Boron Analysis in Glass Powder

AppNote XRF1088: ZSX Primus IV using APC and a new synthetic multilayer analyzer RX85


Boron oxide (or boric acid) is an important compound for making glass. It is added to glass to decrease the softening temperature without changing the thermal expansion coefficient or chemical durability for glass. The boron element line, B-Kα, has a very long wavelength, making boron analysis by X-ray fluorescence (XRF) spectrometry difficult. Using a high power X-ray tube and an excellent synthetic multilayer analyzer has achieved excellent analysis results of boron oxide (B₂O₃) in glass by XRF. This Application Note demonstrates quantitative analysis results of B₂O₃
