Tungsten, simbi inoshandura inozivikanwa nekuoma kwayo kwakasarudzika, nzvimbo yakakwira yekunyungudika, uye kufambisa kwemagetsi, inoita basa rakakosha muindasitiri yemagetsi nemagetsi. Hunhu hwayo hwakasiyana hunoita kuti ive yakakosha mukugadzirwa kwezvinhu zvakasiyana-siyana zvakakosha kune tekinoroji yemazuva ano. Kubva pamafilamendi mumagirobhu emwenje kusvika kuzvikamu zvakakosha mumasemiconductors uye nekupfuura, mupiro we tungsten kune ino chikamu haugone kuwedzeredzwa.
Tungsten's Properties: Iyo Nheyo Yekushandisa Kwayo
Usati waongorora mashandisiro ayo, zvakakosha kuti unzwisise zvivakwa zvinoita kuti tungsten ive yakakosha muindasitiri yemagetsi nemagetsi.
High Melting Point: Tungsten ine nzvimbo yakanyanya kunyungudika yesimbi dzese, pa3,422°C (6,192°F). Izvi zvinoita kuti zvive zvakanaka kune zvikumbiro zvinoda kugadzikana pakupisa kwakanyanya, senge mumwenje bulb filaments uye yakakwirira-simba semiconductors.
Kufambisa kweMagetsi: Tungsten's yakanakisa magetsi conductivity yakakosha mumashandisirwo akaita semagetsi uye mabatiro mumagetsi akasiyana siyana.
Kuchengetedza Kwemhepo: Yayo yakakwirira yekupisa conductivity inobvumira tungsten kunyatsobvisa kupisa, izvo zvakakosha mukudzivirira kupisa muzvikamu zvemagetsi.
High Density uye Kuoma: Tungsten's density uye kuomarara kunoita kuti isarambe kupfeka uye deformation, kuve nechokwadi chekugara kwenguva refu muzvikamu zvinosangana neakakosha mechaniki kushushikana.
Kurwisana Kurwisana: Kuramba kweTungsten pakuora kunowedzera kusimba kwayo, zvichiita kuti ive yakakodzera kushandiswa kwenguva refu munzvimbo dzakaoma.
Nhoroondo Yemamiriro ezvinhu: Tungsten's Emergence muElectronics Indasitiri
Chekutanga chakakosha cheTungsten muindasitiri yezvemagetsi chakatangira kutanga kwezana ramakore rechi20 nekuuya kwegirobhu remwenje. Kuedza kwaThomas Edison nezvinhu zvakasiyana-siyana zvefilament zvakazoita kuti pave nekushandiswa kwe tungsten, iyo yakaratidza kuva yakakwirira zvikuru nekuda kwekunyungudika kwayo uye kugara kwenguva refu. Izvi zvakaratidza kutanga kwekushandiswa kukuru kwe tungsten muindasitiri iyi.
Kwemakumi emakore, basa retungsten rakawedzera sezvo matekinoroji matsva akabuda. Kuvandudzwa kwemachubhu evacuum, ayo aive akakosha muredhiyo neterevhizheni, aivimba zvakanyanya netungsten filaments. Sezvo indasitiri yemagetsi yakashanduka, ndozvakaitawo mashandisirwo etungsten, kubva kune transistors kuenda kumazuva ano semiconductors.
Tungsten muKuvhenekera: Iyo Incandescent Bulb uye Beyond
Iyo inonyanya kuzivikanwa kushandiswa kwe tungsten muindasitiri yemagetsi iri mune incandescent bulbs. Tungsten filaments yakanakira chinangwa ichi nekuda kwekugona kwavo kutsungirira tembiricha yepamusoro inodiwa kugadzira chiedza. Kana magetsi achipfuura nemufilament, inopisa kusvika painoburitsa chiedza chinooneka, zvese izvi zvichichengetedza kuvimbika kwechimiro nekuda kwekunyungudika kwetungsten.
Nekudaro, kushandiswa kwe tungsten mukuvhenekesa kwakashanduka nekuuya kwehunyanzvi hwekuvhenekesa. Kunyangwe ma bulbs e-incandescent akatsiviwa neakawanda-anoshanda simba mamwe mamwe senge maLED uye compact fluorescent marambi (CFLs), tungsten ichiri kukosha. Semuenzaniso, tungsten inoshandiswa mumarambi ehalogen, inova rudzi rwemwenje we incandescent unoshanda patembiricha yakakwira kuburitsa chiedza chakajeka. Mwenje iyi inoshandisa tungsten filament yakakomberedzwa nekashoma kehalogen gasi, iyo inobatsira kuwedzera hupenyu hwefilament nekuvandudza kushanda kwayo.
Tungsten muSemiconductors: Chinhu Chinokosha
