ʻO pōhaku lepo alumina

Hōʻike Pōkole:

ʻO ka pōhaku alumina Oe kekahi o nā meahana hoʻōla ikehuola hoʻōla ikaika. Hoʻohana ia i nā ʻāpana hollow alumina e like me nā mea maka maka a hoʻohui pū me nā mea hoʻopaʻa e kī i nā ʻāpana hollow alumina i kahi umu wela kiʻekiʻe ma 1750 ℃. Loaʻa i nā pōhaku alumina Oe i nā ʻano o ka conductivity mehana haʻahaʻa, mālama maikaʻi ʻana i ka wela, ikaika ikaika compressive kiʻekiʻe, a hiki ke hana ma nā mahana ma lalo o 1800 ° C. Loaʻa iā ia ke kūpaʻa wela maikaʻi a me nā waiwai hoʻoweliweli wela, a me ka mālama ʻana i ka ikehu maikaʻi loa.
