Siliconized graphite chinhu chakaumbwa umo silicon carbide inosungirirwa pamusoro peiyo graphite substrate. Iyo ine hunhu hwekuomarara kwepamusoro, kusimba kwemagetsi uye kupfeka kuramba kwesilicon carbide, pamwe neiyo yega-yekuzora zvivakwa uye thermal shock resistance yegraphite. Icho chinhu chakanakira kukweshera uye michina yekusimbisa zvisimbiso, yakakodzera kuvharwa kwemakanika kwepombi dzemvura dzakasiyana, pombi dzemafuta, pombi dzemakemikari, uye mabhengi emhando dzakasiyana-siyana dzekumhanya uye dzakakwirira-mutoro. Pamusoro pezvo, siliconized graphite ine yakanaka oxidation kuramba, kupisa kutyisa kuramba, kuderera kweporosity, uye mamwe magetsi conductivity, uye inogona kushandiswa semidziyo yakaita sesimbi inonyungudutsa crucibles uye dhizaini machubhu.
Iko kuumbwa kwesiliconized graphite kwakafanana, iyo yepamusoro inopindirana nechomukati, uye chiyero chekuumbwa kwesilicon carbide uye graphite inogadziriswa. Iyo yakakwira zvirimo zvesilicon carbide, iyo yakakura kuwanda kwezvinhu, iyo inokwirisa iyo yekumanikidza simba, uye resistivity inowedzera.
