Yini i-hafnium tetrachloride esetshenziselwa?

Hafnium tetrachloride, obeye aziwe njengohafnium (iv) chloride or HFCL44, iyingxenye yenombolo ye-CAS1349-05-3. Ibonakala ngokumsulwa okuphezulu, imvamisa 99.9% kuya ku-99.99%, kanye nokuqukethwe okuphansi kwe-zirconium, ≤0.1%. Umbala wezinhlayiya ze-hafnium tetrachloride uvame ukuba mhlophe noma uphumele-mhlophe, ngobuningi bama-3.89 g / cubic centimeter kanye nephuzu elincibilikayo le-432 ° C. Ngokuphawulekile, kuyaphuka emanzini, okukhombisa ukuthi iphendula ngomswakama.

Hafnium tetrachlorideIngasetshenziswa njenge-Presersor ekukhiqizweni kwe-ceramics yokushisa ephezulu kakhulu. Yaziwa ngokuqina kwabo okuhle kakhulu, lezi zi-ceramics zisetshenziswa ezinhlelweni ezahlukahlukene zokushisa okuphezulu, ezinjengezinhlelo zokuvikela ukushisa embonini ye-aerospace kanye nokwenziwa kwamathuluzi okusika kanye ne-turtibles. Ikhono lekhompiyutha lokubekezelela amazinga okushisa aphezulu likwenza kube yingxenye ebalulekile ekuthuthukisweni kwezinto zokwakha ubuchwepheshe obuthuthukile kanye nokusetshenziswa kwezimboni.

Ngaphezu kwalokho,hafnium tetrachlorideUdlala indima ebalulekile emkhakheni wama-LED aphezulu aphezulu. Kusetshenziswa ekukhiqizweni kwama-phosphors, abucayi ekusebenzeni kwama-LED. Ama-phosphors ayizinto zokwakha ezikhipha ukukhanya lapho zivezwa ngemisebe futhi zihlanganiswe ekusebenzeni kwe-LED ngokuguqula ukukhanya okuluhlaza okwesibhakabhaka kube neminye imibala, kuthuthukise ikhwalithi yombala.

Ubumsulwa obuphezuluhafnium tetrachlorideKungenziwa ngokwezifiso ukwehlisa okuqukethwe ze-zirconium ku-200ppm, ukuqinisekiswa ukuthi kufanelekile ukuthola izicelo ezifunwayo lapho ukungcola kungathinta kabi umkhiqizo wokugcina. Leli zinga lobumsulwa libalulekile ekuhlolweni okuphumelelayo kwezinto ezithuthukisiwe, lapho ukulawula okuqondile kwe-Chemical Composition kubalulekile.

Ngokufigqiwe,hafnium tetrachloride, Ngokuhlanzeka kwayo okuhle kanye nezakhiwo ezihlukile, sekuyinto ebalulekile ebaluleke kakhulu ekukhiqizweni kwe-ceramics yokushisa ephezulu kakhulu futhi idlala indima ebalulekile ekuthuthukisweni kobuchwepheshe be-LED ephakeme. Ukuguquguquka kwayo kanye nokuvuselelwa kwayo kwenza kube yingxenye ehlanganisiwe ekuthuthukisweni kwezinsizakusebenza zokusika izinsiza zezimboni nezobuchwepheshe.
