Web1 dec. 2002 · Phosphorus-doped silica is also widely used in fiber optics and optoelectronics. Phosphorus incorporation in silica increases its refractive index practically without alteration of dispersion. It follows from [17] that λ0 in phosphorus-doped silica is insignificantly shifted to shorter wavelengths. WebOne further required definition is the silica saturation index (SSI). This is defined as the ratio of the silica concentration in the brine divided by the equilibrium amorphous silica solubility at the conditions prevailing. If SSI >1.0 then silica scaling is possible, if SSI <1.0, then generally, silica scaling will not occur. 3. husqvarna 3120xp bar and chain https://round1creative.com
