    Abstract: The present invention provides a carbon fiber that is coated with a composite material. The composite material coating comprises a sulfonated tetrafluoroethylene based ionomer. The present invention also provides a method for producing and using the same. Some aspects of the invention provide a carbon fiber comprising a substantially uniformly coated composite material. In some embodiments, the term "substantially uniformly coated" refers to having a variation of thickness of the coating of about 25% or less, typically about 20% or less, often about 15% or less, more often about 10% or less, and most often about 5% or less throughout at least about 90%, typically at least about 95% and most often at least 98% of the length of the coated carbon fiber.

    Abstract: Provided is a surface-coated barium titanate particulate for use in multilayer ceramic capacitors and for which the grain growth during high-temperature firing has been suppressed. Also provided is a production method for same. Barium titanate particulate obtained by means of a hydrothermal reaction, wherein the coated barium titanate particulate has an average particle diameter of at least 10nm but less than 1000nm, a Ba/Ti ratio of 0.80-1.20 inclusive, a c/a ratio of 1.001-1.010 inclusive, and a coating layer comprising a compound of Mg, Ca, Ba, and Mn and at least one kind of metal selected from the group consisting of rare earth elements is included on the surface thereof. The coated barium titanate particulate according to the present invention is produced by means of a method including: (1) a step for obtaining barium titanate particulate by mixing an aqueous solution containing barium hydroxide and an aqueous solution containing titanium hydroxide at a Ba/Ti ratio of 0.80-1.20 inclusive, and subjecting same to a hydrothermal reaction at a temperature of 200-450°C inclusive, a pressure of 2.0-50MPa inclusive, and for a reaction time of 0.1 minutes-1 hour inclusive; (2) a step for uniformly dispersing the barium titanate particulate in an aqueous solution; and (3) a step for coating the metal compound on the surface of the barium titanate particulate.
