    Solubility: Soluble in water, solution is slight alkalinity. Insoluble in ethyl alcohol, slightly soluble in ammonia.

    APPLICATION
    Sodium Tungstate Dihydrate Image Sodium tungstate dehydrate is used as the raw material for tungstic acid, tungsten products and other tungstate, also mordant, coloring agent and catalyst. Also can be used as fire-proofing agent and analytical chemical agent.

    PROPERTY
    1.Follow the instruction to use and store so that it wont decompose. Heat it until 100℃ it will lose crystalline water become anhydride.
    2.Stable in the air, heat to 100℃ will become anhydrous salt.
    3.Encountered strong acid will decomposed into tungstic acid.
    4.Toxic. Get contact with tungsten compounds will stimulate the upper respiratory tract and deep respiratory tract. It also has irritation toward human's eyes and skin. During the operating process, making contact or inhalating will make people be general weakness, fever, rash, proteinuria.
