This study focuses on the silicate systems in artificial mineralized water, the micro-topography pictures of the silica scales were observed in different solutions (single-silicon solution, Ca2+, Mg2+ and silicon co-existing solution, Ca2+, Mg2+, polyacrylamide(PAM) and silicon co-existing solution, Ca2+, Mg2+, surfactant ORS-41 and silicon co-existing solution, Si4+ solution with Ca2+, Mg2+, PAM and surfactant ORS-41) by the scanning electron microscopy (SEM) at room temperature. The micro-topography was varied in different systems. The results show that silica scale mainly aggregated from spherical particles; silica scale is flaky or lumpy in Si4+ solution with Ca2+, Mg2+, PAM and surfactant ORS-41.
