Imikhiqizo ye-Tungsten isetshenziswa ezimbonini zikagesi nezikagesi

I-Tungsten, insimbi yoguquko eyaziwa ngokuba lukhuni kwayo okungavamile, indawo encibilika kakhulu, kanye nokusebenza kukagesi, idlala indima ebalulekile embonini yezogesi kanye nogesi. Izakhiwo zayo eziyingqayizivele ziyenza ibaluleke kakhulu ekukhiqizeni izingxenye ezihlukahlukene ezibalulekile kubuchwepheshe besimanje. Kusukela kuma-filaments kuma-light bulb kuya ezingxenyeni ezibalulekile kuma-semiconductors nangale kwalokho, umnikelo we-tungsten kulo mkhakha awunakweqiwa.

Izakhiwo zikaTungsten: Isisekelo Sezicelo Zaso

Ngaphambi kokungena ekusetshenzisweni kwayo, kubalulekile ukuqonda izakhiwo ezenza i-tungsten ibaluleke kakhulu embonini ye-elekthronikhi nekagesi.

I-High Melting Point: I-Tungsten inendawo ephakeme kakhulu yokuncibilika kuzo zonke izinsimbi, ku-3,422°C (6,192°F). Lokhu kuyenza ifanelekele izinhlelo zokusebenza ezidinga ukuzinza emazingeni okushisa aphezulu, njengakuma-filaments amalambu okukhanya nama-semiconductors anamandla aphezulu.

Ukusebenza kukagesi: Ukusebenza kahle kukagesi kwe-Tungsten kubalulekile ezinhlelweni ezifana nama-electrode noxhumana nabo kumishini kagesi ehlukahlukene.

Ukuqhuba Ukushisa: I-thermal conductivity yayo ephezulu ivumela i-tungsten ukuthi ikhiphe kahle ukushisa, okubalulekile ekuvimbeleni ukushisa ngokweqile ezingxenyeni zikagesi.

Ukuminyana Okuphezulu Nokuqina: Ukuminyana nobulukhuni be-Tungsten kuyenza imelane nokuguga nokuguqulwa, iqinisekisa ukuphila isikhathi eside ezingxenyeni ezibhekana nengcindezi enkulu yokusebenza.

Ukuphikiswa Kwe-Corrosion: Ukumelana nokugqwala kwe-Tungsten kukhulisa ukuqina kwayo, kuyenze ifanelekele ukusetshenziswa isikhathi eside ezindaweni ezinokhahlo.

Umongo Womlando: Ukuvela kuka-Tungsten embonini ye-Electronics

Isicelo sokuqala esibalulekile sika-Tungsten embonini ye-elekthronikhi sisukela ekuqaleni kwekhulu lama-20 ngokufika kwesibani se-incandescent. Ukuhlola kukaThomas Edison ngezinto ezihlukahlukene zemicu ekugcineni kwaholela ekusetshenzisweni kwe-tungsten, eyabonakala ingcono kakhulu ngenxa yezinga layo eliphakeme lokuncibilika nokuhlala isikhathi eside. Lokhu kwaphawula ukuqala kokusetshenziswa kakhulu kwe-tungsten embonini.

Phakathi namashumi eminyaka, indima ye-tungsten yanda njengoba kuvela ubuchwepheshe obusha. Ukuthuthukiswa kwamashubhu e-vacuum, ayebalulekile emsakazweni nakuthelevishini, kwakuncike kakhulu emiculweni ye-tungsten. Njengoba imboni ye-elekthronikhi ithuthuka, kanjalo nokusetshenziswa kwe-tungsten, kusuka kuma-transistors kuya kuma-semiconductors esimanje.
