Overview
Description

Silica sol is a dispersion of nano-silica in water or non-aqueous solution. Ordinary silica sol has a large impurity content and is limited to traditional industrial fields. The high-purity electronic-grade silica solution produced by the sol-gel method has a purity higher than 99%, which can meet the requirements of the semiconductor, precision polishing and solar energy industries. Its particle morphology, concentration, dispersion medium, PH, etc. can be adjusted according to requirements.

Features

·Low metal content
·Highly uniform distribution
·Good stability

Application

It can be widely used in chip CMP, solar wafer crucible, aerogel, metal/ceramic processing, ink, coating, textile, battery, biomedicine and other fields as a material for bonding, filling, coating, polishing, etc.
