Nā Kumu Koʻikoʻi e Hoʻopilikia ana i ke Paʻa o nā Seramika Palekana

ʻO nā keramika alumina kahi ʻano mea keramika me ka alumina ma ke kino nui. ʻOi aku ka maikaʻi o ka conductivity o nā keramika alumina, ka waiwai mechanical, ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa wela kiʻekiʻe, i ʻike ʻia hoʻi he keramika kūikawā. ʻO ka mea keramika Al2O3 kahi ʻano hexagonal mānoanoa i haku ʻia me nā ion oxygen, a me nā ion alumini i hoʻopiha ʻia i ʻelua hapakolu o ka hakahaka octahedral, ʻo ia ka mea like me ke ʻano corundum kūlohelohe paʻa α-Al2O3, no laila he kiʻekiʻe ke kiko heheʻe o ka keramika, paʻakikī kiʻekiʻe, a he kūpaʻa ʻaʻahu maikaʻi loa. ʻO ka paʻakikī o ka keramika alumina ≥HRA85, ʻo ka paʻakikī ka lua o ka daimana, ʻoi aku ka maikaʻi o kona kūpaʻa ʻaʻahu.

Ma ke ʻano laulā, ua māhele ʻia ka alumini alumina seramika i ke ʻano maʻamau a me ke ʻano maʻemaʻe kiʻekiʻe. Ma muli o ka nui o Al2O3, ua māhele ʻia ke ʻano maʻamau i 92% alumina seramika, 95% alumina seramika, a me 96% alumina seramika. ʻO ke ʻano maʻemaʻe kiʻekiʻe he 99% alumina seramika a ma luna o ka seramika, ʻo kona mahana sintering he 1650-1990℃. Hiki ke hoʻohana ʻia nā seramika alumina maʻemaʻe kiʻekiʻe 99.7%-99.9% i ka ʻoihana uila e like me ka papa kaapuni i hoʻohui ʻia a me nā mea hoʻokaʻawale alapine kiʻekiʻe, ʻo ka ʻoihana semiconductor i ka wili ʻana i nā wafers silicon, a pēlā aku, ʻo ia ka sapphire a me ka semiconductor silicon wafer kemika mechanical polishing kī i nā ʻāpana kākoʻo a me nā mea hoʻopau.

ʻO ke kiʻekiʻe o ka ʻike alumina o nā keramika pale ʻaʻahu, ʻoi aku ka paʻa o ka hana, ʻo ia hoʻi, ʻo ke kiʻekiʻe o ka ʻike alumini, ʻoi aku ka maikaʻi o ka hana pale ʻaʻahu. ʻO nā keramika alumina ma ke ʻano he mea keramika holomua, me ka wikiwiki o ka hoʻomohala ʻana o nā mea pale ʻaʻahu ʻoihana hou, e hoʻohana nui ʻia i ka nohona hou.

Hāʻawi ʻo Chemshun Ceramics i nā ʻano keramika alumina maʻemaʻe like ʻole, e like me: 92%Al2O3 & 95%Al2O3 liner keramika alumina kū i ke ʻano maʻamau, nā ʻāpana lining keramika a me ka moena, tile keramika hexagon/square, paipu/tube/kuʻekuʻe keramika, cylinder keramika, poloka/cube keramika, piliki keramika, 99.7% papa kumu alumina a me ka papa poli wafer alumina, 99% keramika pale ʻūlū alumina, a pēlā aku.
