Boron suboxide (chemical formula B6O) is a solid compound with a structure built of eight icosahedra at the apexes of the rhombohedral unit cell. Each icosahedron is composed of twelve boron atoms. Two oxygen atoms are located in the interstices along the [111] rhombohedral direction. Due to its short interatomic bond lengths and strongly covalent character, B6O displays a range of outstanding physical and chemical properties such as great hardness (close to that of rhenium diboride and boron nitride), low mass density, high thermal conductivity, high chemical inertness, and excellent wear resistance.

  • 低氧化硼 (化学式 B6O) 是一种固体化合物。每一个正二十面体由十二个硼原子而成。两个氧原子沿[111]菱面体方向位于空隙中。由于B6O的原子间键合长度短且具有很强的共价特性,因此显示出一系列出色的物理和化学特性,例如高硬度(接近二硼化铼和氮化硼),低质量密度,高导热率,高化学惰性和出色的耐磨性。 (zh)

  • Le suboxyde de bore est un composé chimique de formule B6O. Il se présente comme un solide cristallisé dans le système trigonal avec le groupe d'espace R3m (no 166) ou dans le système orthorhombique avec le groupe d'espace Cmcm (no 63), selon deux polymorphes du B6O notés respectivement α et β. Ces structures sont formées de huit icosaèdres aux sommets d'une maille élémentaire rhomboédrique. Chaque icosaèdre est constitué de 12 atomes de bore. Deux atomes d'oxygène se placent dans les interstices le long de la direction rhomboédrique [111]. En raison de ses liaisons chimiques courtes et fortement covalentes, ce matériau présente des propriétés physiques et chimiques remarquables, notamment une dureté Vickers de 45 GPa mesurée sur des monocristaux, proche de celle du nitrure de bore BN cubi (fr)
  • Il subossido di boro (formula chimica B6O) è un composto solido con una struttura costituita da otto icosaedri agli apici di una cella unitaria romboedrica; ogni icosaedro è composto da dodici atomi di boro. Due atomi di ossigeno si trovano negli interstizi lungo la direzione romboedrica (111). A causa delle sue brevi lunghezze di legame interatomiche e del carattere fortemente covalente, il subossido di boro mostra una gamma di proprietà fisiche e chimiche eccezionali come grande durezza (vicina a quella del diboruro di renio e del nitruro di boro), bassa densità di massa, elevata conduttività termica, elevata inerzia chimica, ed eccellente resistenza all'usura.
