By directly reacting high-purity silicon powder with alcohols under the action of a special catalyst, electronic-grade silicic acid esters can be efficiently synthesized. This process has an atomic economy close to 100%, and the by-product hydrogen can be recycled in a closed loop, achieving green and low-carbon manufacturing. The product purity exceeds 99.999%, and the key metal impurities are below the ppb level. It perfectly matches advanced applications such as semiconductor CVD coating, optical fiber preform rods, and high-purity silica sol. The silicon powder method for electronic-grade silicic acid esters provides core precursor materials for the microelectronics and optoelectronics industries.

Ultra-high purity silica sol is manufactured from ultra-high purity alkoxysilane via a sol-gel process, achieving purity levels up to 99.9999%. Thanks to proprietary silica nanoparticle morphology control technology, our company can precisely regulate particle size, morphology, and degree of association. The product demonstrates exceptional batch-to-batch consistency and finds applications in nanocomposites, various coating materials, inkjet printing paper, and functional resins.

High-purity organic silica sol is manufactured from high-purity silica sol through proprietary process technology, enabling stable dispersion of silica colloidal particles in diverse organic solvents. This product finds applications in insulating varnishes, optical films, coatings, resins, 3D printing, among others.

High-purity silica nanopowder is a nano-silica powder prepared via the sol-gel method and subjected to specialized surface treatment. It features a narrower particle size distribution, superior flowability, and excellent dispersibility, with good compatibility across various resins and organic solvents. This product can be used in printing materials, as a filler for optical films, for encapsulating ICs and LEDs, as an additive in modified resins, and in applications such as coatings, cosmetics, and the production of silicone sol, among others.

Ultra high purity quartz sand refers to quartz sand with a SiO2 content of over 99.999%, which has advantages such as high strength, high purity, strong corrosion resistance, and good chemical stability.
