1. Gịnị bụ seramiiki ájá?
A na-eme ájá seramiiki nke mineral nwere Al2O3 na SiO2 ma tinye ya na ihe ndị ọzọ ịnweta. Uzuzu ebe a na-egwupụta ahịhịa nke ntụ ntụ, pelletizing, sphering na usoro nhazi ọkwa mere. Ihe owuwu ya bụ kristal bụ Mullite na Corundum, nwere udi ọka gbara okirikiri, refractoriness dị elu, nkwụsi ike thermochemical dị mma, mgbasawanye ọkụ dị ala, mmetụta na nguzogide abrasion, njiri nke ikewa. Enwere ike iji ájá seramiiki mepụta nkedo dị elu site n'ụdị usoro nkedo ájá ọ bụla.
2. Ngwa ngwa nke ájá seramiiki
