Graphite ine silicon imhando yezvinhu zvakasanganiswa umo silicon carbide inosungirirwa pamusoro pe graphite substrate. Ine hunhu hwekuomarara kwakanyanya, simba guru remakanika uye kuramba kupfeka kwe silicon carbide, pamwe nehunhu hwekuzvizora wega uye kuramba kupisa kwe graphite. Imhando yakanaka yezvinhu zvekukweshana uye zvinhu zvemakanika, zvakakodzera kuvharwa kwepombi dzemvura dzakasiyana-siyana, pombi dzemafuta, pombi dzemakemikari, uye mabheyaringi epombi huru dzinomhanya zvakanyanya uye dzine mutoro wakawanda. Pamusoro pezvo, siliconized graphite ine kuramba kwakanaka kwe oxidation, kuramba kupisa, porosity yakaderera, uye mamwe magetsi anofambiswa, uye inogona kushandiswa sezvinhu zvakaita sesimbi inonyungudutsa machubhu uye draft tubes.

Kuumbwa kwesiliconizedGraphite yakafanana, pamusoro payo panoenderana nemukati, uye huwandu hwesilicon carbide negraphite hunogadziriswa. Kana silicon carbide yakakwira, huwandu hwezvinhu zvacho hunokura, simba rekumanikidza rinokwira, uye resistivity inowedzera.
