1. He aha ke one seramika?
Hana ʻia ke one ceramic me nā minerala i loaʻa iā Al2O3 a me SiO2 a hoʻohui pū ʻia me nā mea mineral ʻē aʻe.He one spherical foundry i hana ʻia e ka pauka, pelletizing, sintering a me ka grading.ʻO kāna ʻano kristal nui ʻo Mullite a me Corundum, me ke ʻano o ka palaoa pōʻai, ka refractoriness kiʻekiʻe, ka paʻa thermochemical maikaʻi, ka hoʻonui haʻahaʻa haʻahaʻa, ka hopena a me ke kūpaʻa abrasion, nā hiʻohiʻona o ka fragmentation ikaika.Hiki ke hoʻohana ʻia ke one seramika e hana i nā hoʻoheheʻe kiʻekiʻe e nā ʻano hana hoʻolei one.
2. Wahi noi o ke one seramika
Ua hoʻohana nui ʻia ke one keramika i loko o nā hale ʻike o nā ʻano ʻenehana foundry, e like me ke one i uhi ʻia i ka resin, ke kaʻina hana paʻakikī ponoʻī (F NB, APNB a me Pep-set), pahu anuanu, pahu wela, ke one paʻi 3D, a me ke kaʻina hana foam nalowale. .
3. ʻO ke kikoʻī o ke one keramika
Hiki iā SND ke hāʻawi i ke one keramika o nā kikoʻī like ʻole.No ka haku mele ʻana, aia nā one alumini-oxide kiʻekiʻe, nā one alumini-oxide haʻahaʻa a me nā one alumini-oxide haʻahaʻa, e hoʻohana ana i nā mea hoʻoheheʻe like ʻole.Loaʻa i nā mea a pau ka puʻupuʻu ākea ākea e hoʻokō i nā koi o ka mea kūʻai.
4. Nā waiwai o ke one keramika
5. Puunaue ka nui o ka ʻāpana

6. ʻO ke ʻano o ke one hoʻokumu
ʻElua ʻano o ka one foundry i hoʻohana nui ʻia, ʻo ke one maoli a me ke one.
ʻO nā one foundry maʻamau ʻo ke one silica, ke one chromite, olivine, zircon, ke one ceramic a me nā cerabeads.ʻO ke one ceramic a me nā cerabeads he one artificial, ʻo nā mea ʻē aʻe he one kūlohelohe.
7. ʻO ka refractoriness o ka one foundry kaulana
Ke one silica: 1713 ℃
ʻO ke one keramika: ≥1800 ℃
Ke one Chromite: 1900 ℃
ʻOlivine one: 1700-1800 ℃
Ke one Zircon: 2430 ℃
