ʻO ka ipu wili honua Corundum

HOʻOLAUNA: ʻo ka inoa o ka corundum, mai India mai, he inoa mineralogical me kona pūnana paʻakikī i ka daimana. Hoʻohana nui ʻia ʻo Corundum no ka wili ʻana i nā mea holomua. ʻO ka ʻōmole Corundum me nā pōpō zirconia. ʻo ia ke ala kūpono loa no ke kūpaʻa ʻana i ke komo ʻana. ʻOiai he paʻakikī ikaika ka corundum, he palupalu hoʻi ia, e ʻoluʻolu e pale i ka hāʻule ʻana i ka honua a me ka hopena ikaika kiʻekiʻe i ka wā e hoʻohana ai. Hiki iā mākou ke hoʻopilikino i nā ʻano ʻōmole vacuum like ʻole e like me nā pono o ka mea kūʻai aku.

ʻO nā hana kumu o nā ipu hoʻoheheʻe keramika alumina pololei Arc:
Inoa: nā ipu hoʻoheheʻe alumina pololei
Ka Hoʻohui Kemika Al2O3 ≥ 99
R2O ≤ 0.2
Fe2O3 ≤ 0.1
SiO2 ≤ 0.2
Ka nui o ka leo (g/cm2) ≥ 3.80
Ka porosity i ʻike ʻia (%) <1
Ikaika kūlou (Mpa)> 350
Ikaika hoʻopaʻa (Mpa)> 12000
ʻO ke kūpaʻa dielectric Σ (1MHz) 2
ʻO ka mahana hana kiʻekiʻe loa (°C) 1800
ʻO ka ipu kālua maikaʻi loa no ka hana ʻana i ka pauka TV, nā mea honua laha ʻole, nā metala makamae, a me ka kālua ʻana i nā capacitors seramika kiʻekiʻe, waena a me ka haʻahaʻa, NTC, PTC piezoelectric seramika a me ka lithium cobalt oxide, lithium manganese oxide pauka.

1. Maʻemaʻe kiʻekiʻe: Al2O3> 99%, kūpaʻa maikaʻi i ka pala kemika.
2. Hoʻomanawanui maikaʻi i ka mahana, hoʻohana lōʻihi ma 1600 °C, 1800 °C manawa pōkole.
3. Kū'ē maikaʻi i ka haʻalulu wela wikiwiki, ʻaʻole maʻalahi e pahū.
4. Hoʻolei paheʻe me ka mānoanoa kiʻekiʻe.
