Disadvantages of traditional preparation methods of silica

The traditional preparation method of silica has high reaction temperature, high requirements for equipment, large investment and harsh operating conditions.

Silicon dioxide, also known as silicon dioxide, has the chemical formula of SiO_. There are two kinds of crystalline silica and amorphous silica in nature.

Crystalline silica can be divided into Synchrone, tridymite and Shi Ying due to its different crystal structures. Pure time is colorless crystal, and large and transparent prismatic time is called crystal. If the colors of crystals containing trace impurities are different, there are amethyst, tea crystal and ink crystal. Ordinary sand is tiny timely crystals, including yellow sand (with more iron impurities) and white sand (with less impurities and purer). In silicon dioxide crystal, four valence electrons of silicon atoms form four valence bonds with four oxygen atoms, which are located in the center of a regular tetrahedron and four oxygen atoms are located at four corners of the regular tetrahedron. Many of these tetrahedrons are connected by oxygen atoms at the corners, and each oxygen atom has two tetrahedrons, that is, each oxygen atom is combined with two silicon atoms. SiO_ is the simplest composition expression, which only represents the ratio of the atomic number of silicon and oxygen in the silicon dioxide crystal. Silicon dioxide is an atomic crystal.
