Teknụzụ - Okwu Mmalite nke mkpuchi Zirconia

Zirconia bụ ọcha dị arọ amorphous ntụ ntụ ma ọ bụ kristal monoclinic, enweghị isi, enweghị ụtọ, ọ fọrọ nke nta ka ọ ghara ịsacha ya na mmiri.Ebe na-agbaze bụ ihe dịka 2700 ℃, yana ebe mgbaze dị elu na ebe esi mmiri, ike na ike, na okpomọkụ nkịtị dị ka ihe mkpuchi, na elu okpomọkụ nwere ihe magburu onwe ya dị ka eletriki conductivity.Ke adianade do, kemịkalụ Njirimara nke zirconia bụ nnọọ ike, insoluble na mmiri, hydrochloric acid na itughari sulfuric acid, nwere ezigbo thermochemical nkwụsi ike, elu okpomọkụ conductivity na elu okpomọkụ ike na siri ike, n'otu oge ahụ nwere ezi n'ibu, thermal, eletriki. ngwa anya Njirimara.
