Ukuhlanzeka kwe-SiC powder kuzothinta ngqo ikhwalithi nokusebenza kwekristalu eyodwa ye-SiC ekhule ngendlela ye-PVT, futhi izinto zokusetshenziswa zokulungiselela i-SiC powder ziyi-purity ephakeme ye-Si powder kanye ne-high purity C powder, futhi ukuhlanzeka kwe-C powder kuzothinta ngokuqondile ubumsulwa be-SiC powder.
Izinto zokusetshenziswa ezisetshenziswa ekukhiqizeni i-toner ngokuvamile zihlanganisa i-flake graphite, i-petroleum coke kanye noyinki wetshe we-microcrystalline. Ukuphakama kokuhlanzeka kwegraphite, inani lokusetshenziswa liphezulu. Izindlela zokuhlanza i-graphite zingahlukaniswa zibe izindlela zomzimba nezindlela zamakhemikhali. Izindlela zokuhlanza umzimba zihlanganisa ukuntanta kanye nokuhlanza izinga lokushisa eliphezulu, futhi izindlela zokuhlanza amakhemikhali zifaka indlela ye-acid-base, indlela ye-hydrofluoric acid kanye nendlela yokuthosa i-chloride. Phakathi kwazo, indlela yokuhlanza izinga lokushisa eliphezulu ingasebenzisa indawo ephezulu yokuncibilika (3773K) kanye nephuzu elibilayo legraphite ukuze kuzuzwe i-4N5 nokuhlanzeka okuphezulu, okubandakanya ukuhwamuka nokuphuma kokungcola okunephuzu eliphansi lokubilisa, ukuze kuzuzwe inhloso ukuhlanzwa [6]. Ubuchwepheshe obuyinhloko be-toner yokuhlanzeka okuphezulu ukususwa kokungcola komkhondo. Kuhlanganiswe nezici zokuhlanzwa kwamakhemikhali kanye nokuhlanzwa kwezinga lokushisa eliphezulu, inqubo yokuhlanza i-thermochemical ephakeme ehlukaniswe izingxenye eziyingqayizivele iyamukelwa ukuze kufezwe ukuhlanzwa kwezinto ezihlanzekile ze-toner, futhi ubumsulwa bomkhiqizo bungaba ngaphezu kwe-6N.
Ukusebenza komkhiqizo nezici:
1, ubumsulwa bomkhiqizo≥99.9999% (6N);
2, ukuhlanzeka okuphezulu kwe-carbon powder ukuzinza, izinga eliphezulu le-graphitization, ukungcola okuncane;
3, imbudumbudu kanye nohlobo kungenziwa ngokwezifiso ngokusho kwabasebenzisi.
Ukusetshenziswa okuyinhloko komkhiqizo:
■ Ukuhlanganiswa kokuhlanzeka okuphezulu kwe-SiC powder nezinye izinto eziqinile zesigaba sokwenziwa kwe-carbide
■ Khulisa amadayimane
■ Izinto ezintsha ze-thermal conductivity zemikhiqizo ye-elekthronikhi
■ I-lithium battery cathode impahla esezingeni eliphezulu
■ Izithako zensimbi eziyigugu nazo ziyizinto ezingavuthiwe
