Silicon Preparation
Silicon nanoparticles can be made by a variety of routes, which may be classified roughly as “chemical” or “physical”. Physical routes generally involve high-temperature and/or vacuum deposition techniques and are favored when the object is to produce small quantities of material for physical or electronic applications and we have therefore restricted our discussion of these methods. Chemical routes tend to produce material of less well-defined composition and size (with some exceptions), but often produce rather large amounts of material and may be compatible with the conjugation of biological molecules at the particle surface.
Silicon application:
1.Rechargeable lithium battery anode material
Make the silicon wires used in the negative electrode material in rechargeable lithium batteries, or silicon powder coated graphite used as a negative electrode material in rechargeable lithium battery, the rechargeable lithium battery improved more than three times the capacity and charge-discharge cycle times. Due to the high absorption rate silicon and lithium batteries, and lithium batteries with silicon nano can greatly improve the capacity of the lithium battery (theory can reach 4000mA / h), while taking advantage of the world's advanced technology, silicon powder coated graphite , composed of Si-C composite materials, can effectively reduce the absorption due to the expansion of silicon when lithium ions, and can increase the affinity with the electrolytic solution, and easily dispersed, to improve the cycle performance.
2.Waterproofing agent.
Features: white emulsion, non-toxic, non-irritating odor, no burning, pH value of 12, the density of 1.15 to 1.2. Scope: excellent results for the base surface water impermeability brick, cement, gypsum, lime, paint, asbestos, perlite insulation board.
Effect: to prevent weathering buildings, the cracking and facades cleaning, stain, mildew, moss functions of secretary of defense; reliable quality, durability, acid and alkali, excellent weather resistance, no corrosion of steel, and the use of safety to facilitate construction.
Silicon powder storage
silicon powder storage: Store in a cool, dry location away from heat, sparks and open flame. Do not store with oxidizing agents, halogens or acids.
