原料硼粉价格是决定MgB2超导材料制备成本高低的主要因素。不同纯度硼粉的价格相差十分悬殊。从降低原料成本的角度出发,MgB2超导材料的制备首选价格低廉的低纯度硼粉。然而,采
The price of raw material boron powder is the main factor that determines the cost of preparing MgB2 superconducting material. Different purity boron powder price difference is very poor. From the perspective of reducing the cost of raw materials, MgB2 superconducting materials preferred low-cost low-purity boron powder. However, mining
