Le alloy iphinde yakha i-Glass evaliwe futhi elawulwa ingxube yokunweba,Ingxubevange ine ai-coefficient yokunwetshwa komugqaefana naleyo ye-silicon boron ingilazi eqinile ku-20-450 ° C, aindawo ephakeme ye-Curie, kanye nokuzinza okuhle kwesakhiwo esinezinga lokushisa eliphansi.Ifilimu ye-oxide ye-alloy iminyene futhi ingaba kahlemanzi tengeingilazi.Ayihlanganisi ne-mercury futhi ilungele ukusetshenziswa kumamitha wokulahla aqukethe i-mercury.Yisakhiwo esiyinhloko sokuvala amadivaysi e-vacuum kagesi.

I-1.I-Kovar isetshenziswa kabanzi embonini yezogesi, njengezingxenye zensimbi eziboshelwe ezimvilophini zengilazi eqinile.Lezi zingxenye zisetshenziselwa amadivaysi anjengamashubhu kagesi namashubhu e-X-ray, njll.
2.Embonini ye-semiconductor i-kovar isetshenziswa kumaphakeji avalwe nge-hermetically kuwo womabili amadivaysi esekethe adidiyelwe nahlukene.
I-3.Kovar inikezwa ngezindlela ezihlukahlukene ukuze kube lula ukukhiqizwa okuphumelelayo kwezingxenye ezihlukahlukene zensimbi.Inezici zokunweba ezishisayo ezifana nalezo zengilazi eqinile.Isetshenziselwa ukunwetshwa kwamalunga phakathi kwensimbi nengilazi noma izitsha zobumba.
I-4.Kovar alloy iyi-vacuum encibilikisiwe, i-iron-nickel-cobalt, i-alloy enwebekayo ephansi ukwakheka kwayo kwamakhemikhali kulawulwa ngaphakathi kwemikhawulo emincane ukuze kuqinisekiswe izici eziqondile ezifanayo zokunwetshwa kokushisa.Izilawuli zekhwalithi ezinabile zisetshenziswa ekwenziweni kwale alloy ukuze kuqinisekiswe izakhiwo ezifanayo ezingokomzimba nezomshini ukuze kube lula ekudwebeni okujulile, ukugxiviza kanye nokwenza imishini.
Inkambu yesicelo se-Kovar Alloy:
● Ingxubevange ye-Kovar isetshenziselwe ukwenza izimpawu ze-hermetic ngezingilazi ze-Pyrex eziqinile kanye nezinto zobumba.
●Le ngxubevange ithole ukusetshenziswa okubanzi kumashubhu kagesi, amashubhu e-microwave, ama-transistors nama-diode.Kumasekhethi ahlanganisiwe, isetshenziselwe iphakethe eliyisicaba kanye nephakheji ye-double-in-line.
