Alumini caman-biriki bɛ tila ka kɛɲɛ ni alumina hakɛ ye: Jate III (Al2O3: 48–65%), Dakun filanan (Al2O3: 65–75%), Dakun fɔlɔ (Al2O3: 75–80%), ani Dakun kɛrɛnkɛrɛnnen (Al2O3: A ka bon walima a bɛ bɛn 80%) ma.
U bɛ tila ka kɛɲɛ ni foro suguya ye min bɛ kɛ: spalling-resistant high-alumina bricks for siman forow, low-creep high-alumina bricks for hot blast stoves, ani phosphate-bonded high-alumina bricks for rotary furns (minnu bɛ kɛ ka seramsite, litium oxide, walima zinc oxide dilan).
Ka da u cogoya n’u bonya kan, u ye biriki-cogo, sɔgɔlan-cogo, ani wedge-cogo birikiw ye, ka fara alumina skew birikiw kan minnu ka bon-ani ani ankɔri biriki.
Jatedenw fana bɛ birikiw la minnu bɛ kɛ ka kɛɲɛ ni sariya ye, biriki minnu dilannen don cogo la, ani biriki minnu dilannen don kɛrɛnkɛrɛnnenya la.
