Aia ka ʻāpana Al2O3 ma kahi o 30% ~ 45% o ka silica, a ʻoi aku ka haʻahaʻa o ka silica ma mua o 78%. No nā mea pale ʻakika nāwaliwali nā piliki pale ʻakika. Kūʻē ka poloka pale ʻakika i ka ʻōpala waikawa a me ka ʻino ʻana o nā kinoea waikawa, akā ʻaʻole maikaʻi loa ko lākou kūpaʻa alkali. He maikaʻi ka hana wela o nā poloka pale ʻakika a maikaʻi ke kūpaʻa ʻana i ka haʻalulu wela.
Nā Waiwai o nā Brick Fire Piʻo
- Kiʻekiʻe ka refractoriness,
- Kū'ē maika'i i ka palaho,
- Kū'ē maika'i i ka ha'alulu wela,
- Ikaika mīkini kiʻekiʻe,
- Haʻahaʻa ka nui o ke kolo ʻana o ka mahana kiʻekiʻe,
- ʻO ke kūpaʻa maikaʻi ʻana i ka spalling a me ke kūpaʻa ʻana i ka ʻaʻahu.
