Modified barium sulphate is also divided into modified barium sulfate and Modified Precipitated barium sulfate. Barite powder or precipitated barium sulfate is treated to enhance its performance in a certain aspect. Its application is similar to precipitation, which mainly depends on its relevant performance. Among them, it is also called modified ultra-fine barium sulfate or modified ultra-fine precipitated barium sulfate after further processing and refinement. The price is higher than precipitated barium sulfate.
