WebApr 12, 2024 · At a critical breakdown voltage of 30 kV, the maximum surface electric field strength of the diamond/epoxy composite is 34.1 kV/mm (Fig. 4 c, Diamond/EP), which is 26.9% lower than that of the alumina/epoxy composite (46.6 kV/mm). Fig. S12 summarizes the variation law of the maximum value of surface electric field strength with voltage. Diamond is extremely strong owing to its crystal structure, known as diamond cubic, in which each carbon atom has four neighbors covalently bonded to it. Bulk cubic boron nitride (c-BN) is nearly as hard as diamond. Diamond reacts with some materials, such as steel, and c-BN wears less when cutting or … See more Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak See more Unlike hardness, which denotes only resistance to scratching, diamond's toughness or tenacity is only fair to good. Toughness relates to the ability to resist breakage from falls or impacts. Because of diamond's perfect and easy cleavage, it is vulnerable to … See more Diamond is a good electrical insulator, having a resistivity of 100 GΩ⋅m to 1 EΩ⋅m (1.0×10 – 1.0×10 Ω⋅m), and is famous for its wide bandgap of 5.47 eV. High carrier mobilities and high electric breakdown field at room temperature are also important … See more Being a form of carbon, diamond oxidizes in air if heated over 700 °C. In absence of oxygen, e.g. in a flow of high-purity argon gas, diamond can be heated up to about 1700 °C. Its surface blackens, but can be recovered by re-polishing.
