At present, barium sulfate powder materials on the market mainly include natural barium sulfate and precipitated barium sulfate. Natural barium sulfate is obtained by directly grinding barite, precipitating barium sulfate and chemical synthesis precipitation. What is the difference between the two? Let me tell you the secret.

1. Prices vary greatly.

It can be seen from the production process that the production costs of the two products are very different, and the output is also different. The production process of natural barium is simple and the output is large, so the relative price is relatively low. The total price of natural barium is about 1500 yuan/ton. Precipitated barium sulfate is produced through a series of complex processes such as calcination, synthesis, extraction, precipitation, flash evaporation, etc. It consumes a lot of raw materials, such as electricity, coal, sodium sulfate, barite, etc. The daily output is limited and the cost is much higher than that of natural barium. At present, there are only more than 10 domestic manufacturers that can only produce precipitated barium sulfate. Qinba Salt has been specialized in producing precipitated barium sulfate for 15 years, with mature and stable process and stable quality of precipitated barium sulfate. There are more than 1000 domestic customers.

2. The content of barium sulfate varies greatly.

According to the source and mining area of barite, the main content of natural barium is very unstable, containing a lot of impurities, and the content of barium sulfate is generally less than 80%. When precipitated barium sulfate is not used, many impurities are removed by chemical synthesis. After extraction and precipitation, the content of barium sulfate can reach 99%, which can be used as filler for various fine chemical products, such as water-based coatings, automotive coatings, electronic ink and other high-end applications.

3. There is a large gap in product fineness.

In the powder industry, there is a unit for measuring product fineness called "AIM". The more things, the less refined. Therefore, there are 300~12500 meshes of barium sulfate on the market at present, of which 300 meshes are mainly natural barium sulfate, and the precipitated barium sulfate is generally more than 10000 meshes.

4. Different fields of application.

Natural barium sulfate is usually used for low content, fineness, PH value, dispersibility, whiteness, oil absorption and other indicators, such as ordinary coatings and ordinary plastics. Precipitated barium sulfate can be used as filler for various fine chemical products, such as water-based coatings, automotive coatings, electronic ink and other high-end applications.

In addition to the above differences, the product parameters of natural barium sulfate are much worse than those of precipitated barium sulfate, which will not be listed here.
