  • Patent number: 8889027
    Abstract: A nanocomposite thermoelectric conversion material composed of a Bi2(Te1-xSex)3 thermoelectric conversion material (where 0?x<1) as a matrix in which ceramic phonon scattering particles are dispersed. The nanocomposite thermoelectric conversion material produced by adjusting a first aqueous solution of a Bi complex to a higher pH value than an isoelectric point of phonon scattering particles, adding phonon scattering particles not modified on their surface to the pH adjusted first aqueous solution, and mixing the first aqueous solution to which phonon scattering particles have been added and a second aqueous solution including at least the former of Te anions and Se anions.

  • Publication number: 20130240775
    Abstract: A method of producing a nanocomposite thermoelectric conversion material which has a high thermoelectric conversion performance without modifying the surface of the phonon scattering particles and thereby preventing the conventional defects due to an organic phase derived from a modifier. The method produces a nanocomposite thermoelectric conversion material comprised of a Bi2(Te1-x,Sex)3 thermoelectric conversion material (where 0?x<1) as a matrix in which ceramic phonon scattering particles are dispersed, characterized by including a step of adjusting a first aqueous solution of a Bi complex to a higher pH value than an isoelectric point of phonon scattering particles, a step of adding phonon scattering particles not modified on their surface to the pH adjusted first aqueous solution, and a step of mixing the first aqueous solution to which phonon scattering particles have been added and a second aqueous solution including at least the former of Te anions and Se anions.
