According to IOTA's latest technical data, its electronic-grade silica sol features several industry-leading indicators:
-
Ultra-High Purity: SiO₂ purity up to ≥99.999%, with some high-end models reaching 6N grade, and radioactive elements (U, Th) strictly controlled at <0.1ppb, ensuring absolute safety and cleanliness in chip manufacturing.
-
Precise Particle Size & Morphology: Particle size (D50) ranges from 10nm–400nm, spheroidization rate ≥99.0%, with solid particles in perfect spherical shape, effectively improving polishing flatness and stability.
-
Flexible Customization: Solid content adjustable between 5%–30%, pH stable at 8–10, adaptable to CMP slurry formulation needs of different wafer fabs.
Cross-Sector Empowerment: From Chip Polishing to New Aerogel Materials
As a highly dispersed liquid of nano-sized silicon dioxide particles, electronic-grade silica sol's applications are expanding from traditional semiconductor polishing to diverse cutting-edge technologies:
-
Semiconductors & Photovoltaics: As core abrasive in CMP slurries to reduce wafer surface roughness; used in PV silicon ingot crucibles and cell coatings to improve photovoltaic conversion efficiency.
-
Advanced Material Synthesis: A key precursor for aerogel production; combined with IOTA’s organic-inorganic hybrid nanomaterials such as Vinyl POSS (IOTA 66965), novel composites with high temperature resistance, high strength and ultra-low thermal conductivity can be developed.
-
Biomedical & Specialty Coatings: Demonstrating great potential in metal/ceramic treatment, high-end inks, textiles, and biomedical fields.
Accelerated Domestic Substitution, Industry Enters Golden Development Period
For a long time, China's high-end electronic-grade silica sol has heavily relied on imports, with high prices and long lead times. In recent years, domestic enterprises represented by IOTA, leveraging proprietary processes such as "one-step hydrolysis," "microchannel reaction," and "membrane separation purification," have broken overseas monopolies and achieved large-scale mass production. The industry expects the domestic silica sol market to exceed 18 billion RMB by 2026, with a CAGR over 10%. With the adoption of green production processes, domestic high-end silica sol is entering a golden period of high-quality development.
