1. Description
Silica, or silicon dioxide (SiO₂), is one of the most abundant minerals on Earth. It exists in both crystalline (quartz) and amorphous forms. Our silica is sourced from high-purity quartz and offered in lump or fine powder formats. It is used across multiple sectors for its chemical stability, hardness, and functional filler properties.
