What is silicon dioxide? Silicon Dioxide minerals refer to minerals with the same chemical formula (SiO) but different structures. These minerals are called isomorphs, mainly quartz, cristobalite, and tridymite. These minerals are mainly found in the earth's granite, sandstone, and chert but are almost absent on the moon. The main reason is that the moon has formed a low-silicon and high-aluminum lunar shell in the evolution of chemical composition; high-silicon granitic rocks are extremely rare: the moon lacks a water system and hot water system that can crystallize Silicon Dioxide minerals like the earth in its evolution. Although Silicon Dioxide minerals are extremely rare in lunar rocks, studying the classification and genesis of lunar rocks is of great importance.
Preparation of Silicon Dioxide Microemulsion method: micro lotion refers to a transparent or translucent multiphase homogeneous thermodynamic stability system spontaneously formed by mixing four components, such as oil, water, emulsifier, and cosurfactant (such as alcohol), in proper proportion. It has small particles, uniform size, narrow particle size distribution, high stability, and its micro heterogeneous nature, which can be used to control the properties of synthetic particles at the molecular level to achieve the goal of synthesizing nanoparticles with good particle size uniformity, It has been successfully used to synthesize nanoparticles such as metal nanoparticles, metal halides, carbonates, oxides, and other nanoparticles as well as organic polymer nanoparticles. Triton X-100/n-octanol/cyclohexane/water (or ammonia) is used to form a micro lotion, and tetraethyl orthoSilicon Dioxide is used as the raw material to prepare SiO2 nanoparticles by hydrolysis reaction. The size of nanoparticles prepared by the microemulsion method is easy to control, and the particles obtained are well dispersed. Therefore, the microemulsion method has a broad prospect in preparing ultrafine particles. However, the cost of the microemulsion method is high, and it is difficult to remove organics, which easily pollutes the environment.
Uses of Silicon Dioxide Silicon Dioxide is widely used, mainly for making glass, water glass, pottery, enamel, etc. It is also the raw material for manufacturing optical fiber, important components of the electronic industry, optical instruments, handicrafts, and refractory materials. Silicon Dioxide is an excellent flow accelerator, mainly used as a lubricant, anti-sticking agent, and flow aid. It is especially suitable for granulating oil and extracting drugs. The particles made have good fluidity and compressibility. In manufacturing granules, Silicon Dioxide can be used as an internal desiccant to enhance the stability of drugs. It can also be used as a filter aid, clarifier, defoamer, suspension aid, and thickener for liquid preparations.
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.
