Ọ bụrụ na a na-eji ájá seramiiki dochie ájá olulu mmiri na-emepụta ihe nkedo, ọtụtụ nsogbu ndị a na-enwe na mmepụta nke furan resin na-edozi onwe ya nwere ike idozi nke ọma.
Aja seramiiki bụ ájá okirikiri nwere nnukwu refractoriness dabere na Al2O3. N'ozuzu, ọdịnaya alumina karịrị 60%, nke bụ ájá na-anọpụ iche. Ọ naghị emeghachi omume na resin furan na hardener, nke nwere ike belata oriri acid nke ọma ma melite ogo nkedo.
E jiri ya tụnyere ájá silica, ọ̀tụ̀tụ̀ resin na hardener agbakwunyere na ájá seramiiki na-ebelata nke ukwuu. Mgbe ọnụọgụ resin agbakwunyere na-ebelata site na 40%, ike nke ájá ịkpụzi ka dị elu karịa nke ájá silica. Ọ bụ ezie na ọnụ ahịa nkedo na-ebelata, a na-ebelata mmepụta gas site na ịkpụzi ájá ma ọ bụ isi, mmebi nke porosity na-ebelata nke ọma, àgwà nkedo na-eme ka ọ dịkwuo mma, na ọnụ ọgụgụ mkpụrụ na-abawanye.
Maka mweghachi nke ájá resin furan, ugbu a, mweghachi esemokwu na-ewu ewu na China. Silica ájá imegharị ihe na-anabata usoro n'ibu. N'oge usoro mmeghari ohuru, a ga-agbaji ya, nha nha nha nke aja nrụgharị ga-adịwanye mma, ọnụ ọgụgụ resin kwekọrọ na ya ga-abawanye ụba, na arụmọrụ ikuku nke ájá ịkpụzi ga-akawanye njọ. Agbanyeghị nha nke ájá ceramiiki ọ fọrọ nke nta ka ọ bụrụ na ọ nweghị mgbanwe ọ bụla site na usoro esemokwu n'ibu n'ime oge 40, nke nwere ike hụ na ịdị mma nke nkedo kwụsiri ike.
Na mgbakwunye, ájá silica bụ ájá polygonal. Na ịkpụzi imewe, a na-emepụta akụkụ akụkụ nke obere na ọkara nke ihe dịka 1%. Aja ceramic bụ okirikiri, na esemokwu ikwu ya pere mpe karịa ájá silica, yabụ enwere ike belata akụkụ ahụ ya, na-echekwa ọnụ ahịa igwe na-esote. Ọnụ ọgụgụ nkwụghachi nke ájá silica dị ala, ọnụego mgbake n'ozuzu bụ 90% ~ 95%, a na-emepụta ihe mkpofu siri ike karị, na enwere uzuzu dị ukwuu na gburugburu nkedo nke ogbako ahụ. Ọnụego nkwụghachi nke ájá seramiiki nwere ike iru karịa 98%, nke nwere ike ibelata mkpofu siri ike nke ọma ma mee ka ogbako mmepụta ahụ dịkwuo akwụkwọ ndụ akwụkwọ ndụ na ahụike.
Aja seramiiki nwere refractority dị elu, nso ọdịdị ọka okirikiri yana ezigbo mmiri. N'oge a na-emepụta ihe nkedo, n'ụzọ bụ isi, ọ dịghị ntụpọ ájá na-egbuke egbuke ga-eme, nke nwere ike ibelata ọrụ nke ihicha na ichicha nke ọma. Ọzọkwa, ọkwa ma ọ bụ ọnụ ọgụgụ mkpuchi nwere ike ibelata, na-ebelata ọnụ ahịa mmepụta nke nkedo.
