This Section of BS 1902-9 describes a method for analysing silica refractories using X-ray fluorescence.
The method is intended for materials containing more than 92 % of silica (SiO2) on the ignited basis. The ranges of content of constituents are given in Table 1 except for those used in glass manufacture which are given in Appendix C.
Appendix C gives modifications to this method which are required where it is to be used for the analysis of silica sands used in glass manufacture.
