Ma'adanai na spinel suna da tasiri mai mahimmanci akan kayan zafi mai zafi na kayan haɓaka. Alal misali, saboda ƙananan haɓakaccen haɓakaccen haɓakar thermal na spinel (α = 8.9x10-* / ℃ a 100 ~ 900 ℃), ana amfani da spinel azaman wakili mai ɗaure (Ko kuma ana kiran lokaci cementing, matrix), tubalin magnesia-alumina tare da periclase. a matsayin babban lokaci na crystal, lokacin da yanayin zafi ya canza sosai, damuwa na ciki da aka haifar yana da ƙananan, kuma tubalin ba su da sauƙi don karyawa, don haka za'a iya inganta kwanciyar hankali na thermal tubalin (bulogin magnesia-alumina Ƙarfafawar thermal shine 50 ~ 150). sau).
Bugu da ƙari, saboda spinel yana da kyawawan kaddarorin irin su high taurin, barga sunadarai Properties, da kuma high narkewa batu, kuma yana da matukar juriya ga lalata ta daban-daban narke a yanayin zafi, kasancewar ma'adanai na spinel a cikin samfurori ya inganta High zafin jiki na aikin. samfur.
Babban dalilin da ya sa high-zazzabi load taushi zafin jiki na magnesia-alumina tubalin (farawa batu ne ba kasa da 1550-1580 ℃) ne mafi girma fiye da na Magnesia tubalin (farawa batu ne a kasa 1550 ℃) shi ne cewa matrix abun da ke ciki ne daban-daban. .
Don taƙaitawa, spinels sune kayan aiki masu kyau dangane da ma'anar narkewa, haɓakar thermal, taurin, da dai sauransu, tare da ingantattun sinadarai masu inganci, juriya mai ƙarfi ga yashwar alkaline slag, da juriya ga yashwar ƙarfe narkakkar .Comparison na kaddarorin spinel da sauran oxides. .
