N-type strontium lead lanthanum titanate thermoelectric material and preparation method thereof |
| abstract |
The present application relates to the field of material science, and provides an N-type strontium lead lanthanum titanate thermoelectric material and a preparation method thereof. The general chemical formula of the thermoelectric material is Pb 0.94-x Sr x La 0.06 TiO 3 , x is the actual composition of the doping element Sr, and the range is 0≤x≤0.6. The present application adopts the method of ball milling and spark plasma sintering to prepare bulk samples, and the relationship between the linear thermal expansion coefficient and the lattice thermal conductivity is inversely proportional to the prepared Pb 0.94‑x Sr x La 0.06 TiO 3 . The method of the present application is simple to operate, can be applied to other thermoelectric materials, and provides a new solution for finding thermoelectric materials with low thermal conductivity. |
