## Key specifications to verify | Property | Typical Range | |----------|--------------| | SiO₂ content | 85%–98% | | Bulk density (undensified) | 200–350 kg/m³ | | Bulk density (densified) | 500–700 kg/m³ | | Loss on ignition (LOI) | 1%–6% | | Average particle size | 0.1–0.5 μm | ## Common applications - High-performance concrete for bridges and high-rise buildings - Refractory castables for furnace linings - Oil well cementing in corrosive environments - Rubber and polymer fillers ## What to clarify before inquiry Share the target application, required SiO₂ content range, preferred form, expected monthly volume, and any specific LOI or carbon content limits.
