- Applicable Processes
- Application
- Petroleum : The circulating mud weighting agent in the rotary drilling of oil and gas wells cools the drill bit, removes the cutting debris, lubricates the drill pipe, seals the hole wall, controls the oil and gas pressure, and prevents the oil well from spontaneous blowout.
- Chemical Industry: production of various barium compounds such as barium carbonate, barium chloride, barium sulfate, lithopone, barium hydroxide, and barium oxide.
- Filler : In the aspect of paint , it can also be added as an extender pigment to the paint, which can improve the covering and compactness of the paint and film. Improve the performance of the coating to a certain extent.
