Hello ,
You can prepare sol-gel by using ETOH, TEOS and water.
Method
Ratio of chemicals
  ETOH : TEOS: water = 10 :5: 2
Mix  ETOH , ETOS and water and keep them in the sonicator for 30 mins.
Afterward add 2 drops of conc HCl( it will act as catalyst) and leave
for further 30 mins. Sol gel will be prepared.
Thank you,

Subject: [mems-talk] Sol-Gel Silicon oxide

Hi all,

I’m in need to prepare Sol-Gel silicon oxide using
TEOS. And as I do not have a good background in
chemistry, I wish if some body helps me in giving a
complete receipt (or any helpful information) for the
preparation process.
