Lebenka kaarboonka silicate waxa iska leh refractory dhexdhexaad ah, kaas oo u adkaysta nabaad guurka aashitada iyo alkali slags, dareerayaasha, iyo daxalka kiimikada kale. Silicon carbide waxay leedahay astaamo awood sare leh, iska caabin wanaagsan oo ka-hortagga oksaydhka, iyo wax isbeddel ah oo heerkulka sare leh. Dhammaan alaabta ceeriin ee lebennada aan oksaydh-ku-soo-celinta lahayn, leben kaarboon slilica ah ayaa ah kan ugu dhaqaalaha badan oo loogu isticmaalka badan yahay meelaha qaarkood. kuwaas oo loo isticmaali karo warshado kala duwan, sida warshadaha dhagaxa, warshadaha dhalooyinka, warshadaha biraha, warshadaha daabacaadda, warshadaha iftiinka. Ka sokow, leben kaarboon Silica for sale leedahay wax qabad aad u fiican oo ku saabsan iska caabinta nabaad guurka deegaanka aad u xun, sida conductivity kulaylka sare, caabbinta abrasive wanaagsan, caabbinta shoogga kulaylka weyn, u adkaysta u acid iyo nabaad alkali slag iyo coefficient kulaylka hoose hooseeyo iyo iwm.
Qalabka cayriin ee silicate carbide block waa silikoon carbide, qiyaastii 72% -99%. Silicon carbide waxa kale oo loo yaqaan moissanite, ciid corundum ama ciid refractory. kaas oo ay sameeyaan ciid quartz, batroolka kookaha ama daamurka dhuxusha, iyo xawaashka alwaax, oo ay soo saaraan heerkul sare oo dhalaalay foornada iska caabinta korontada.
Leben carbide Silicon waxaa laga soo saaraa silikoon carbide, walxo cayriin ah oo lagu farsameeyay foornada koronto ee nooca caabbinta ah ee heerkulka ka sarreeya 2500 ° C, iyada oo loo marayo falcelinta silica leh kaarboon. Lebenka kaarboonka silcate waxay leeyihiin koror kuleyl toban jeer ka badan kuwa refractories fireclay, daxal wanaagsan iyo caabbinta shoogga kulaylka, waxaana loo samayn karaa qaabab adag. Leben kabo silica waxay u adkeysan kartaa weerarka dharbaaxada iyo nabaad guurka ololka.
Lebenka Silicon carbide refractory waxaa loo kala saari karaa lebenka carbide silikoon isku xidhan, Si3N4 leben carbide silicon bonded, leben carbide Sialon bonded, leben carbide bonded β-SiC bonded silikon carbide leben, Si2ON2 bonded silikon carbide leben iyo leben silikon carbide recrystal recrystal.
