Akwai nau’o’in tubalin da ke juyewa da yawa:

(1) Bisa ga mataki na refractoriness, shi za a iya raba zuwa: talakawa refractory bulo kayayyakin (1580 ~ 1770 ℃), ci-gaba refractory kayayyakin (1770 ~ 2000 ℃) da kuma na musamman refractory kayayyakin (sama 2000 ℃)

(2) Dangane da sifa da girmansa, ana iya raba shi zuwa: daidaitaccen nau’in, bulo mai siffa ta musamman, bulo mai siffa ta musamman, babban bulo mai siffa ta musamman, da samfuran musamman irin su dakin gwaje-gwaje da crucibles masana’antu, jita-jita, bututu.

(3) Bisa ga gyare-gyaren tsari, shi za a iya raba zuwa kashi: slurry simintin kayayyakin, roba gyare-gyaren kayayyakin, Semi-bushe guga man kayayyakin, tamped gyare-gyaren kayayyakin daga powdered ba filastik laka, kayayyakin jefa daga narkakkar kayan, da dai sauransu.

(4) Dangane da ma’adanai na sinadarai, ana iya raba shi zuwa: kayan siliki, kayan siliki na aluminum, kayan magnesia, kayan dolomite, kayan chromium, kayan carbon, kayan zirconium, da kayan haɓaka na musamman.

(5) Dangane da sifofin sinadarai, ana iya raba shi zuwa: tubalin acidic, tsaka tsaki da kuma tubalin alkaline.

(6) Bisa ga manufar, an raba shi zuwa: tubalin da za a yi amfani da shi don masana’antar karfe, bulo don masana’antar siminti, bulo don masana’antar gilashi, bulo don masana’antar ƙarfe mara ƙarfe, bulo don masana’antar wutar lantarki, da sauransu.

(7) Bisa ga samar da refractory tubalin, shi za a iya raba zuwa kashi: sintered samar, lantarki Fusion samar, precast simintin samar, fiber folding samar, da dai sauransu.
