文摘
- •
Bi2Te3 based wastes were directly selected as raw materials for TE alloys.
- •
Contaminants from cutting fluid and oxides could be effectively removed.
- •
Bulk Bi0.44Sb1.56Te3 with ZT of 1.16 was obtained from Bi2Te3 based wastes.
- •
Different from hydrometallurgy, the recycling method introduced here was green.
- •
Directly recycling Bi2Te3 wastes can lower raw material costs of manufacturers.
