Incazelo emfushane:

Alloy-4J29 (i-alloy yokwandisa)
(Igama elijwayelekile: I-Kovar, NILO K, KV-1, Dilver Po, VaSton 12)
I-Alloy-4J29 eyaziwa nangokuthi kovar alloy. Yasungulwa ukuze ihlangabezane nesidingo se-seal ethembekile ye-glass-to-metal, okudingeka kumadivayisi we-elekthronikhi anjenge-balbs light, amashubhu we-vacium, amashubhu we-cathode ray, kanye nezinhlelo ze-vacuum ku-chemistry kanye nokunye ukucwaninga kwesayensi. Izinsimbi eziningi azikwazi ukubopha ingilazi ngoba ukwakhiwa kwazo kokunwebeka kwe-thermal akufani nengilazi, ngakho-ke njengoba ukuhlangana kupholile ngemuva kokuqanjwa kwezingcindezi zengilazi ngenxa yensimbi ehlukile yengilazi kanye nensimbi kubangele ukuhlanganisa.

I-Alloy-4J29 ayigcini nje ngokunwetshwa kwengilazi okufana nengilazi, kepha ijika lokunwebeka elingaphansi le-nonlinear lingenziwa ngokuvamile ukufanisa ingilazi, ngaleyo ndlela kuvume ukuhlanganiswa ukubekezelela ububanzi bokushisa obubanzi. Ngokwekhemikhali, izibopho zengilazi nge-Intermemediate axide ungqimba we-nickel oxide kanye ne-cobalt onide; Ingxenye ye-Iron Oxide iphansi ngenxa yokuncishiswa kwayo nge-cobalt. Amandla ebhondi ancike kakhulu ku-oxide ungqimba nobukhulu kanye nomlingiswa. Ukuba khona kwe-cobalt kwenza i-oxide urler ibe lula ukuncibilika futhi incibilikisa ingilazi ebilisiwe. Umbala ompunga, ompunga noma onsundu ohlaza okwesibhakabhaka ukhombisa uphawu oluhle. Umbala wensimbi ukhombisa ukuntuleka kwe-oxide, kanti umbala omnyama ukhombisa insimbi exutshwe ngokweqile, kuzona zombili lezi zimo eziholela ekuhlanganiseni okubuthakathaka.

Isicelo:Isetshenziswa kakhulu ezingxenyeni ze-vacuum kagesi kanye nokulawulwa kokuphuma, ishubhu ethukile, i-tube ye-tube, ama-magnall, ama-plug, ama-plug ahlanganisiwe, ama-chassis, amabakaki nezinye izindlu.
