Niobium (V) Chloride Powder Description
Niobium (V) chloride yog ib qho zoo heev dej soluble crystalline niobium qhov chaw siv tau tshaj chlorides. Cov tshuaj chloride tuaj yeem ua hluav taws xob thaum fused lossis yaj hauv dej. Cov ntaub ntawv chloride tuaj yeem decomposed los ntawm electrolysis rau chlorine gas thiab hlau. Lawv raug tsim los ntawm ntau yam txheej txheem chlorination uas tsawg kawg yog ib qho chlorine anion (Cl-) yog covalently bonded rau cov hlau los yog cation. Ultra siab purity thiab proprietary formulations yuav npaj tau. Cov tshuaj chloride ion tswj cov kua dej sib npaug thiab pH qib hauv cov txheej txheem metabolic. Lawv tuaj yeem tsim cov inorganic lossis organic compounds.
Niobium (V) chloride yog cov khoom siv feem ntau siv los npaj lwm cov niobium tebchaw. Nws yog dawb crystals nyob rau hauv chav tsev kub, thiab tig daj thaum rhuab mus rau 183 degree, thiab puv txiv kab ntxwv-liab thaum melted. Nws yooj yim hydrolyzed rau NbOCl3 thiab haus luam yeeb hauv huab cua.
Niobium (V) chloride yog lub ntsiab ua ntej rau alkoxides ntawm niobium, uas pom niche siv nyob rau hauv sol-gel ua. Nws kuj yog qhov ua ntej rau ntau lwm qhov chaw kuaj tshuaj reagents.
