Isembozo esihlanganisiwe sesithando sesitofu sikagesi ngaphezulu

Ama-preforms ophahleni lwesithando sikagesi enziwe nge-corundum, i-SiC, i-mullite nezinye izinto ezinokumelana okuhle kokugqoka nokuqina kokushisa okukhulu okushisayo njengezinto ezisemqoka, nama-micropowders akhethekile ayinhlanganisela afakwa njenge-ejenti ebophayo, ekhiqizwa ngenqubo ekhethekile yokusakaza nokubhaka . Into efanelekile phezulu kwamakhishi kagesi. Izici zayo eziyinhloko ukuthi ingamelana nemisebe ephakeme yokushisa (2400 ° C) yokukhanya kwe-arc, inokuqina kokugqoka okungcono, ukuzinza okuphakeme kokushisa, ukubukeka okunembile nosayizi, nokuqina okuqinile nokuqina kokumelana. Isetshenziswa kabanzi ezithandweni ezinamandla amakhulu kagesi ekhaya nakwamanye amazwe ngemiphumela emihle.
