  • Sapphire
    Sapphire is a gemstone variety of the mineral corundum, an aluminium oxide (α-Al2O3).
  • Graphene
    Graphene (/ˈɡræf.iːn/) is an allotrope of carbon in the form of a two-dimensional, atomic-scale, honey-comb lattice in which one atom forms each vertex.
  • Corundum
    Corundum is a crystalline form of aluminium oxide (Al2O3) typically containing traces of iron, titanium, vanadium and chromium.
  • Niobium carbide
    Niobium carbide (NbC and Nb2C) is an extremely hard refractory ceramic material, commercially used in tool bits for cutting tools.
  • Zirconium nitride
    Zirconium nitride (ZrN) is an inorganic compound used in a variety of ways due to its properties.
  • Cemented carbide
    Cemented carbide is a hard material used extensively in cutting tools for machining, as well as other industrial applications.
  • Zirconium carbide
    Zirconium carbide (ZrC) is an extremely hard refractory ceramic material, commercially used in tool bits for cutting tools.
  • Chromium carbide
    Chromium carbide is a ceramic compound that exists in several different chemical compositions: Cr3C2, Cr7C3,and Cr23C6.
  • Beryllium carbide
    Beryllium carbide, or Be2C, is a metal carbide.
  • Lonsdaleite
    Lonsdaleite (named in honour of Kathleen Lonsdale), also called hexagonal diamond in reference to the crystal structure, is an allotrope of carbon with a hexagonal lattice.
  • Silicon carbide
    Silicon carbide (SiC), also known as carborundum /kɑːrbəˈrʌndəm/, is a compound of silicon and carbon with chemical formula SiC.
  • Boron carbide
    Boron carbide (chemical formula approximately B4C) is an extremely hard boron–carbon ceramic, and covalent material used in tank armor, bulletproof vests, engine sabotage powders,as well as numerous industrial applications.
  • Titanium carbide
    Titanium carbide, TiC, is an extremely hard (Mohs 9–9.5) refractory ceramic material, similar to tungsten carbide.
  • Vanadium carbide
    Vanadium carbide is the inorganic compound with the formula VC.
  • Tungsten carbide
    Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms.
  • Rhenium diboride
    Rhenium diboride (ReB2) is a synthetic superhard material.
  • Tantalum carbide
    Tantalum carbides form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaCx, where x usually varies between 0.
  • Ruby
    A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide).
  • Iron tetraboride
    Iron tetraboride (FeB4) is a superhard superconductor consisting of iron and boron.
  • Zirconium dioxide
    Zirconium dioxide (ZrO2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium.
  • Yogo sapphire
    Yogo sapphires are a variety of corundum found only in Yogo Gulch, part of the Little Belt Mountains in Judith Basin County, Montana, United States, on land once inhabited by the Piegan Blackfeet people.
  • Boron nitride
    Boron nitride is a heat- and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.
  • Silicon nitride
    Silicon nitride is a chemical compound of the elements silicon and nitrogen, with the formula Si3N4.
  • Titanium nitride
    Titanium nitride (TiN) (sometimes known as tinite) is an extremely hard ceramic material, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
  • Stishovite
    Stishovite is an extremely hard, dense tetragonal form (polymorph) of silicon dioxide.
  • Material properties of diamond
    Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic.
