SUOYI Haʻahaʻa Haʻahaʻa Alumina Porcelain Pauka Al2O3 Pauka

ʻO ka alumina he oxide paʻa o ka alumini me ke ʻano kemika Al2O3. Ua kapa ʻia ʻo ia he bauxite i ka mining, ceramics a me nā ʻepekema waiwai. Pono: Paʻa keʻokeʻo paʻakikī e hoʻoheheʻe ʻia i ka wai, ʻaʻala ʻole, ʻono ʻole, paʻakikī loa, ʻae maʻalahi i ka makū akā ʻaʻole deliquesce (ʻaʻole ia e komo i ka wai ma hope o ke puhi ʻana). ʻO ka alumini oxide kahi amphoteric oxide maʻamau (he ʻano α ka corundum a no ka hoʻopili kokoke loa hexagonal. Hiki ke hoʻoheheʻe ʻia i loko o nā ʻakika inorganic a me nā hopena alkaline, a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai. A me ka non-polar organic solvents; pili pili (d204) 4.0; helu hehee 2050°C. E mālama: E mālama i loko o kahi pahu i hoʻopaʻa ʻia a maloʻo. Hoʻohana: Hoʻohana ʻia e like me nā reagents analytical, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, maka kumu no ka hoʻoheheʻe ʻana i ka aluminika, a me nā mea refractory.
