·         2nd-grade Silica with high purity 99% grain size 5-8 mm (water purification silica) 

·         3rd-grade silica with a high purity of 98% and a 3–8 mm grain size (for water purification)

·        silica with 97% purity and 3–10 mm grain size (special for waste treatment)

·         silica with a SiO2 content of 95 to 97 %, used in factories and industries to produce cement and silica aggregate in light concrete, light brick, and lime-sand brick.
