Cov tshuaj formula yog Cu (NO3)2. Blue rhombic flake crystals. tooj liab nitrate muaj deliquescence. Oxygen tso tawm los ntawm decomposition ntawm 170 degree . Soluble hauv dej thiab ethanol, yuav luag insoluble hauv ethyl acetate. Cov kua dej aqueous ntawm 0.2mol/L muaj pH ntawm 4.0. Tus txheeb ze ntom ntom yog 2.05. Melting point 114.5 degree. tooj liab nitrate yog oxidizing thiab kub hnyiab thiab tawg thaum nws yog rhuab tiv thaiv thiab rubbed nrog carbon plua plav, sulfur los yog lwm yam combustible tshuaj.

Daim ntawv thov
1. Copper nitrate yog siv rau kev tsim khoom ntawm purer tooj liab oxide, thiab tseem yog cov khoom siv raw rau kev tsim khoom ntawm lwm cov tooj liab ntsev thiab tooj liab plating. Nws kuj yog siv los ua tshuaj tua kab. Siv raws li mordant, tooj liab catalyst, accelerant. Kev lag luam enamel yog siv los ua cov xim. Nws kuj tseem siv rau hauv kev lag luam xim rau kev tsim cov pigments inorganic. Siv los ua cov xim pleev xim, kuj siv rau tooj liab plating, tooj liab oxide thiab tshuaj tua kab siv los ua tshuaj ntsuam xyuas thiab oxidants.
2. Copper nitrate tuaj yeem siv los ua cov xim rau cov ceramics, los tsim cov purity siab tooj liab oxide, tooj liab carbonate, tooj liab catalyst. Nws tuaj yeem siv los ua cov khoom siv raw rau cov ntaub ntawv photoresistor, phosphor activators, thiab tseem ua electroplating thiab tshuaj reagents.
3. Siv los ua cov tshuaj analytical reagents, oxidants, nitrification agents, catalysts thiab phosphor activators thiab photoresistive cov ntaub ntawv, rau daim duab tube ntau lawm thiab tooj liab plating.
4. Copper nitrate tuaj yeem siv los ua cov khoom siv rau electroplating tooj liab, thiab tseem tuaj yeem siv los ua ib qho ntxiv rau tshuaj polishing ntawm txhuas thiab alloys. Nws kuj yog feem ntau siv nyob rau hauv etching ntawm steel.
