钠tetraborate decahydrate硼砂decahydrate

Borax is both soft and light colorless translucent crystals or white crystalline powder. In the chemical composition, it is contains 10 water molecules, four sodium borate. Borax odorless, taste salty. Soluble in water, glycerine, slightly soluble in alcohol, aqueous solution weakly alkaline. Borax in the air can be slowly weathering, melting into a colorless glassy substance, when.SpecificationsIndex NameExecutive StandardFirst-class productSecond productNa2B4O7·10H2O%≥99.595.0Sodium Carbonate (Na2CO3)%≤0.100.20Insoluble matter in water%≤0.040.04Sodium Sulfate (Na2SO4)%≤0.20.2Sodium Chloride (NaCl)%≤0.030.05Iron (Fe)%≤0.0020.005Is also the manufacture of optical glass, enamel and enamel raw materials.
