Key Characteristics of Calcium Metal
-
Te rahi o te mau hu'ahu'a e te tufaraa: E ohipa rahi te rahi e te hoê â huru o te mau hu'ahu'a, te î o te tapo'iraa, e te mau huru matini e te tino o te tao'a hopea. I te rahiraa o te taime, e horoa te mau paura maitai a'e i te hoê vahi rahi a'e, e mea maitai te reira no te mau pahonoraa e te sintering, tera râ, e nehenehe atoa te reira e faarahi i te haaputuputuraa.
-
Fa'ahoro'ā: E nehenehe te mau paura metala e riro ei mea tumu (metala parau-ti'a) e aore râ,, no te fana'o i te mau huru mai te puai rahi a'e, te faaohiparaa e piti aore ra hau atu â mau metala, te patoiraa i te ino, e aore râ, te arata'iraa uira.
-
Hō'ē'a: Te mau hoho'a o te mau hu'ahu'a, mai te hoho'a ïa e tae atu i te mau hu'ahu'a ore e aore râ, i te mau hu'ahu'a. E horo'a te mau paura hu'ahu'a i te taheraa e te tapo'iraa maitai a'e, Noa'tu e, e mea au roa te mau paura no te mau tapo'iraa e te mau rave'a roro uira no to ratou vahi taa ê e to ratou vahi i ni'a i te fenua.
-
Te viivii ore: Ia au i te faaohiparaa, E nehenehe te mau paura metala e tamâ - maitai - hia no te faaore i te mau mea ino, Mea faufaa roa no te faaohipa i te mau ravea uira, i ni'a i te reva, e te mau ravea rapaauraa ma'i e nehenehe ai te viivii e haamǎta'u i te ohipa.
