Ihe e ji mara nke atomiki akpụkpọ anụ cathode bụ ịgbanye obere oyi akwa nke metal ọzọ n'elu otu ígwè, bụ nke a na-ebunye nke ọma na metal ala. Nke a na-etolite okpukpu abụọ nke nwere ụgwọ dị mma n'èzí, na ọkụ eletrik nke okpukpu abụọ a nwere ike mee ka mmegharị nke electrons dị n'ime ala metal kwupụta n'elu, si otú ahụ belata ọrụ mgbapụ nke electron nke isi metal ma na-amụba ikike ikuku electron ya. site na otutu oge. A na-akpọ elu elu a elu mmalite. Isi ihe eji dị ka matrix ọla bụtungsten, molybdenum, nanickel.
Usoro nhazi nke elu arụ ọrụ bụ n'ozuzu ntụ ntụ metallurgy. Tinye ụfọdụ oxide nke metal ọzọ nwere obere electronegativity karịa metal ntọala na metal ntọala, ma mee ka ọ bụrụ cathode site na usoro nhazi ụfọdụ. Mgbe cathode a na-ekpo ọkụ n'okpuru oghere na okpomọkụ dị elu, a na-ebelata oxide metal site na isi metal ka ọ bụrụ ígwè. N'otu oge ahụ, na-arụ ọrụ metal atọm n'elu na-ebelata ngwa ngwa evaporate na elu okpomọkụ, mgbe arụ ọrụ metal atọm n'ime nọgidere na-agbasa n'elu site ọka ókè nke isi metal ka gbakwunyere.
