On the other hand sodium silicates are readily available and less costly so I did a brief search fro silica coating techniques using sodium silicate instead of TEOS. Amongst other articles, I found this report:

Can I use CO2 instead?

<div>Let me preface my question with a sincere thanks for making this protocol available. This synthesis has been on my wish list for quite some time as I can see the open up of my investigation opportunities if I manage to get it done right.</div>
