Quality guarantee

The quality of the sand is guaranteed based on the results of laboratory tests.

Laboratory tests were carried out using a chemical element analyzer based on X-Ray Fluorescence (XRF) and identified with an X-Ray Diffractometer (XRD).

The Silica content reached 86.71%

The main constituent chemical element is Silicon (Si) which is present in two different dominant compounds, namely Quartz (SiO₂) with a mass fraction of 59.76% and Andesine ((Ca, Na)(Al, Si)₄O₈) reaching 40.24%

X-ray diffraction patterns and identification results of compounds and mass fractions.
