ʻO nā seramika alumina
1. Ka paakiki kiekie
ʻO ka paʻakikī ʻo Rockwell ʻo HRA80-90, ʻoi aku ka paʻakikī ma mua o ke daimana, ʻoi aku ka nui ma mua o ke kūpaʻa ʻana o ke kila a me ke kila kila.
2. Kūleʻa maikaʻi i ka ʻaʻahu
Ana ʻia e nā ʻoihana noiʻi ʻoihana, ʻo kona kūpaʻa ʻaʻahu e like me 266 mau manawa o ke kila manganese. He 171.5 mau manawa, e like me kā mākou mau makahiki he ʻumi o ka nānā ʻana i ka mea kūʻai aku, ma lalo o nā kūlana hana like, hiki ke hoʻolōʻihi i ke ola lawelawe o nā mea hana ma kahi o ʻumi mau manawa.
3. Ke kaumaha māmā
ʻO kona mānoanoa o 3.5g/cm3 he hapalua wale nō ia o ke kila, hiki ke hoʻemi nui i ka ukana.
Nā hiʻohiʻona:
Kiʻekiʻe mikaika echanical
ʻO ka resistivity kiʻekiʻe a me ka insulation maikaʻi
ʻO ka paʻakikī Mohs o 9 a me ke kūpaʻa maikaʻi loa
Kiʻekiʻe heheʻe helu a me ka corrosion kū'ē
Maikaʻi spākaukau
ʻO nā waiwai opi
Ionic conductivity
ʻOihana noi: Mīkini, uila, kemika, petroleum etc.
Hoʻohana kikoʻī: ʻO ka substrate ceramic uila, plunger, sealing ring etc.
