Abstract
Provided are a P-type ZrCoSb-based half-Heusler single crystal alloy and a preparation method thereof. The method for preparing the P-type ZrCoSb-based half-Heusler single crystal alloy includes: subjecting alloy raw materials to smelting under a first protective atmosphere to obtain a half-Heusler polycrystalline alloy ingot, the alloy raw materials corresponding to a chemical composition of the P-type ZrCoSb-based half-Heusler single crystal alloy; and subjecting the half-Heusler polycrystalline alloy ingot to vertical Bridgman directional crystallization under a second protective atmosphere to obtain the P-type ZrCoSb-based half-Heusler single crystal alloy. The P-type ZrCoSb-based half-Heusler single crystal alloy has the chemical composition of ZrCoSbSn, x in the ZrCoSbSnbeing in a range of 0.1≤x≤0.3; and the P-type ZrCoSb-based half-Heusler single crystal alloy has an MgAgAs-type crystal structure.
