Titanium diboride (chemical formula TiB₂) is an extremely hard ceramic compound composed of titanium and boron which has excellent resistance to mechanical erosion. TiB2 is also a reasonable electrical conductor,[1] an unusual property for a ceramic, so it can be used as a cathode material in aluminium smelting and can be shaped by electrical discharge machining.
it is a chemical compound.

Balofloxacin (127294-70-6) is white crystalline. It is also avaiable in multiple packaging.
