    Zirconium Boride Powder

    Description

    A light grey metallic powder, chemically attacked very little by cold HCl, more rapidly by HNO3, and is dissolved by aqua regia. It reacts with H2SO4 and is readily attacked by fused alkali hydroxides, carbonates and disulfides. Produced by various processes.
    ZrB2, a hard, toxic, gray powder that melts at 3000°C;  It is also known as zirconium diboride.
