Zirconium Diboride
Introduction:
Formula: ZrB2, CAS No.：12045-64-6, the crystal structure of ZrB2 is hexagonal crystal system that is similar with metal structure. Due to this, ZrB2 provides excellent conductivity and migration characteristic. Further more, Zr~B ionic bond between boron atom and Zr atom and B-B covalent bonds are so strong that ZrB2 is a high melting point, high hardness and high stability material. At the same time, it also shows better flame retardancy, heat proof, oxidation resistance, chemicals resistance. Its density is 6.085～6.17, melting point is 3,040℃, Rockwell hardness is 88-91 and the compressive strength is 1,555.3 Gpa. It is resistant to the etching of Al, Ca, Mg, Si, Pb and Sn and its resistivity is 16.6×10-5Ω•cm, thermal conductivity is 24.27W/m•K. |
