14.9. 1 Kev Taw Qhia. Ib chav kawm tshiab ntawm cov khoom siv superconducting, cov tooj liab oxides siab (feem ntau hu ua cuprates), tau tshawb pom los ntawm Bednroz thiab Muller hauv xyoo 1986.
cuprous oxide yog dab tsi?
Copper(I) oxide los yog cuprous oxide yog cov inorganic compound nrog formula Cu2O. Nws yog ib qho tseem ceeb oxides ntawm tooj liab, lwm yam yog tooj liab (II) oxide los yog cupric oxide (CuO). Cov khoom xim liab no yog ib feem ntawm qee cov xim pleev xim.
cuprous oxide tsim li cas?
Nws tuaj yeem tsim los ntawm cua sov tooj liab hauv huab cua ntawm thaj tsam 300–800 ° C: 2 Cu + O2 → 2 CuO Rau kev sim siv, ntshiab tooj liab (II) oxide yog npaj zoo dua los ntawm cua sov tooj liab (II) nitrate, tooj liab (II) hydroxide, los yog tooj liab (II) carbonate: 2 Cu(NO3)2(s) → 2 CuO (s) + 4 NO2 (g) + O2( g) (180°C)
cuprous oxide siv rau dab tsi?
valences: cuprous oxide, Cu2O, thiab cupric oxide, CuO. Cuprous oxide, cov khoom siv crystalline liab, tuaj yeem tsim los ntawm electrolytic lossis rauv txoj kev. Nws raug txo kom yooj yim los ntawm hydrogen, carbon monoxide, charcoal, lossis hlau rau hlau tooj liab. Nws muab cov xim liab rau iav thiab siv rau cov xim pleev xim rau
Puas muaj cuo2?
tooj liab oxides muaj nyob rau hauv ob hom: cupric oxide (CuO) thiab cuprous oxide (Cu2O), nyob ntawm lub xeev valence ntawm tooj.
