Mea Hana Keramika Hou (1)

ʻO nā mea seramika i hana ʻia e ka hoʻohana ʻana i nā hana kūikawā o nā seramika ma nā ʻano kino e like me ke kani, ke kukui, ka uila, ka magnetism, a me ka wela ua kapa ʻia nā seramika hana.Nui nā ʻano hana seramika me nā hoʻohana like ʻole.No ka laʻana, hiki ke hana ʻia nā mea uila e like me conductive ceramics, semiconductor ceramics, dielectric ceramics, insulating ceramics e like me ka ʻokoʻa i nā waiwai uila o nā ceramics, i hoʻohana ʻia e hana i nā capacitors, resistors, kiʻekiʻe-mehana a me nā mea kiʻekiʻe. ʻoihana uila, nā mea hoʻololi a me nā ʻāpana uila ʻē aʻe.

Semiconductor keramika

ʻO ka semiconductor ceramics e pili ana i ka poly crystalline ceramic material i hoʻokumu ʻia e ka ʻenehana seramika, me nā hiʻohiʻona semiconductor a me ka conductivity uila ma kahi o 10-6 ~ 105S/m.Hoʻololi nui ka conductivity o nā semiconductor ceramics ma muli o nā loli i nā kūlana o waho (ka wela, ka māmā, ke kahua uila, ka ea a me ka mahana, a me nā mea ʻē aʻe), no laila hiki ke hoʻololi ʻia ka nui o ke kino i loko o ke kaiapuni waho i nā hōʻailona uila e hana i nā ʻāpana koʻikoʻi no nā ʻano like ʻole. nā kumu.

Mea hoʻoheheʻe mākēneki

Ua kapa ʻia hoʻi nā seramika magnetic he ferries.ʻO kēia mau mea e pili ana i nā mea magnetic oxide i haku ʻia me nā ion hao, nā ion oxygen a me nā iona metala ʻē aʻe, a aia kekahi mau ʻokikene magnetic ʻaʻole i loko o ka hao.ʻO nā Ferries ka hapa nui o nā semiconductor, a ʻoi aku ka kiʻekiʻe o ko lākou pale ʻana ma mua o nā mea metala maʻamau, a loaʻa iā lākou ka pōmaikaʻi o nā poho liʻiliʻi eddy.Ma ke kahua o ke alapine kiʻekiʻe a me ka ʻenehana microwave, e like me ka ʻenehana radar, ka ʻenehana kamaʻilio, ka ʻenehana ākea, ka lolouila uila a pēlā aku, ua hoʻohana nui ʻia.

Kiʻekiʻe wela superconducting keramika

Superconducting oxide ceramics me ka wela ko'iko'i ki'eki'e.ʻOi aku ka nui o kona wela koʻikoʻi ma luna o ka ʻāina wela helium wai, a ua hoʻomohala ʻia ke ʻano aniani mai ka hale Dnepropetrovsk.ʻOi aku ka kiʻekiʻe o ka superconducting ceramics ma mua o nā metala.Mai ka holomua nui ʻana o ka noiʻi ʻana i nā ceramics superconducting i nā makahiki 1980, ua hoʻohuli nui ʻia ka noiʻi a me ka noi ʻana o nā mea seramika superconducting kiʻekiʻe.I kēia manawa, ke hoʻomohala nei ka noi ʻana o nā mea superconducting kiʻekiʻe i nā noi kiʻekiʻe, nā noi uila, a me ka diamagnetism.

ʻO nā Seramika hoʻopulapula

ʻIke ʻia hoʻi ʻo ka mea hana keramika.Hoʻohana ʻia e like me nā insulators like ʻole, insulating structural parts, band switch a capacitor support brackets, electronic component packaging shells, integrated circuit substrates and packaging shells, etc. kiʻekiʻe dielectric ikaika, corrosion kū'ē a me ka maikai mechanical waiwai.
