The structure of magnesium diboride (MgB2) is a hexagonal system with a layer of magnesium atoms between the two layers of boron atoms. Studies have shown that the superconductivity of magnesium diboride is derived from the boron atomic layer. Scientists

Transition metal lanthanum boride (TaB) has potential application value due to its good chemical stability and corrosion resistance, excellent thermal conductivity, electrical conductivity and high hardness. It is suitable for high temperature and wear resistance. It is oxidized and is
