Tantalumndiyo yechitatu refractory simbi pashuretungstenuyerhenium. Tantalum ine nhevedzano yezvivakwa zvakanakisa senge yakakwira kunyungudika, yakaderera mhute pressure, yakanaka kutonhora kushanda kuita, kugadzikana kwekemikari, kusimba kwakasimba kune liquid metal corrosion, uye high dielectric constant ye surface oxide film. Iine zvakakosha zvikumbiro munzvimbo dzepamusoro-soro dzakadai semagetsi, simbi, simbi, indasitiri yemakemikari, alloys yakaoma, atomu simba, superconducting tekinoroji, mota dzemagetsi, aerospace, zvekurapa uye hutano, uye tsvakiridzo yesainzi. Parizvino, kushandiswa kukuru kwetantalum ndeye tantalum capacitors.
Tantalum yakawanikwa sei?
Pakati pezana ramakore rechinomwe, chicherwa chitema chinorema chakawanikwa kuNorth America chakatumirwa kuBritish Museum kuti ichengetedzwe. Mushure memakore angangosvika zana nemakumi mashanu, kusvika muna 1801, nyanzvi yekemisitiri yekuBritain Charles Hatchett akatambira basa rekuongorora chicherwa ichi kubva kuBritish Museum uye akawana chinhu chitsva kubva pachiri, akachitumidza kuti Columbium (yakazotumidzwa zita rekuti Niobium). Muna 1802, nyanzvi yekemisitiri yekuSweden, Anders Gustav Eckberg, akawana chinhu chitsva nekuongorora mineral (niobium tantalum ore) muScandinavian Peninsula, iyo acid yayo yakashandurwa kuita fluoride yakapetwa kaviri munyu ichibva yadzokororwa. Akatumidza chinhu ichi kuti Tantalum zita raTantalus, mwanakomana waZeus mungano yechiGiriki.
Muna 1864, Christian William Blomstrang, Henry Edin St. Clair Deville, naLouis Joseph Trost vakanyatsoratidza kuti tantalum uye niobium zvinhu zviviri zvakasiyana zvemakemikari uye zvakasarudza makemikari mafomu emamwe makomboni ane hukama. Mugore rimwe chetero, Demalinia yakapisa tantalum chloride munzvimbo yehydrogen uye yakagadzira tantalum simbi kekutanga kuburikidza nekuderedza kuita. Werner Bolton akatanga kugadzira simbi yakachena ye tantalum muna 1903. Masayendisiti ndiwo akatanga kushandisa nzira yekristallisation yakaturikidzana kubvisa tantalum kubva muniobium. Iyi nzira yakawanikwa neDemalinia muna 1866. Nzira inoshandiswa nevesainzi nhasi ndeye solvent extract ye tantalum solution ine fluoride.
Nhoroondo yekuvandudza ye tantalum indasitiri
Kunyange zvazvo tantalum yakawanikwa mukutanga kwezana remakore rechi19, hazvina kusvika muna 1903 kuti tantalum yesimbi yakabudiswa, uye kugadzirwa kwemaindasitiri kwetantalum kwakatanga muna 1922. 1956. United States ndiyo yakanga iri nyika yekutanga pasi rose kutanga kugadzira tantalum, uye yakatanga kugadzirwa kwemaindasitiri kugadzirwa kwesimbi tantalum muna 1922. Japan nedzimwe nyika dzechiCapitalist dzakatanga kusimudzira indasitiri yetantalum mukupera kwema1950 kana kutanga kwema1960. Mushure memakumi emakore ebudiriro, kugadzirwa kweindasitiri yetantalum yepasi rose kwasvika padanho rakakura. Kubva kuma1990, kwave nemakambani makuru matatu ekugadzira tantalum: Cabot Group kubva kuUnited States, HCST Group kubva kuGermany, uye Ningxia Oriental Tantalum Industry Co., Ltd. kubva kuChina. Aya mapoka matatu anoburitsa pamusoro pe80% yezvese pasi rose zvigadzirwa zvetantalum. Zvigadzirwa, tekinoroji tekinoroji, uye nhanho yemidziyo yeindasitiri yetantalum kunze kwenyika yakakwira, iyo inosangana nezvinodiwa zvekukurumidza kusimudzira kwesainzi uye tekinoroji.
