Amorphous refractory fiber
Aluminum silicate fiber tare da Al2O3 abun ciki na 45 ~ 60%.Ana shirya ta ta hanyar kashe narkakken ruwa mai zafi a cikin tsarin fibrosis, kuma yana cikin tsarin gilashin amorphous.Fiber da aka yi daga albarkatun ƙasa (kamar kaolin ko yumbu mai jujjuyawa) ana kiransa fiber na silicate na al'ada na al'ada (duba adadi);Fiber da aka yi daga alumina mai tsabta da silicon oxide ana kiransa fiber mai tsaftar silicate mai tsafta;Aluminum silicate fiber dauke da chromium an kara da kusan 5% chromium oxide;Abun cikin Al2O3 na kusan 60% ana kiransa fiber-alumina fiber.
Akwai hanyoyi guda biyu don kera zaruruwan amorphous refractory, wato, hanyar busa da hanyar kadi, waɗanda ake kira hanyar narkewa tare.Hanyar allura ita ce ta narke ɗanyen abu a cikin tanderun baka na lantarki ko tanderun juriya sama da 2000 ℃, sannan a yi amfani da matsewar iska ko tururi mai zafi don fesa ruwan narkakkar don samar da zaruruwa.Hanyar jifan waya ita ce a sauke ruwan rafi da aka narkar da shi a kan jujjuyawar matakai da yawa kuma a juya shi zuwa fiber ta hanyar centrifugal ƙarfi.
