Zirconium carbide (ZrC) is a very tough refractory ceramic material. It is generally processed by sintering. It's the appearance of the grey metallic powder with cubic crystal structure. In a resistance or electric powered arc furnace, boric anhydride (B2O3) is carbothermically diminished at temperatures exceeding 2000°C to supply boron carbide. https://zanderxvwwu.daneblogger.com/33437807/everything-about-titanium-iv-carbonate
