Molecular formula (Formula):SiO2 Molecular weight (Weight Molecular):60.08 No.:61790-53-2 CAS diatomite is a kind of silica rock, mainly distributed in China, the United States, Denmark, France, Romania and so on.
Our diatomite reserves of 3.2 tons, long-term reserves of about 2000000000 tons, mainly concentrated in the eastern and northeastern regions, among the larger, more work has been done in Jilin, Zhejiang, Yunnan, Shandong, Sichuan Province, the distribution is wide, but the quality of soil is not concentrated in Jilin, Yunnan Changbai diatomite mining, particularly rich in resources. Most other deposit is 3~4 soil, due to high impurity content, can not directly use of deep processing. The diatomite is composed of amorphous SiO2, and contains a small amount of Fe2O3, CaO, MgO, Al2O3 and organic impurities. Diatomite usually pale yellow or pale gray, soft, porous and light industry often used as insulation materials, filter materials, fillers, abrasive materials, water glass raw materials, decoloring agent of diatomite filter agent, catalyst carrier etc..
Under the microscope, it can be observed that the special porous structure of natural diatomite is the reason of the physical and chemical properties of diatomite. The main component of diatomite as carrier is SiO2. For example, the active component of the industrial vanadium catalyst is V2O5, the catalyst is alkali metal sulfate, and the carrier is the purified diatomite. The experimental results show that SiO2 has a stabilizing effect on the active component, and it increases with the increase of K2O or Na2O content. The activity of the catalyst is also related to the dispersion degree and pore structure of the carrier. After treatment with acid, the content of oxide impurity was decreased, the SiO2 content increased, the specific surface area and Kong Rong also increased, so the carrier effect of refined diatomite was better than that of natural diatomite. Diatomite is generally referred to as after death by single cell algae diatom remains of silicate formation, its essence is the amorphous hydrous SiO2. Diatom in fresh water and salt water can survive, a lot of species, generally can be divided into "central mesh" diatom and "feather" diatom, each one, and there are many "Genus", quite complex. The main component of natural diatomite is SiO2, the quality of the color white, SiO2 content is often more than 70%. The single diatom is colorless and transparent, and the color of diatomite depends on the clay mineral and organic matter. Diatomite is a kind of fossil diatom deposit which is formed by the accumulation period of 1 to 20 thousand years after the death of a single cell plant called diatom. Diatoms are one of the earliest living creatures on the earth. The diatomite is formed from the remains of diatoms from single celled aquatic plants, the unique performance of the diatom is the bone formation of free silicon can absorb water, when the end of life after deposition, diatomite deposit formed under certain geological conditions. It has some unique properties, such as porosity, low density, large surface area, relative incompressibility and chemical stability in distribution and the surface properties of the original soil crushing, sorting, calcination, air classification to miscellaneous processing procedures to change its size. Can be used in paint additives and other industrial requirements.
