文摘

Generally: higher ZT after pre-sieving and high-energy ball milling. Fe2.25Co0.75B as additive to DDyFe3CoSb12 shifts ZTmax to lower temperatures. La1.85Sr0.15CuO4 added to n-type (Mm,Sm)yCo4Sb12 enhances ZT and efficiency. Ta0.8Zr0.2B added to p-type DDyFe3CoSb12 enhances ZT and efficiency. Boride additives enhance hardness, elastic moduli and fracture resistance.