Indasitiri yetantalum muChina yakatanga muma1960. Mumatanho ekutanga ekunyungudika kwetantalum uye kugadzirisa muChina, chiyero chekugadzirwa, tekinoroji, giredhi yechigadzirwa, uye mhando zvaive kumashure zvakanyanya kune izvo zvenyika dzakabudirira. Kubva kuma1990, kunyanya kubvira 1995, kugadzirwa uye kushandiswa kwetantalum muChina kwakaratidza kukurumidza kusimudzira maitiro. Mazuva ano, indasitiri yeTantalum yeChina yakawana shanduko kubva kudiki kuenda kuhombe, kubva kumauto kuenda kune asiri varwi, uye kubva mukati kuenda kunze, ichigadzira iyo yega maindasitiri system kubva kumigodhi, kunyungudutsa, kugadzirisa kusvika kune application. Zvigadzirwa zvepamusoro, zvepakati, uye zvakaderera zvakapinda mumusika wepasi rose mune zvese. China yave nyika yechitatu yakasimba kwazvo pasi rose mukunyungudusa nekugadzirisa tantalum, uye yapinda pakati penyika huru dzeindasitiri yetantalum.
Mamiriro Ekusimudzira eTantalum Indasitiri muChina
Kusimukira kweindasitiri yeChina tantalum kunotarisana nemamwe matambudziko. Kana paine kushomeka kwezvigadzirwa uye kushomeka kwezviwanikwa zvekushandisa. Hunhu hweChina hwakaratidzwa tantalum zviwanikwa zvakapararira mamineral veins, yakaoma mineral kuumbwa, yakaderera Ta2O5 giredhi mune yekutanga ore, yakanaka mineral embedding particle size, uye mashoma ehupfumi zviwanikwa, zvichiita kuti zviome kuvaka migodhi mikuru zvakare. Kunyange zvazvo tantalum yakakuraniobiummadhipoziti akawanikwa mumakore achangopfuura, iwo akadzama geological uye mineral mamiriro, pamwe nekuongororwa kwehupfumi, hazvina kujeka. Naizvozvo, pane zvakakosha nyaya nekupihwa kwekutanga tantalum raw materials muChina.
Indasitiri yetantalum muChina yakatarisanawo nerimwe dambudziko, rinova kusakwana kwekusimudzira kwezvigadzirwa zvepamusoro-soro. Hazvigoni kurambwa kuti kunyange zvazvo China tantalum indasitiri zvemichina uye midziyo akaita kufambira mberi kukuru uye vane kugadzirwa kukwanisa kuwanda kubudisa zvizere siyana tantalum zvigadzirwa, zvinonyadzisa mamiriro pamusoro vakawandisa pakati kusvika yakaderera kuguma uye kusakwana kugadzirwa kukwanisa yakakwirira-kuguma. zvigadzirwa zvakadai sepamusoro-soro simba rakakwirira-voltage tantalum poda uye tantalum yakananga zvinhu zve semiconductors zvakaoma kudzorera. Nekuda kwekushandiswa kwakaderera uye kusakwana kwekutyaira kwemaindasitiri epamusoro-tekinoroji, kusimukira kwezvigadzirwa zvepamusoro-soro muindasitiri yeChina tantalum kwakakanganiswa. Kubva pamaonero emabhizinesi, kusimudzira indasitiri yetantalum kunoshaya gwara uye mutemo. Mumakore achangopfuura, tantalum kunyungudutsa uye kugadzirisa mabhizinesi akakurumidza kukura kubva pa5 kusvika pamakumi maviri ekutanga, nekudzokorodza kwakakomba kwekuvaka uye kuwanda kwepamusoro.
Mumakore ekushanda kwepasirese, maChinese tantalum mabhizinesi akavandudza maitiro avo nemidziyo, akawedzera chigadzirwa chiyero, akasiyana, uye mhando, uye akapinda mumapoka makuru ekugadzira tantalum indasitiri uye nyika dzekushandisa. Chero bedzi isu tichienderera mberi nekugadzirisa matambudziko ezvigadzirwa, maindasitiri ezvigadzirwa zvepamusoro-soro, uye kugadziridzwa kwemaindasitiri, indasitiri yeChina tantalum ichapinda muzvikamu zvemasimba enyika.
