Abstract: The embodiments relate to titanate crystal particle dispersions, methods of making the dispersions, and compositions and uses thereof. The dispersions and compositions containing the dispersions provide a high coverage to the skin and high near infrared/infrared (NIR/IR) reflectance. The dispersions include optionally surface treated titanate crystals used as cosmetic powders, and a cosmetically acceptable dispersing medium. The dispersions may be useful in cosmetic compositions as a foundation and/or as a composition to correct skin discoloration, and may be used protect the skin from sun exposure.

Abstract: A method for adsorbing radioactive material includes contacting a titanate represented by a chemical formula M2Ti2O5, where M is a univalent cation, with a radioactive material.

Abstract: A radioactive material adsorbent having large adsorption capacity is provided. The radioactive material adsorbent contains a titanate represented by a chemical formula M2Ti2O5 (M: univalent cation). The M2Ti2O5 has a large cation exchange capacity, exhibits thermal stability, exhibits excellent chemical resistance to acids, alkalis, and the like and, therefore is suitable for an adsorbent for a water treatment. The mechanical strength is improved by adding a binder to this titanate and performing forming and firing, so that pulverization due to vibration, impact, and the like applied during transportation and the like, and falling off of primary particles at the time of putting into water can be reduced.

Abstract: Radioactive strontium is efficiently removed from wastewater containing radioactive strontium. In a treatment method for radioactive strontium-containing wastewater, wastewater containing radioactive strontium and a powdery alkali metal titanate are mixed in a stirrer-equipped reaction tank by stirring such that radioactive strontium in the wastewater is adsorbed on the powdery alkali metal titanate, followed by subjecting the powdery alkali metal titanate having radioactive strontium adsorbed thereon to solid-liquid separation. The radiation dose of treated water can be effectively reduced in such a manner that a powder of an alkali metal titanate is directly added to radioactive strontium-containing wastewater and is dispersed therein and therefore radioactive strontium is efficiently removed by adsorption.
