He aha nā ʻanuʻu sintering ʻokoʻa ʻekolu o nā seramika alumina? ʻO ka Sintering kahi hana nui o ka alumina seramics holoʻokoʻa i ka hana ʻana, a he nui nā hoʻololi like ʻole e hiki mai ma mua a ma hope o ka sintering, ʻo ka Xiaobian e pili ana i nā ʻano sintering ʻekolu o nā seramika alumina.
ʻO ka mea mua, ma mua o ka sintering, ʻoi aku ka nui o ka mālama ʻana i ka mahana ma kēia pae, no ka mea e piʻi mau ana 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 wā i ka haki ʻana, ʻo ka mea nui no ka hoʻokuʻu ʻia ʻana o 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 hoʻololi ka mahana i ka amplitude liʻiliʻi, e emi mālie ke kino embryo, a e loli nui ka density. ʻOiai ʻaʻohe hoʻololi ʻike ʻia o ka palaoa microscopic, ʻaʻole i hoʻopaʻa hou ʻia nā ʻāpana āpau, a e liʻiliʻi a liʻiliʻi nā pores holoʻokoʻa. Pēlā nō, no ka mea he loli ka leo o ke kino embryo, no laila ua maʻalahi ka ʻike ʻana i ka deformation a me ka haki ʻana.
ʻO ke kolu, ʻo ka hope, ma hope o ka sintering, e piʻi nui ka mahana, e hoʻololi nui ʻia ke kino embryo a me ka density, ʻoi aku ka maopopo o ka hoʻololi ʻana o ka palaoa i ka micro, e liʻiliʻi nā pores, ke kūkulu ʻia ʻana o nā pores kaʻawale, akā. e koe kekahi mau pores ma luna o ka palaoa.
