He aha nā pae sintering ʻekolu o nā keramika alumina? ʻO ka sintering kahi hana nui o nā keramika alumina holoʻokoʻa i ka hana ʻana, a he nui nā loli like ʻole e hana ʻia ma mua a ma hope o ka sintering, e kālele ana ʻo Xiaobian ma nā pae sintering ʻekolu o nā keramika alumina:
ʻO ka mea mua, ma mua o ka sintering, ʻoi aku ka nui o ka kaohi ʻana i ka mahana ma kēia pae, no ka mea, ke hoʻomau nei ka piʻi ʻana o ka mahana, e emi pū ka embryo, akā ʻaʻole e loli nui ka ikaika a me ka nui, inā he microscopic, ʻaʻole e loli ka nui o ka palaoa, akā ʻoi aku ka maʻalahi o ka embryo i kēia pae i ka hanana haki, ʻO ke kumu nui no ka mea ua hoʻokuʻu loa ʻia ka mea hoʻopaʻa a me ka wai, no laila pono mākou e hoʻolohe i ka wikiwiki o ka piʻi ʻana o ka mahana.
ʻO ka lua, i ke kaʻina hana sintering, e loli ka mahana me ka liʻiliʻi o ka amplitude, e emi mālie ke kino o ka embryo, a e loli nui ka nui. ʻOiai ʻaʻohe loli maopopo i ka microscopic grain, ʻaʻole i hoʻopaʻa ʻia nā ʻāpana āpau, a e liʻiliʻi a liʻiliʻi nā pores āpau. Pēlā nō, no ka mea he loli ka nui o ke kino o ka embryo, no laila he mea maʻalahi ke ʻike ʻia ka deformation a me ka cracking.
ʻO ke kolu, ʻo ka hope loa, ma hope o ka sintering, e piʻi nui ka mahana, e loli nui ke kino o ka embryo a me ka nui, ʻoi aku ka maopopo o ka loli o ka palaoa i loko o ka micro, e liʻiliʻi nā pores, e hoʻokumu ʻia nā pores i hoʻokaʻawale ʻia he nui, akā e waiho mau ʻia kekahi mau pores ma luna o ka palaoa.
