Ukulethwa Okusha kwe-CAS 7803-62-5 Semiconductor Use Gas Silane/Silicon Tetrahydride

Le nhlangano iyaqhubeka nomqondo wenqubo othi “ukuphathwa kwesayensi, ikhwalithi ephezulu kanye nokusebenza kahle, umthengi ophakeme kakhulu we-New Delivery ye-CAS 7803-62-5 Semiconductor Use Gas Silane/Silicon Tetrahydride, Manje sibheke phambili ekubambisaneni okukhulu nakakhulu nabathengi baphesheya abathembele emibuthanweni efanayo. Uma unentshisekelo cishe kunoma yiziphi izixazululo zethu, qiniseka ukuthi uzizwa ungakhokhi ukusishayela ucingo ukuthola imininingwane eyengeziwe.
Le nhlangano iyaqhubeka nomqondo wenqubo othi “ukuphathwa kwesayensi, ikhwalithi ephezulu kanye nokusebenza kahle, umthengi ophakeme kakhuluI-China Silicon Tetrahydride kanye ne-SilaneUkuze ukwazi ukusebenzisa ulwazi oluvela olwazini olukhulayo kwezohwebo lwamazwe ngamazwe, samukela abathengi abavela kuyo yonke indawo ku-inthanethi nangaphandle kwe-inthanethi. Naphezu kwezixazululo zekhwalithi ezinhle esizinikezayo, insizakalo yokubonisana ephumelelayo neyanelisayo inikezwa yithimba lethu lezinsizakalo ezithengiswayo ngemuva kokuthengisa. Uhlu lwemikhiqizo kanye nemingcele eningiliziwe kanye nanoma yiluphi olunye ulwazi kuzothunyelwa kuwe ngesikhathi semibuzo yakho. Ngakho-ke sicela uxhumane nathi ngokusithumelela ama-imeyili noma usishayele ucingo uma unemibuzo mayelana nenkampani yethu. Ungathola futhi ulwazi lwekheli lethu ekhasini lethu lewebhu bese uza enkampanini yethu ukuze uthole ucwaningo lwemikhiqizo yethu. Siyaqiniseka ukuthi sizokwabelana ngempumelelo efanayo futhi sakhe ubudlelwano obuqinile bokubambisana nabangane bethu kule makethe. Silangazelela imibuzo yakho.

Imininingwane

I-sulfur tetrafluoride iyinhlanganisela engeyona engokwemvelo enefomula yama-molecule ye-SF4. Iyigesi engenambala, ebolile futhi enobuthi kakhulu endaweni ejwayelekile. Inesisindo sama-molecule esingu-108.05, iphuzu lokuncibilika elingu--124°C, kanye nephuzu lokubila elingu--38°C. Iyi-ejenti ekhethayo ye-organic fluorinating ephumelela kakhulu futhi esetshenziswa kabanzi. Ingakhipha i-carbonyl ne-hydroxyl ngokukhetha. Inesikhundla esingenakuguqulwa ekukhiqizweni kwamakhemikhali amahle, izinto zekristalu eliwuketshezi kanye nezimboni zemithi ezisezingeni eliphezulu. I-sulfur tetrafluoride iyi-ejenti ekhethayo ye-organic fluorinating. Iyigesi engenambala enephunga elinamandla elifana negesi ye-sulfur dioxide ngaphansi kokushisa okuvamile kanye nengcindezi. Inobuthi futhi ayishisi noma iqhume emoyeni; ku-600°C Isazinzile kakhulu. I-hydrolysis enamandla emoyeni ikhipha intuthu emhlophe. Ukuhlangana nomswakama endaweni kungabangela ukugqwala okufana ne-hydrofluoric acid. Uma i-hydrolyzed ngokuphelele ibe yi-sulfur dioxide kanye ne-hydrofluoric acid, uma i-hydrolyzed kancane, ikhiqiza i-thionyl fluoride enobuthi, kodwa ingamuncwa ngokuphelele yisisombululo esinamandla se-alkali ukuze ibe usawoti ongenabuthi futhi ongenangozi; ingancibilikiswa ku-benzene. I-sulfur tetrafluoride okwamanje iyi-ejenti ekhethayo ye-organic fluorinating esetshenziswa kabanzi. Ingakhipha i-fluorine ngokukhetha amaqembu e-carbonyl kanye ne-hydroxyl (ifaka i-oxygen kuma-compounds aqukethe i-carbonyl); isetshenziswa kabanzi kumakhemikhali amahle ezintweni zekristalu yoketshezi ephezulu kanye nokukhiqizwa kwezimboni zemithi nezibulala-zinambuzane ezisezingeni eliphezulu kunesikhundla esingenakufakwa esikhundleni. Ingasetshenziswa futhi kugesi kagesi, ukufakwa komphunga wamakhemikhali, i-ejenti yokwelapha ubuso, i-plasma dry etching kanye nezinye izici eziningi. Isetshenziswa ekuhlanganisweni kwezinto eziphilayo, iyi-reagent evamile yokwenza ama-fluorocarbon. I-sulfur tetrafluoride igcinwa endaweni yokugcina epholile, enomoya. Kufanele igcinwe ngokwehlukana nama-oxidants, amakhemikhali adliwayo, kanye nezinsimbi ze-alkali, futhi kude nemithombo yomlilo nokushisa.

Isicelo:

① I-ejenti ye-fluorination yemvelo:
I-ejenti ephumelela kakhulu yokukhetha i-fluorinating ephezulu isetshenziswa kabanzi ezintweni ezisezingeni eliphezulu zekristalu yoketshezi kanye nezibulala-zinambuzane eziqukethe i-fluorine, imithi kanye nezinto ezisetshenziswayo; ingasetshenziswa futhi njengegesi ye-electron, ukufakwa komphunga wamakhemikhali, izinto zokwelapha ubuso, ukugqwala okomile, i-plasma nezinye izici.

Iphakheji evamile:

Inzuzo:

①Iminyaka engaphezu kweyishumi emakethe;
②Umkhiqizi wesitifiketi se-ISO;
③Ukulethwa okusheshayo;
④Umthombo wezinto zokusetshenziswa eziqinile;
