What is Silicon Dioxide? The chemical formula ofsilicon dioxide is SiO2. Silicon dioxide has two forms, crystalline and amorphous. Silicon Dioxide in nature, such as quartz and quartz sand, is collectively referred to as Silicon Dioxide. Pure quartz is a colorless crystal; large and transparent prismatic quartz crystal is called crystal, purple crystal containing trace impurities is called amethyst; light yellow, golden and brown are called smoke crystal and chalcedony, Agate and jasper are colored quartz crystals containing impurities. Sand is fine quartz grains mixed with impurities. Opal and diatomite are amorphous Silicon Dioxide. Silicon Dioxide is widely used, mainly for making glass, water glass, pottery, enamel, refractory, aerogel felt, ferrosilicon, molding sand, simple silicon, cement, etc. Silicon Dioxide was also used to make glaze and porcelain matrices in ancient times. Common stones are mainly composed of Silicon Dioxide and calcium carbonate.
Uses of Silicon Dioxide Silicon Dioxide can also be used as a lubricant, an excellent flow promoter, mainly as a lubricant anti-sticking agent, and a flow aid. It is especially suitable for the granulation of oils and extracts, and the particles have good fluidity and compressibility. It can also be used as a flow aid in the direct compression of tablets. As a disintegrant, it can greatly improve the particle fluidity, increase the bulk density, increase the hardness of the prepared tablets, and shorten the disintegration time limit, Improve the dissolution rate of drugs. Granules can be used as internal desiccants to enhance the stability of drugs. They can also be used as filter aids, clarifiers, defoamers, suspension aids, and thickeners for liquid preparations.
Preparation of Silicon Dioxide Sol-gel process is a material preparation method developed in the 1960s. Its basic process is to mix the Silicon Dioxide ester and anhydrous ethanol in a certain molar ratio, stir them to form a uniform mixed solution, slowly add a proper amount of deionized water in the stirring state, adjust the pH value of the solution, add a suitable surfactant, stir the solution, and age it at room temperature to produce a gel. The gel is dried in a muffle furnace to obtain the required nano Silicon Dioxide powder. The sol-gel method is expensive in raw materials and takes a long time to prepare.
Price of Silicon Dioxide Silicon Dioxide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Silicon Dioxide. A large amount of large amount will be lower. The price of Silicon Dioxide can be found on our company's official website.
