Mesoporous silica sphere is conducive to efficient laser output, or has a wide bandwidth high gain optical amplification, erbium-doped laser can become a new type of optical amplifier or matrix material. High purity spherical silica with conventional SiO2 do not have the special optical properties, it has a strong UV absorption, infrared reflectance. The spectrophotometer tests show that its UV absorption wavelength of 400mn rate of less than 70%, less than 400nm wavelength infrared light reflection rate of 70% or more. Spherical nano-silica as a versatile active ingredient, can be tailored for different industries. Xinlei spherical nano-silica powder will make the most of our clients greatly benefit from, with many targeted silica products, but also according to customer's need to provide unique and innovative products and provide technical services.
