ʻO Semiconductor e hoʻohana ana i ka lima ʻeleʻele alumina seramika

Semiconductor e hoʻohana ana i ka lima alumina ʻeleʻele ʻeleʻele i hoʻohana ʻia i ke kiʻi

ʻO ka wehewehe pōkole:

ʻO ke kūpaʻa ʻana o nā seramika alumina e like me ka corundum, hiki i ka pae paʻakikī Mohs 9, a ua hoʻohālikelike ʻia ke kūpaʻa ʻaʻahu me nā alloys superhard.ʻO ka pale wela o nā alumina ceramics nā hiʻohiʻona o ka liʻiliʻi thermal expansion coefficient, ka ikaika mechanical kiʻekiʻe a me ka conductivity thermal maikaʻi.Ma ka manawa like, hoʻohana nui ʻia ka alumina i nā ʻāpana mechanical i hoʻohana ʻia ma lalo o nā kūlana wela kiʻekiʻe ma muli o kāna hana kiʻekiʻe kiʻekiʻe (a hiki i 1700 ℃).

ʻO nā seramika alumina

1. Paʻa kiʻekiʻe

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. Kaumaha māmā

ʻO kona mānoanoa o 3.5g/cm3 he hapalua wale nō ia o ke kila, hiki ke hoʻemi nui i ka ukana.
