| Abstract: | SiO2 optical fiber perform was parent material of communication optical fiber.This paper use TEOS and water as main materials,alcohol as solvent,hydrochloric acid and ammonia water as catalyst,formamide as additive to prepare SiO2 optical perform jel based on SG method,and heated at different temperature（50,60,70,75,80,90℃） to prepare the dry gel.It has discussed different molar ratio of water/TEOS,alcohol/TEOS,hydrochloric acid/ammonia water and pH effecting on preparation of SiO2 gel.Formamide can delay and resist crack form on SiO2 dry gel.XRD analysis showed SiO2 dry gel prepared at different temperature were all amorphous.Infrared spectroscopic analysis showed structural of SiO2 dry gel was silicatetrahedron.SEM analysis：surface cracks increased when heat temperature was above 75℃.Results showed the best heat temperature（gel appeared earliest and least surface cracks appeared on dry gel） was 75℃. |
