6. Zirconium - Wikipedia

   en.wikipedia.org/wiki/Zirconium

   The most common oxide is zirconium dioxide, ZrO 2, also known as zirconia. This clear to white-coloured solid has exceptional fracture toughness (for a ceramic) and chemical resistance, especially in its cubic form. [37] These properties make zirconia useful as a thermal barrier coating, [38] although it is also a common diamond substitute. [37]
