  • Patent number: 9573811
    Abstract: The present invention relates to methods for preparing amorphous aluminum hydroxyphosphate. An aluminum salt and a phosphate solution are co-mixed at a constant ratio in the presence of a buffer. Preferably, an excess of the phosphate solution is used to act as a buffer. Due to the presence of a buffer, the pH is maintained constant during reaction (after initial rapid equilibration) without active adjustment. The methods are particularly applicable for the large scale manufacturing of aluminum phosphate adjuvant. Aluminum phosphate is used as an adjuvant in vaccine formulations, particularly those including a protein or saccharide antigen.

  • Publication number: 20150118395
    Abstract: Metal silicates or phosphates are deposited on a heated substrate by the reaction of vapors of alkoxysilanols or alkylphosphates along with reactive metal amides, alkyls or alkoxides. For example, vapors of tris(tert-butoxy)silanol react with vapors of tetrakis(ethylmethylamido)hafnium to deposit hafnium silicate on surfaces heated to 300° C. The product film has a very uniform stoichiometry throughout the reactor. Similarly, vapors of diisopropylphosphate react with vapors of lithium bis(ethyldimethylsilyl)amide to deposit lithium phosphate films on substrates heated to 250° C. Supplying the vapors in alternating pulses produces these same compositions with a very uniform distribution of thickness and excellent step coverage.

    Abstract: APs are made by binary condensation via base-to-acid or acid-to-base routes. In the base-to-acid route, an aluminum hydroxide slurry is added to phosphoric acid that reacts to produce an aluminum phosphate condensate. In the acid-to-base route, phosphoric acid is added to an aluminum hydroxide slurry that reacts to produce an aluminum phosphate condensate. In an alternative base-to-acid route, an acidic aluminum phosphate is first made by adding phosphoric acid to a first amount of aluminum hydroxide slurry, and such acidic aluminum phosphate is added to a remaining amount of aluminum hydroxide slurry to react and produce an aluminum phosphate condensate. The reactions can be controlled to form an in-situ layered aluminum phosphate. So-formed APs can be amorphous, crystalline, or a combination thereof, and have low oil absorption and surface area, making them particularly useful in such end-use applications as extender pigments in coating compositions, replacing up to 70 wt % of TiO2.

  • Patent number: 8399130
    Abstract: This invention relates generally to electrode materials, electrochemical cells employing such materials, and methods of synthesizing such materials. The electrode materials have a crystal structure with a high ratio of Li to metal M, which is found to improve capacity by enabling the transfer of a greater amount of lithium per metal, and which is also found to improve stability by retaining a sufficient amount of lithium after charging. Furthermore, synthesis techniques are presented which result in improved charge and discharge capacities and reduced particle sizes of the electrode materials.

  • Patent number: 8318118
    Abstract: A process for the treatment of gas phase alkaline chlorides in a combustion plant that is arranged for combustion of solid fuel and which includes a combustion chamber from which a flue-gas flow is directed to pass a heat transfer device. A phosphorous substance is added to the flue-gas flow, separate from the fuel, the substance chosen from a group of substances that form phosphorous oxide at combustion temperatures of approx. 500° C. or above, wherein the phosphorous substance is distributed in the flue-gas at a location upstream of the heat transfer device. The phosphorous substance is added to an amount which results in phosphatising of gas phase alkaline chlorides included in the flue-gas flow before the chlorides reach the heat transfer device. A corresponding combustion plant is disclosed, as well as the use of a phosphorous substance for phosphatising alkaline chloride in gaseous phase in a flue-gas flow.

  • Patent number: 8293004
    Abstract: This study reports in vitro and in vivo properties of fluorapatite (FA)-forming calcium phosphate cements (CPCs). Experimental cements contained from (0 to 3.1) mass % of F, corresponding to presence of FA at levels of approximately (0 to 87) mass %. The crystallinity of the apatitic cement product increased greatly with the FA content. When implanted subcutaneously in rats, the in vivo resorption rate decreased significantly with increasing FA content. The cement with the highest FA content was not resorbed in soft tissue, making it biocompatible and bioinert CPC. These bioinert CPCs are candidates for use in useful applications where slow or no resorption of the implant is required to achieve the desired clinical outcome.
