He āhuatanga whai hua te nikara parakore, te nikara iti-koranu rānei, i roto i ētahi mara, inā koa te tukatuka matū me te hikohiko. He tino ātete te nikara parakore ki ngā matū whakaiti maha, ā, kāore i te tino pai te ātete ki ngā kawakawa caustic. Ki te whakatauritea ki ngā koranu nikara, he nui te kawe hiko me te kawe wera o te nikara parakore arumoni. He teitei hoki te pāmahana Curie me ngā āhuatanga aukume pai. He iti te pakeke o te nikara kua whakawerahia, ā, he pai te ngāwari me te ngāwari ki te whakakorikori. Ko aua āhuatanga, me te pai o te ngāwari ki te whakarewa, ka tino taea te hanga i te konganuku. He iti te tere whakapakeketanga o te nikara parakore, engari ka taea te mahi matao ki ngā taumata kaha teitei me te pupuri tonu i te ngāwari.Nikara 200meNikara 201e wātea ana.

Ko te Nikara 200 (UNS N02200 / W. Nr. 2.4060 me 2.4066 / N6) he nikara parakore ā-pākihi (99.6%). He pai ōna āhuatanga miihini, ā, he tino ātete ki ngā taiao waikura maha. Ko ētahi atu āhuatanga whai hua o te koranu ko ōna āhuatanga aukume me te aukati aukume, te kawe wera me te hiko teitei, te iti o te ihirangi hau me te iti o te pēhanga kohu. Kei te Ripanga 1 te hanganga matū. Nā te ātete waikura o te Nikara 200 e tino whai hua ai mō te pupuri i te parakore o te hua i roto i te whakahaere i ngā kai, ngā muka hangai, me ngā kawakawa caustic; me ngā tono hanganga hoki e whakaarohia nuitia ana te ātete ki te waikura. Ko ētahi atu tono ko ngā pūwero kaipuke matū, ngā wāhanga hiko me te hiko, ngā wāhanga rererangi me ngā wāhanga pere.
