Rare earth metal compounds, particularly lanthanum, cerium, and yttrium, are formed as porous particles and are effective in binding metals, metal ions, and phosphate. A method of making the particles and a method of using the particles is disclosed. The particles may be used in the gastrointestinal tract or the bloodstream to remove phosphate or to treat hyperphosphatemia in mammals. The particles may also be used to remove metals from fluids such as water.

The present invention provides a novel manufacturing process for producing a high surface area USP grade titanium dioxide in the nano-anatase form. In a manufacturing method aspect of the present invention, a process of producing a high surface area USP grade TiOnano-anatase base is provided. The method involves steps of: a) phosphorus doping of the titanium hydrate obtained in hydrolysis of a titanium compound; b) drying and calcination of the doped paste, thereby producing a high surface area USP grade titanium dioxide in the anatase crystal form with nano-particles suitable for UV screens and cosmetics.

Process for manufacturing of high surface area USP grade nano-anatase base

A process to produce mixed metal oxides and metal oxide compounds. The process includes evaporating a feed solution that contains at least two metal salts to form an intermediate. The evaporation is conducted at a temperature above the boiling point of the feed solution but below the temperature where there is significant crystal growth or below the calcination temperature of the intermediate. The intermediate is calcined, optionally in the presence of an oxidizing agent, to form the desired oxides. The calcined material can be milled and dispersed to yield individual particles of controllable size and narrow size distribution.

The invention concerns a process for producing a spinel compound of formula LiTiO, comprising a step of preparing a mixture of an organo-lithium compound selected from lithium alcoholates with an organo-titanium compound selected from titanic acid esters, in a liquid medium, and a step of hydrolyzing the mixture of said compounds. The invention also concerns a LiTiOparticulate material which may be produced according to the previous cited process and which has a BET surface area of at least 10 m/g. The material is particularly useful in the manufacture of Lithium Ion batteries.

A process is provided for making lithium titanate of closely controlled particle size in the range 5 nm to 2000 nm. The process includes re-firing lithium titanate under controlled conditions so that crystallites of the desired particle size are grown. The lithium titanate may be derived from any suitable source. A suitable source of lithium titanate can be from a process that includes evaporation of a blend that contains lithium and titanium to form a mixture containing lithium and titanium compounds that are subsequently calcined to form lithium titanate. The blend of titanium and lithium may be derived from a variety of titanium and lithium precursor materials.

A process is provided for making nano-sized or sub-micron sized oxides of lithium and a transition metal. The desired size is generally in the range 10 nm to 1000 nm and preferably in the range 10 nm to 100 nm. The particles have a narrow size distribution. The process includes milling and re-firing under controlled conditions so that crystallites of the desired particle size are grown.

A hydrometallurgical process is provided for producing pigment grade TiO from titanium containing solutions. Generally, the solution is an aqueous solution. The process includes hydrolyzing the solution via complete evaporation in well-controlled conditions of temperature to form titanium oxide of well-defined characteristics. The hydrolyzing can be achieved by spray hydrolysis in a spray dryer. After hydrolyzing, the titanium oxide is calcined to transform the titanium oxide to the desired form of titanium dioxide. The titanium dioxide can be either anatase or rutile. Following calcination, the titanium dioxide is milled to provide the desired particle size distribution and then finished.

Processing aqueous titanium solutions to titanium dioxide pigment

A hydrometallurgical process is provided for producing ultrafine or nano-sized titanium dioxide from titanium containing solutions, particularly titanium chloride solutions. The process is conducted by total evaporation of the solution, above the boiling point of the solution and below the temperature where there is significant crystal growth. Chemical control additives may be added to control particle size. Nano-sized elemental particles are formed after calcination. The titanium dioxide can be either anatase or rutile. Following calcination, the titanium dioxide is milled to liberate the elemental particles and provide a high quality nano-sized TiO with a narrow particle size distribution.
