High Purity Silica Sol For Sapphire Polishing
Hubei Jinwei Group produces high purity silica sol under the model FW-GD4030, a sodium-stabilized colloidal silica dispersion containing 30% SiO2 and 0.5% Na2O. The slurry is formulated with a controlled pH of 9.0 to 10.5, making it ideal for chemical-mechanical polishing of sapphire and advanced ceramics. Its low viscosity at 20°C ensures even application and residue-free polishing in precision environments.
This silica sol is designed for semiconductor, LED, and optical component manufacturing, where surface flatness and clarity are critical. The colloidal silica particles, typically in the 40-80nm range, provide consistent abrasion without scratching delicate substrates. Sodium stabilization enhances the slurry’s chemical stability, preventing aggregation during extended polishing cycles.
Industries such as watch glass production, LED wafer processing, and semiconductor fabrication rely on this product for its ability to achieve sub-nanometer surface roughness. Hubei Jinwei Group supplies it in export-ready packaging, but buyers should confirm compatibility with their specific polishing equipment and process parameters.

Sourcing High Purity Silica Sol For Sapphire Polishing from Hubei Jinwei Group - China Import Guide
Before ordering from Hubei Jinwei Group, verify the SiO2 concentration and Na2O content via a certificate of analysis (COA) to ensure consistency with your polishing process. Confirm the pH stability over time, as fluctuations can affect polishing rates. Request a sample for testing on your specific sapphire substrates to validate performance.
Clarify logistics terms such as lead time, which may depend on order volume and production schedules. Hubei Jinwei Group’s location in Wuhan suggests FOB Shanghai or Ningbo as likely Incoterms; confirm whether CIF or DAP options are available to your facility. Payment terms for chemical slurries often include a 30% deposit with the balance due before shipment, but this should be negotiated directly.
For quality checks, measure the particle size distribution using dynamic light scattering (DLS) to confirm it matches the 40-80nm range. Test the slurry’s pH and viscosity upon receipt to ensure they fall within the specified ranges. For semiconductor applications, perform a polishing trial to assess material removal rate and surface roughness. Request an MSDS to ensure compliance with handling and disposal regulations.
