Hale Hana Kina Bauxite no ke kūʻai aku
Bauxite
Nā kikoʻī:
ʻO ka Bauxite ka mea nui i hana ʻia me ka alumina, ʻo ia hoʻi ka alumina hydrated i loaʻa nā haumia, a he ʻano mineral lepo. Keʻokeʻo a keʻokeʻo paha, melemele ʻeleʻele a ʻulaʻula māmā paha ma muli o ka nui o ka hao. Density 3.45g/cm3me ka paʻakikī 1-3, opaque, brittle. Paʻakikī loa e hoʻoheheʻe. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o ka sulfuric acid a me ka sodium hydroxide solution. Hoʻohana nui ʻia no ka hoʻoheheʻe ʻana i ka alumini a me ka hana ʻana i nā mea refractory.
Ka Pōmaikaʻi o ka Huahana:
ʻOihana Refractory:
Ka mahana pale ahi a hiki i ka 17800C, paʻa ka waiwai kemika a me ka hana kino maikaʻi.
ʻO ke olonā pale ahi:
Loaʻa iā ia nā pono o ke kaumaha māmā, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa wela maikaʻi, ka conductivity wela haʻahaʻa, ka mana wela liʻiliʻi a me ke kūpaʻa haʻalulu mechanical.
