Hi Kaleem

Try Cabot, who have a number of aerogels in their catalogue !

Kaleem Ullah

Cabot in china?? can you please be more specific?

Jos Laurie Campbell

If you are just after SiO2 nanobeads ie. less than 500nm in diameter, you can easily make them using the Stober method. After a couple of attempts you should be able to produce decent quantitiy materials equal or greater in quality to those that can be purchased. I have never found purchased nanoparticles to live up to their claimed size and monodispersity, but times may have changed. TEOS, ammonia, alcohol and water is all you need.

thanks, Jos Laurie Campbell, but I need glass nano-beads , the reason is that it is isotropic.
