Coating Material 99.99% Purity Sio2
The 99.99% purity silicon dioxide (SiO₂) crystal pillar from Shandong Longtaili Science And Technology Co., Ltd. is a high-purity evaporation source used in thin-film optical coatings for lenses, filters, and display panels. It is supplied in cylindrical pillar form, typically 2 mm in diameter and 4 mm in length, with a density of 2.2 g/cm³ and a refractive index of 1.45 to 1.46 at 550 nm. The material is colorless and transparent, with a melting point of 1700°C and a transparency range from 0.2 to 9 micrometers.
This grade of SiO₂ is produced through high-temperature purification processes to eliminate metallic impurities and hydroxyl content, making it suitable for applications requiring low absorption in UV and visible spectra. It meets standard industry requirements for optical coating materials, with particle size controlled to minimize plasma arc instability during e-beam evaporation. The material is packaged in sealed 1 kg bags or cans, and 20 kg cartons for bulk shipments.
Buyers include manufacturers of precision optics, semiconductor equipment, and AR/VR display components in Europe, North America, and Japan. The material is used in multi-layer dielectric stacks for anti-reflection, beam splitters, and high-reflectivity mirrors. MOQ is listed as unlimited, with packaging options of 1 kg or 2 kg per container. Storage requires dry, non-acidic conditions and protection from direct sunlight to prevent surface degradation.

Sourcing Coating Material 99.99% Purity Sio2 from Shandong Longtaili Science And Technology Co.,ltd. - China Import Guide
Before ordering, confirm the material's crystalline phase via XRD data and request a certificate of analysis showing trace metal content. Verify that the packaging is moisture-sealed with desiccant, as SiO₂ can absorb humidity even at 99.99% purity. Request a sample batch for deposition testing before placing bulk orders.
Lead time is typically 10 to 15 days after order confirmation. Incoterms are usually FOB Qingdao, with payment via T/T or L/C. Buyers should confirm if the supplier provides MSDS, transport classification (UN3077), and export documentation for hazardous materials. Even though SiO₂ is non-hazardous, customs may require purity certification for customs clearance.
Perform incoming inspection for color uniformity, absence of surface cracks, and packaging integrity. Use a refractometer to verify refractive index on a small sample. Retain a portion of each batch for future comparison. Ensure the supplier provides batch-specific documentation, as contamination levels can vary between production runs even at 99.99% purity.
