| titleOfInvention | Bismuth telluride compound material with bismuth telluride ratio of 1/1 and preparation method thereof |
| abstract | The invention relates to a tellurium-bismuth compound material with a tellurium-bismuth ratio of 1/1 and a preparation method thereofPreparing a method; belonging to the technical field of thermoelectric material design and preparation. The molar ratio of tellurium to bismuth in the tellurium-bismuth compound material is 1/1. The preparation method comprises using TeO 2 As Te source, with Bi 2 O 3 Is a Bi source; firstly, proper amount of TeO is added 2 Reacting with sodium hydroxide, PVP and glycol to obtain a standby solution 1; then adding a proper amount of hydrazine hydrate, and reacting at 155-165 ℃ to obtain a standby liquid 2; then adding proper amount of Bi 2 O 3 And adding the mixture into the standby liquid 2 after uniformly mixing sodium hydroxide and ethylene glycol, reacting, cooling, carrying out solid-liquid separation, washing the obtained solid, and drying to obtain the tellurium-bismuth compound material with the tellurium-bismuth ratio of 1/1. The invention obtains the tellurium bismuth compound material with the tellurium bismuth molar ratio of 1/1 for the first time; this provides a necessary condition for widening the application of the tellurium bismuth compound material. Meanwhile, the method provides a base stone for preparing thermoelectric materials with more excellent performance. |
