Among many compounds, metal borides​ have better high-temperature performance than metal carbides. For example, diboride (TiB2) cermets are better suited to high temperature and high erosion conditions than titanium carbide (TiC) and tungsten carbide (WC) cermets. Titanium diboride powder is gray (or gray-black) and ranks sixth among the ten materials with the highest melting point known in the world. Read More »

A transparent metal, indium tin oxide​ (ITO), is an alloy made from a mixture of 90% In₂O₃ and 10% SnO₂. It presents as a clear, tawny film or yellowish-gray mass that is both transparent and electrically conductive. Therefore, it is mainly used for making LIQUID crystal display, flat screen, plasma screen, touch screen, organic light-emitting diode, solar panel, antistatic coating, EMI shielding transparent conduction film, as well as various optical coatings, etc. Read More »
