  • Patent number: 9581030
    Abstract: An environmental protective coating (EPC) for protecting a surface subjected to high temperature environments of more than 3000 degree F. The coating includes a dense platelet lamellar microstructure with a self-sealing, compliant binder material for holding the platelets together. The platelets may be formed from materials that are resistant to high temperatures and impermeable, such as ceramics. The lamellar microstructure creates a tortuous path for oxygen to reach the surface. The binder material may have free internal volume to increase the strain capability between the platelets and absorb increased volume during operation. The binder may be formed from a material that is softer and has a lower temperature capability than the platelets to provide the system with the required compliance and sealing capability. The binder may have sufficient glass content and glass-forming content for initial and long-term sealing purposes.

  • Patent number: 7273521
    Abstract: A new and useful method of simultaneously producing and granulating composite materials for simultaneous internal delivery of high amounts of calcium and phosphate to a subject (person or animal) is provided. Such a method entails the dropwise addition of concentrated phosphoric acid within a specified amount of water into a vessel containing a powdered material of lime and/or calcium carbonate, with the lime and/or calcium carbonate present in an excessive amount of the phosphoric acid, with subsequent, mixing, drying, milling, and sieving to provide the correct target particle size range for the resultant granulated materials. Such specifically produced granulated calcium carbonate/dicalcium phosphate materials exhibit very high available calcium levels, very high available phosphate levels, excellent flow characteristics, and very high capability for compression into tablets. Products including such particularly produced composite materials are also encompassed within this invention.
