Silicon carbide inoita kunge dhaimondi. Haisi iyo yakareruka chete, asiwo yakaomesesa ceramic zvinhu uye ine yakanakisa yekupisa conductivity, yakaderera kupisa kwekuwedzera uye inopikisa zvakanyanya kune acids uye lyes.
Nesilicon carbide ceramics zvinhu zvenyama zvinoramba zvakagadzikana kusvika kune tembiricha iri pamusoro pe1,400°C. Iyo yakakwira Young's modulus> 400 GPa inovimbisa yakanakisa dimensional kugadzikana. Izvi zvinhu zvinogadzira silicon carbide kufanotemerwa kushandiswa sechinhu chekuvaka. Silicon carbide masters corrosion, abrasion uye erosion zvine hunyanzvi sezvainomira kusvika pakupfeka. Zvikamu zvinoshandiswa mumakemikari zvidyarwa, zvigayo, zvinowedzera uye extruder kana se nozzles, semuenzaniso.
"Misiyano yeSSiC (sintered silicon carbide) uye SiSiC (silicon infiltrated silicon carbide) yakazvisimbisa. Iyo yekupedzisira inonyanya kukodzera kugadzirwa kwezvinhu zvakaoma-mavhoriyamu makuru. "
Silicon carbide ine toxicologically yakachengeteka uye inogona kushandiswa muindasitiri yechikafu. Imwe yakajairika application yesilicon carbide zvikamu ndeyesimba yekuisa chisimbiso tekinoroji uchishandisa friction bearings uye mechaniki zvisimbiso, semuenzaniso mumapombi uye madhiraivha masisitimu. Kuenzaniswa nesimbi, silicon carbide inogonesa mhinduro dzehupfumi nehupenyu hurefu hwematurusi kana ichishandiswa nehukasha, yakanyanya-tembiricha midhiya. Silicon carbide ceramics zvakare yakanakira kushandiswa mumamiriro ekuda muballistics, kugadzirwa kwemakemikari, simba tekinoroji, kugadzira mapepa uye senge pombi system zvikamu.
Reaction bonded silicon carbide, inozivikanwawo sesiliconized silicon carbide kana SiSiC, imhando yesilicon carbide iyo inogadzirwa nekemikari inoita pakati peporous carbon kana graphite ine silica yakanyungudutswa. Nekuda kwekusara pamusoro pematanho esilicon, reaction bonded silicon carbide inowanzonzi siliconized silicon carbide, kana chidimbu chayo SiSiC.
Kana yakachena silicon carbide inogadzirwa nekunyunguduka kwesilicon carbide poda, inowanzove ine zvisaririra zvemakemikari anonzi sintering aids, ayo anowedzerwa kutsigira sintering maitiro nekubvumira yakaderera sintering tembiricha. Iyi mhando yesilicon carbide inowanzonzi sintered silicon carbide, kana kupfupikiswa kuSSiC.
Iyo silicon carbide poda inowanikwa kubva kusilicon carbide inogadzirwa sezvinotsanangurwa muchinyorwa silicon carbide.
