Why do we us barite/ baryte in lithopone paint?

Barium sulfide is an important chemical made from barite. When it is mixed with zinc sulfate, a chemical reaction ensues that results in an intimate mixture of barium sulfate and zinc sulfide called lithopone, which serves as a white pigment. Lithopone was used extensively to make white paint, but its importance for that purpose declined greatly after the introduction of titanium dioxide pigments. Lithopone has also been used in floor coverings and textiles. Barium sulfide and zinc sulfate have also been used to treat wooden artifacts to give them a marble-like finish.

Applications

Lithopone is a commonly used superior white pigment which exists in the form of a white powder. Is insoluble in water, and does not react with hydrogen sulfide or alkalis. Lithopone decomposes in acids with the release of hydrogen sulfide. Long-term exposure to sunlight causes lithopone to discolor, but putting it in a dark place will cause it to revert to its original color. It is used as a raw material for paints and paint pigments. Heating barium sulfate with a reducing agent will form barium sulfide (BaS), which is then reacted with zinc sulfate (ZnSO4) to yield a mixture of barium sulfate and zinc sulfide (70% BaSO4, 30% ZnS), which is referred to as lithopone. Barite used to make lithopone must have a BaSO4 content greater than 95%, and may not contain any visible, colored impurities.

Communication with customers

A: Hello Tokusyo, are you the barite/baryte mine owner?

B: Yes dear, we are the barite mine owner, and our mines locate in Guizhou, China.

A: Can you provide 10,000tons of barite lump monthly.

B:Yes off cause, we can provide more than that number, it’s about 20,000tons monthly.

A:What is the packing condition of your barite/baryte lumps.

B: If your quantity is more than 3,000 tons, we can ship them through bulk loading, and if your quantity is less than 3,000 tons, we suggest the container lose loading.

A: What is your payment terms

B: T/T and LC is workable for us, so it is up to you.

A:How do you control your quality to make sure your product could meet our requirements.

B: We have various kinds of methods to control our quality. First of all, we have a full set of test machines in our factory such as specific gravity testing machines, particle size testing machine, and moisture testing and whiteness testing machine. And besides we work with the third party inspection institution SGS, we can arrange the inspection according to customers requirements before the product shipped. We can be 100% sure that we can delivery the right product to you hands.

A: that is perfect, and i can feel that you are very professional supplier and let’s try it.
