2. Product Property
Non qualitative white powder. Non toxic, not soluble in water, soluble in smoking Sulphuric Acid, slightly soluble in boiling Hydrochloric Acid. Chemical property is stable, it'll reduce to Barium Sulfide when heat with carbon. It wont change color when meeting with hydrogen sulfide or toxic gas in the air.
3. product usage
It is widely used as filled object for powder coatings, industrial paints, enamels, leather industry, printing, dyeing industry, printing ink, plastically materials, and photosensitive papers, etc. It can be used quite successfully in adhesives, coatings and sealants.

Paper industry: it helps in sizing of paper at neutral and alkaline PH, thus improving paper quality (reducing spots and holes and improving sheet formation and strength) and sizing efficiency.

Textile industry: it is used for color fixing in Naphthol based dyes for cotton fabric.

Other Uses: leather tanning, lubricating compositions, fire retardants, decolorizing agent in petroleum, deodorizer, firming agent, dyeing mordant, foaming agent in firefighting foams, fireproofing cloth, catalyst, PH control, waterproofing concrete, aluminum compounds, zeolites etc.
