[China Glass Network] There was once a person who claimed to be engaged in geology: "What is crystal? Crystal is high-grade glass." This person is not geological, can not be verified, it does not matter. The important thing is "crystal is high-grade glass"? The author thinks that "crystal is high-grade glass" is obviously wrong. Anyone with a little knowledge of gems knows that crystal is a natural transparent quartz mineral crystal, while glass is an artificially made amorphous body. Even though the chemical composition of both quartz glass and crystal is both transparent and transparent, it is fundamentally different from the internal structure of the two. Rock crystal is a rare mineral, a kind of gemstone, quartz crystal, belonging to the quartz family in mineralogy. The main chemical component is silica, and the chemical formula is SiO2. Glass is an amorphous inorganic non-metallic material whose main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O.CaO.6SiO2. It can be seen from the above that the chemical composition of the two is completely different. The method of applying X-ray analysis in modern times specifically reveals the internal structure of a large number of crystals. It has been proved that all crystals, regardless of their shape, are regularly arranged in their internal mass points (atoms, ions and molecules). This law is mainly represented by the periodic repetition of the particles, thus forming a so-called lattice structure. Therefore, according to the modern concept, all the particles in the material are regularly arranged, that is, those having a lattice structure are called crystalline. Crystalline is a crystal in a limited part of space. Thus, we can define the crystal as follows: the crystal is a solid with a lattice structure. It can be seen that crystal and glass are two different substances, and there is no scientific basis for thinking that crystal is a high-grade glass.
