Microstructure of irradiated binder Li2CO3 in relation briquetse age

Binders are often added to mixture to help form stable briquetse and prevent caking of the sample at the die surface. Model samples from Li2CO3, Kemika Zagreb were used in investigation. The samples were exposed to beam of the X-ray on a semiautomatics Philips, type X-ray spectrometer (Au-anode, 20 mA, 45 KV) for up eight hours and relative intensities of Li2CO3 were measured.Diffraction measurement were performed at room temperature using Philips Diffractometetric system. Scanning electron micrographs of samples were taken by means of a Joel scanning electron microscope. Standard deviation, sigma was determined by Statistics software program.
