barium sulphate is soluble in water

Rutile, one of the two common natural forms of TiO2, possesses a tetragonal crystal structure that imparts it with superior chemical stability and excellent optical properties. Unlike its anatase counterpart, rutile TiO2 exhibits greater hardness and density, making it more resistant to discoloration and corrosion. This durability makes rutile particularly suitable for outdoor applications where exposure to environmental factors is inevitable.
