论文摘要
在第一个原理中,来自结构,机械和热动力学属性的两个新的假设锆(ZRB2)多晶型物:(HP6-P63/MMC太空组,第194号)和(OP6-PMMN空间组,第59号),第59号)。与已知阶段(HP3-P6/MMM空间组,第191号)相反,并非易碎。当用锆掺杂金属硼化物时,对这些新阶段的知识可能非常有用。
Two new hypothetical zirconium diboride (ZrB2) polymorphs: (hP6-P63/mmc space group, no.194) and (oP6-Pmmn-space group, no.59), were thoroughly studied under the first-principles density functional theory calculations from the structural, mechanical and thermodynamic properties point of view. As opposed to the known phase (hP3-P6/mmm-space group, no.191) are not brittle. Knowledge about these new phases can be very useful when doping metal borides with zirconium.
