The physical properties of ultrafine silica, silica, also known as silica manufacturers, chemical formula SiO ?. Naturally occurring crystalline silica and amorphous silica two kinds. That is the main component of silica crystalline silica sand because different crystal structures, divided quartz, tridymite and cristobalite three. Pure silica as colorless crystals, large transparent quartz called prismatic crystals. If the crystal containing traces of impurities with different colors, amethyst, citrine and so on. Ordinary quartz sand is fine, there is yellow sand (more iron impurities) and white sand (fewer impurities than the pure). Silica crystal, four valence electrons and four oxygen atoms to silicon atoms forming four covalent bonds, the silicon atom in the center of the regular tetrahedron, four oxygen atoms are located on the four vertices of the regular tetrahedron, SiO ? is the simplest type consisting of crystalline silica is only expressed in the number of atomic ratio of silicon and oxygen. Silica is the atomic crystal. Good quality ultrafine silica Which | Weifang Fuyuan (certified) | ultrafine silica provided by Environmental Science and Technology Co., Ltd. Weifang Fuyuan.
