Chromium boride pauta Talosaga:

O le Chromium diboride o se mea faʻapipiʻi ionic, ma le fausaga tioata hexagonal. Chromium diboride i le vevela atoatoa laʻititi 40K (tutusa ma le -233 ℃) o le a liua i se superconductor.
Ma o lona vevela galue moni e 20 ~ 30K. Ina ia ausia lenei vevela, e mafai ona tatou faʻaogaina le neon vai, vai hydrogen poʻo le pusaaisa tapuni tapuni e faʻauma ai le malulu.
Pe a faʻatusatusa i pisinisi o loʻo i ai nei e faʻaaoga ai le helium vai e faʻamafanafana ai le niobium alloy (4K), o nei metotia e sili atu ona faigofie ma taugofie. O le taimi lava e doped i le carbon poʻo isi mea leaga, magnesium diboride i totonu o se maneta, pe o loʻo i ai se pasi o loʻo iai nei, o le gafatia e faʻamautu ai le superconducting e pei o niobium alloys, pe sili atu foi.
