Barium sulfate is extracted from mined barites, and undergoes grinding and classification to yield particles sizes suitable for use in coatings. As mentioned previously, barium sulfate has a higher specific gravity ( ρ = 4.5 g cm −3 ), and hence leads to higher specific gravity coatings, or lower coverage coatings (i.e., the coating covers a ...
