Abstract
The influence of x–ray radiation on samples of binder (Li₂CO₃, H₃BO₃, Na₂B₄O₇ · 10H₂O) was examined. The components were ground and placed as thin film on the Mylar foil and exposed to beam of primary x–ray on semi – automatic x–ray spectrometer (Au – anode, 20 mA/ 45 KV) successively for period 1 to 8 hours. Comparative results were observed for x–ray diffraction analysis, scanning electron microscope analysis and sieve analysis.

Keywords: Radiation effect, briquetting conditions, structural changes
