ʻO ka pōʻaleʻa alumina ka mea wili o ka hale wili pōpē, nā lako wili ipu

ʻO ka mea nui o ka Alumina Ceramic Ball he alumina, i hoʻokumu ʻia e ka ʻōwili ʻana a me ka ʻenehana kaomi isostatic i loko o ka pōleʻa a calcined ma 1600 degere Celsius. ʻO kona mau hiʻohiʻona: ke kiʻekiʻe kiʻekiʻe, ka lole haʻahaʻa, ke kūpaʻa ʻana, ka pale ʻana i ka hopena, ke kūpaʻa seismic maikaʻi, ka waikawa a me ke kūpaʻa alkali, ʻaʻohe pollution, hoʻomaikaʻi i ka hana wili, hoʻemi i ke kumukūʻai o ka hoʻohana.
