Niobium poda
Niobium Powder (CASN. Zvinotora pane blusish tint painoratidzwa nemhepo pamhepo tembiricha yekuwedzera kwenguva. Niobium isingawanzo, yakapfava, inokanganisa, ductile, grey-chena simbi. Iyo ine muviri-cated cubic cubstalline chimiro uye mune yayo yemuviri uye yemakemikari zvivakwa zvakafanana neTantalum. Iyo yesimbi yesimbi mumhepo inotanga muna 200 ° C. Niobium, kana ichishandiswa mukukara, inovandudza simba. Zvivakwa zvaro zveSuplicationive zvinokurudzirwa kana wakasanganiswa neZirconium. Niobium Micron Powder anozviwana mune dzakasiyana-siyana maAccualies akadai semagetsi, alloy-kugadzira, uye zvekurapa nekuda kwemakemikari ayo anodiwa, zvimiro zvemagetsi, uye zvemagetsi zvemagetsi.
