What is nano-silicon powder? Nano-siliconwith a particle diameter of a narrow particle range. Nano-silicon powder is a new generation of photoelectric semiconductor material, a wide gap energy semiconductor, and a high-power light source material. Nano-silicon particles have a large specific surface, are colorless and transparent, have low viscosity, have strong permeability, and have good dispersion. Nano-silicon dioxide particles are of nanometer level, and their particle size is less than the length of a visible light wave.
Application of nano-silicon powder waterproof agent 1. Waterproof concrete construction: nano-silicon waterproof agent can be added with 45 times of water (volume ratio) to prepare concrete directly. The construction method is the same as that of ordinary concrete/after construction, the cement curing agent produced by our company shall be maintained or sprayed normally 2. Leakage maintenance construction: the original base course must be chiseled into a pitted surface when smooth. After cleaning the floating ash, make a plain mortar binding layer and plaster the waterproof mortar layer. The leaking part must be sealed first. The internal and external corners should be made into rounded corners and compacted. The stubble should be sloped (the width of the stubble should be 100~150mm). The stubble should be painted with plain mortar before plastering the waterproof mortar layer.
Preparation of nano-silicon powder Laser-induced chemical vapor deposition method uses laser-induced chemical vapor deposition as the input energy source. With laser photolysis, gas molecules or atoms are activated instantly to complete nucleation quickly, but there is no time to grow and form nanoscale particles. Irradiate SiH4 gas with a specific wavelength of the high-energy laser to induce SiH4 dissociation, and then the silicon source is re-nucleated and grown; nano-silicon particles of different sizes can be obtained by controlling the relevant reaction conditions. The LICVD method can achieve rapid temperature rise and cooling so that the nano-silicon particles can not grow in time, and the nano-silicon particles of very small size (below 10nm) can be obtained. The LICVD method has the characteristics of a high concentration of laser energy, large temperature gradient, etc... It is easy to prepare amorphous and crystalline nanoparticles of less than 10nm, and the particle size distribution is uniform, pollution-free, and non-binding. It is mainly applied to Si, Si3N4, The synthesis of SiC, and some metal oxide nanoparticles. In recent years, many studies have been carried out on LICVD. Still, there is no definite conclusion on a large number of elementary reactions in the reaction, the establishment of chemical equilibrium relations, and the internal energy state of molecules. LICVD does not need the high reaction temperature requirements of ordinary chemical vapor deposition and is a promising new technology for synthesizing nanomaterials. However, its application is still concentrated on small-batch production. The realization of large-scale synthesis of nanoparticles by LICVD is an important direction of future research.
Price of nano-silicon powder Nano-silicon powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of nano-silicon powder. A large amount of large amount will be lower. The price of nano-silicon powder can be found on our company's official website.
