In principle, all lamellar minerals may be used as barrier pigments, e.g., micaceous iron oxide [5.167]-[5.169], layer silicates (mica), linear polymeric silicates (wollas-tonite), and talc [5.170], However, untreated mica and talc are not very suitable because they are highly permeable to water [5.57]. The surface can be modified with, for example, silanes or titanates, to reduce water permeability and improve adhesion... 

Lead titanate PbTiOs. A yellow buff-colored pigment, which possesses good resistance to weather and chalking. Pale yellow solid insoluble in water. Its Sp gr is 7.52. Derivation interaction of oxides of lead and titanium at a high temperature. Contains lead sulfate and lead oxide as impurities. 

Potassium titanate fiber K20(Ti02) n. in wherein n = 4—7. Highly refined, single crystals, approximately 6 pm long by 0.1 p m in thickness, used as reinforcing fibers in thermoplastic composites. The fibers melt at 1370°C density is 3.2g/cm. They also act as white pigments.
