Abstract: Provided is a method for producing a transition-metal-containing silicoaluminophosphate that is highly suitable as a catalyst or an adsorbent and has excellent high-temperature hydrothermal durability and excellent water resistance, that is, excellent durability against water submersion (water-submersion durability), in a simple and efficient manner. A method for producing a transition-metal-containing zeolite, the method comprising a steam treatment step in which a transition-metal-containing zeolite is stirred at 710° C. or more and 890° C. or less in the presence of water vapor, the transition-metal-containing zeolite containing a transition metal in a zeolite having a framework structure including silicon atoms, phosphorus atoms, and aluminium atoms.

Abstract: The system according to an embodiment of the present invention may more appropriately provide recommendation information of contents based on use status of the contents by a plurality of users.

Abstract: An object of the invention is to provide composite graphite particles (C) for nonaqueous-secondary-battery negative electrode, wherein metallic particle (B) capable of alloying with Li are present in inner parts thereof in a large amount. The invention relates to a composite graphite particle (C) for nonaqueous-secondary-battery negative electrode, the composite graphite particle (C) comprising a graphite (A) and a metallic particle (B) capable of alloying with Li, wherein when a section of the composite graphite particle (C) is examined with a scanning electron microscope, a folded structure of the graphite (A) is observed and a presence ratio of the metallic particle (B) in the composite graphite particle (C), as calculated by a specific measuring method, is 0.2 or higher.
