Description
Technical field
The present invention relates to thermo electric material, especially the Nano metal powder thermo electric material.
Background technology
Along with development of technology and growth in the living standard, electric heating and fuel gas product are widely used.The drawback that fuel gas product exists is to produce carbon monoxide easily because of fuel gas buring is insufficient, if carbon monoxide can not in time be drained, just may cause security incident, so the electric heating product becomes first-selection gradually.Existing electric heating material mainly is metallic resistance silk, carbon fiber, carbon-point etc., and these electric heating materials need machine-shaping, and have shortcomings such as electric conversion rate is low.Nanometer powder is called ultra micro powder or superfine powder again, refers generally to powder or the particle of granularity below 100 nanometers, is a kind of solid particulate materials of the states of matter that mediates between atom, molecule and macro object.Be useful on: high density magnetic recording material, wave-absorbing and camouflage material, magnetic fluid material, radiation proof material, monocrystalline silicon and precision optics polishing material, microchip heat conduction substrate and wiring material, microelectronic packaging material, photoelectron material, advanced person's battery electrode material, solar cell material, effective catalyst, high active combustion agent, senser, high tenacity ceramic material, human body repair materials, anticancer preparation etc.But as the research of thermo electric material seldom to nanometer powder.
