What is nano silicon powder? Nano silicon powderrefers to crystalline silicon particles with a diameter of fewer than 5 nanometers (one billionth of a billion (1G) meters). Nano silicon powder is characterized by high purity, small particle size, uniform distribution, large surface area, high surface activity, and low loose density. The product is non-toxic and tasteless. Nano silicon powder is a new generation of optoelectronic semiconductor materials with a wide gap energy semiconductor and a high-power light source material.
Use of nano silica powder First of all, nano silicon powder is made into nano silicon wire and used as the cathode material of rechargeable lithium batteries, or graphite is coated on the surface of nano silicon powder and used as the cathode material of rechargeable lithium batteries, which increases the capacitance and charge-discharge cycle times of rechargeable lithium battery by more than three times. Second, nano silicon powder is used in high-temperature-resistant coatings and refractory materials. In addition, nano silicon can be used in layers to form silicon nanofilms, which are widely used in solar energy. Finally, nano silicon powder and diamond are mixed under high pressure to create a silicon carbide diamond composite material, which can be used as a cutting tool to replace nano carbon powder or graphite as the anode material, significantly improving the capacity of lithium batteries.
Harm of nano silica powder to human body The most considerable harm of silica fume to the body is silicosis, caused by long-term inhalation of silica (SiO2) dust in large doses. Silica dust enters the respiratory tract and engulfs pulmonary macrophages, releasing active factors that stimulate fibroblasts to synthesize more collagen. Silica dust can also stimulate macrophages to release lysosomal enzymes, destroy the protein coated on the surface of SiO2 and expose damaged cell membranes. It can also start lipid peroxidation, produce free radicals, and damage or even kill macrophages. Dead cells can stimulate adjacent fibroblasts to synthesize collagen. Silica dust is released and swallowed by other macrophages to produce more collagen fibers. As time goes on, silicosis develops.
Price of nano silica powder The chemical and physical properties of different nano silicon powders are other, so the prices of different nano silicon powders will differ. The nano-silica powder with high purity can significantly improve the strength and durability of concrete, reduce the alkali content, and reduce the water demand for use. Generally speaking, the higher the purity of nano silicon powder, the higher the price. The price of nano silica powder can be found on our company's official website.
