Tono paura Chromium boride:
Ko te Chromium diboride he pūhui katote, me te hanganga karaihe hexagonal. Chromium diboride i te pāmahana tino paku 40K (he rite ki te -233 ℃) ka huri hei superconductor.
Na tona pāmahana whakahaere tūturu ko 20 ~ 30K. Kia eke ki tenei pāmahana, ka taea e tatou te whakamahi haukura wai, hauwai wai, pouaka pouaka kati-hurihuri ranei hei whakaoti i te whakamahana.
Ka whakaritea ki te ahumahi o naianei e whakamahi ana i te helium wai hei whakamatao i te koranu niobium (4K), he ngawari ake, he ohanga hoki enei tikanga. I te wa ka pehia ki te waro, ki etahi atu poke ranei, konupora diboride i roto i te papa aukume, kei te haere ranei i naianei, ko te kaha ki te pupuri i te superconducting he rite ki nga koranu niobium, he pai ake ranei.
