Babban halayensa shine sillimanite yana fuskantar canjin yanayin jujjuyawa a yanayin zafi mai zafi (1300-1500℃), tare da faɗaɗa girma mai matsakaici (2%-3%), wanda zai iya daidaita raguwar sintering na jikin bulo, yana sa jikin bulo ya yi kauri kuma ya fi rufewa. Rashin ƙarfinsa shine 1770-1830℃, wanda ya dace musamman ga yanayin aiki na matsakaici da zafi mai yawa tare da manyan canjin zafin jiki da lalata sinadarai, tare da kyakkyawan aiki mai kyau.
Rarraba Samfura:
1. Bulo na Sillimanite na yau da kullun:Sillimanite na halitta (Al₂O₃ 60%-62%) + bauxite/laka, sintering na gargajiya. Matsakaicin porosity, kyakkyawan girgizar zafi, ƙarancin farashi; don yanayin zafi mai yawa, yawan canjin zafin jiki (maƙogwaron murhu, kayan daki na murhu na yumbu).
2. Bulo Mai Tsabta Mai Girma:Tsarkakken sillimanite na halitta (Al₂O₃ 62%-65%), Fe₂O₃≤0.3%, 1580-1650℃ sintering. Ya fi kauri, ya fi juriya ga alkali/tsatsa; don ɗan tsatsa mai guba (wuraren murhu na gilashi, tanderun narkewa marasa ƙarfe).
3. Bulo Mai Haɗa Sillimanite-Mullite:Sillimanite + mullite, canjin yanayi mai ƙarfi + kwanciyar hankali mai zafi. Al₂O₃ 63%-68%, yana daidaita juriyar girgiza/raguwa ta zafi; don babban canjin yanayi, ɗaukar nauyi mai zafi (ƙasa da tanda mai ƙarfi, tashar kwararar gilashi).
Samfuran tubalin Sillimanite:Bulo mai tashar jiragen ruwa, magudanar ruwa, bututun juyawa, wurin ciyarwa, zoben sama, faifan motsawa, naushi, silinda mai ciyarwa, bulo mai toshe wuta, tubalin damper, tubalin baka, murfin wurin ciyarwa, tubalin rami, tubalin ƙona wuta, katako, tubalin murfin da sauran nau'ikan da ƙayyadaddun bayanai.
Babban Amfani:
1. Sauyin Mataki Mai Sauƙi:Faɗaɗa yawan zafin jiki yana rage raguwar raguwa, yana tabbatar da babban cikas da kyakkyawan rufewa.
2. Daidaitaccen Daidaitaccen Tsarin Zafi:Ƙarancin faɗaɗa zafi, kyakkyawan juriya ga girgiza/rashin ƙarfi na zafi, wanda ya dace da sauye-sauyen zafin jiki akai-akai.
3. Inganci Mai Tsada:Kayan da aka yi da sillimanite na halitta, mafi ƙarancin farashi fiye da tubalin mullite, ya dace da yanayi masu saurin kamuwa da farashi.
4. Kyakkyawan Juriyar Slag:Yana jure wa tsatsa/ruwa mai laushi da kuma lalacewar zafi mai yawa, ba shi da sauƙin cirewa.
5. Na Halitta & Mai Kyau ga Muhalli:Babu ƙazanta mai cutarwa, ƙarancin gurɓataccen abu, ya dace da murhun da ke da kyau ga muhalli.
