Hafnium ọla dị ọcha (Hf)

1. Ọdịdị na nkọwa:

Hafnium dị ọcha dị elu, nke a makwaara dị ka hafnium kristal, bụ kristal ọla ọcha na-acha ntụ ntụ nke nwere ọmarịcha ọla; Usoro kemịkalụ: Hf; Ibu ibu: 178.49 Njupụta: 13.31 g / cm3; Ebe na-agbaze: ihe dị ka 2227 ℃ Ebe esi mmiri: ihe dị ka 4602 ℃.

2. Ngwongwo:

Ọ nwere ezigbo nguzogide corrosion, ọ naghị adị mfe imebi site n'ozuzu acid na alkali aqueous ngwọta, na-adị mfe soluble na hydrofluoric acid na-etolite fluorine complexs. Na oke okpomọkụ, hafnium nwekwara ike jikọta ya na oxygen, nitrogen na gas ndị ọzọ iji mepụta oxides na nitrides; hafnium kwụsiri ike na ikuku, na hafnium ntụ ntụ dị mfe ọkụ; hafnium nwere nnukwu neutron na-ekpo ọkụ n'ofe akụkụ, na hafnium nwere ike nuklia a ma ama bụ ihe dị ụkọ dị mkpa maka mmepe nke ụlọ ọrụ ike atọm.
