| Abstract: | Using water as dispersant agent,Al(OC_(3)H_(7))_(3),Al-chloride and TEOS as raw materials,HCl and HAc as compound accelerating agent,PVA as spinning assistant solvent,the spinnable mullite sol is synthesized by sol-gel method,and the better proportion of reagents,effect of hydrolysis on succeeding heat treatment and the relationship of viscosity and temperature of mullite sol are analyzed,so it may draw necessary lessons from those investigation for preparing the continuous mullite.The various characters of mullite sol are investigated by using DTA-TG,IR,XRD and rotation viscosimeter. |
