Zirconium Boride Powder
It is a light grey metallic powder, a tiny bit chemically affected by cold HCl but more rapidly by HNO3, and dissolved by aqua regia. It reacts with H2SO4 and is readily attacked by fused alkali hydroxides, carbonates, and disulfides and produced by various processes.
ZrB2 is a hard, toxic, gray powder that melts at 3000°C. It is also known as zirconium diboride.
Chemical Formula: ZrB2
