title: Routine accurate determination of silica in silicate materials by atomic-absorption spectrophotometry and subsequent computation.
abstract: An accurate method for routine determination of silica in silicate materials is proposed. It is based on the decomposition of the silicate materials with LiCO(3)/H(3)BO(3) flux, stabilization of the silica with fluoride, and the use of a suitable calibration, measurement and computation pattern.
