenga muri, me te faaineineraa o kotahi-karaihe whakarewa.

āhuatanga

He aha e nga āhuatanga o te Tungsten? āhuatanga matū e hāngai ana i runga i tona pāmahana rewa tiketike. Ko te huānga e te honohono, o i te 2 ki te 6. Ko te tēpara tino ki te valency o Tungsten ko ono. Metal āhuatanga e pai ake resistance waikura. e kore e oxidize te reira i roto i te hau i te pāmahana rūma. I roto i te Tungsten waikura, huri i te reira anake, no te te pāmahana o whakaiti ma. I roto i te raupapa iahiko o konganuku whakanuitia Kei huānga kaha te i muri i te hauwai, na e kore e he reira wairewa i roto i te memeha hydrofluoric me waikawa pungatara. taea ki te tareka te hauwai waikuratei, me te ranunga o ngā waikawa hydrofluoric me nitric Tungsten he.

I roto i te aroaro o hāora whakarewa kaha e taea o te tauhohe i ki alkalies whakarewa. Tuatahi, puta kaua āta te tauhohenga, engari i muri i te taenga ki te pāmahana o 400 nekehanga e tupu noa painaina te whakarewa, i accelerates te tauhohenga. Tungsten i roto i te ranunga o te waikawa hydrofluoric me hauota puka waikawa geksaftorvolframovuyu. Ko te nui mōrahi whakamahia i roto i te trioxide ahumahi Tungsten. I roto i tungstate He te kaha ki te hanga i tētahi anion polymeric. Tenei whakarewa Ko te pūtake o ngā rauemi whakangutungutu i roto i te ahumahi hou.

Me pēhea e taea te whakamahi ahau Tungsten carbide? Āhuatanga o te pūhui whakamahia ki te wehe i te reira i te Tungsten parakore. kua hanga reira te pūtake mo te hanganga o kakawaea i roto i turanga rama maha plasticity me konganuku whakangutungutu. I tua atu, whakamahia Tungsten te i roto i ngongo pikitia me korere mārua. Mai tenei huānga ko te kiato nui, kua meinga reira hei turanga mo te hanga o alloys taimaha. He mahuinga ia mo te hanganga o pauna ratou, me otaota mai patu-hohonu, tiketike-tere gyroscopes rotors mō missiles ballistic. Ko te pukapuka nui o Tungsten whakamahia te i roto i te fehokotaki'anga hauhauhā-pewa hei kawehiko. Alloys, i roto i tona hanganga Kei Tungsten, i te ātete wera nui, ātete waikawa, he ātete ki taumahatanga aunoa ratou. tukua taua āhuatanga ki te whakamahi ia ratou mo te hanga o mea hāparapara, tāke patu, engines rererangi, ki te whakanoho ipu o matū iraruke. E Tungsten Ko te wāhanga nui mo te hanga o ngā auroro maitai-te kounga tiketike.

Kei te whakamahia te reira i roto i tiketike pāmahana oumu mārua rite te huānga whakawera. I roto i te tahi thermocouples rhenium he ona koranu whakarato hoki taua oumu.

mutunga

Ko reira hoki te tiketike mātotoru o Tungsten he e tika ana mō te tiaki mata i ionizing radiation whakarewa. pakeke nui ake me refractoriness whakarewa hanga fifi tino i roto i tona tukatuka. Hei whakaoti i te raruraru whakaurua ki te konukōreko, parahi, me te rino. hanga Tungsten resistance kua rongonui te reira i roto i te hanga o ngā rauemi hanganga i roto i te engineering hou.

he tika hoki mira reira, te pao, tahuri, he kōhao. Hei tauira, titoa he wini te o Tungsten carbide. Kei te tono i tēnei ranunga ki te drill whakamahia ki te hanga i rua i roto i te raima. mahi Tungsten sulfide rite te hinu nui-pāmahana. kī ia i roto i te hanga. pūhui Tungsten Part whakamahia rite uhi me kaiwhakakökï. Hoatu tenei pūhui whakarewa me te rite te huānga alloying i roto i nga steels me alloys e hāngai ana i runga i te rino. uara koiora o te Tungsten whakarewa kore kua.
