Diamond (Ancient Greek: ἀδάμας; French, German: Diamant; English: Diamond; Russian: Алмаз), a mineral composed of carbon, Love Doll is an allotrope of graphite, one of the five key gemstones, Chemistry and industrial applications as diamond. Diamonds are colorless crystals composed of carbon and are the hardest natural substances known. anime sex doll
chemical properties
Each carbon atom in the crystal forms a covalent bond with four other adjacent carbon atoms in sp3 hybrid orbitals, and each four adjacent carbon atoms form a regular tetrahedron. The crystal type is a diamond structure, so the crystal shape without polishing is often an octahedron. mini sex doll The C-C bond in diamond is very strong, and all valence electrons participate in the formation of covalent bonds. There are no free electrons, so diamond is very hard, non-conductive, and has a melting point of 3815°C. The ignition point of diamond is 720-800℃ in pure oxygen and 850-1,000℃ in air. Industrially, diamond is mainly used to make drilling probes and grinding tools. Diamonds with complete shapes are polished and are called diamonds, which can be used to make high-end jewelry and are very expensive. BBW Sexpuppen
There are several known allotropes of carbon: amorphous carbon, carbon nanofoam, diamond, lonsdaleite, waxstone, polymerized diamond nanorods, cyclocarbon graphene, graphite, and fullerene. Thermodynamically, diamond is less stable than graphite and can spontaneously transform into graphite. However, the speed of this transformation is very slow and can be ignored under normal temperature and pressure, so diamond can exist stably. Japanische Sexpuppen Diamonds formed in nature are generally formed in the high-temperature and high-pressure environment of the earth's interior, and are later brought to the surface by volcanic eruptions and other crustal tectonic movements. Therefore, many diamonds are found near volcanoes. Modern industry can produce diamond under high temperature and pressure, called "synthetic diamond".
