Nalco Water is an industry leader in high-quality, effective colloidal silica abrasives for electronic polishing. In addition to our comprehensive product lines for CMP and prime wafer polishing, we provide colloidal silica for various polishing applications including sapphire substrate and hard disk polishing.
Sodium-Stabilized Colloidal Silica Products
Colloidal Silica for Sapphire Substrate Polishing
Sapphire offers several significant advantages as a substrate (such as stability and optic permeability) for advanced semiconductor and microelectronic devices. However, sapphire substrate can be challenging to process due to its extremely high hardness and low impact strength.
Nalco Water has developed colloidal silica products that provide the quality, consistency, and control appropriate for sapphire substrate polishing.
Colloidal Silica for Hard Disk Polishing
Colloidal silica is an optimal abrasive for hard disk polishing because it helps create an ultra-smooth, defect-free surface. Our electronic polishing RD&E teams work to ensure our colloidal silica products are optimally effective for hard disk drive manufacturing.
