niobium pentoxide hmoov rau optical iav
Product Description
Niobium pentoxide hmoov yog cov khoom dawb los yog daj daj, tsis muaj ntxhiab tsw.Niobium pentoxide hmoov yog insoluble nyob rau hauv dej, tab sis soluble nyob rau hauv molten potassium hydroxide thiab poov tshuaj sulfate, raws li zoo raws li nyob rau hauv alkali hlau carbonates thiab hydroxides.Tsis tas li ntawd, nws kuj yog soluble hauv hydrofluoric acid thiab kub sulfuric acid.Nyob rau hauv tej yam kev mob tshwm sim, niobium pentoxide tuaj yeem hnov mob nrog sodium carbonate, sodium hydroxide, sulfur, carbon thiab lwm yam khoom.Thaum rhuab, niobium pentoxide tawg los ua niobium oxide.Niobium pentoxide hmoov yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, uas tuaj yeem siv los ua cov khoom siv siab purity lithium niobate ib leeg crystals, nrog rau kev npaj ntawm lwm cov high-purity oxides.Tsis tas li ntawd, nws tuaj yeem siv los ua kev tshawb fawb tshawb fawb reagent.
