Abstract:

The dense zircon film was prepared via Sol-Gel method using zirconium acetate and tetraethoxysilane as raw materials, and silane coupling agent 3-aminopropyltriethoxysilane (APTES) as surface modifying agent, respectively. Influences of APTES on the phase composition, morphology and antioxidation property of the ZrSiO4 film were investigated. The experiment results indicated that the pure and dense zircon film was achieved with addition of 10mol% APTES into ZrSiO4 sol. Once the molar ratio of APTES was beyond 10mol%, the impurity SiO2 was observed, and the viscosity of the ZrSiO4 sol increased significantly at the same time. AFM results showed that the smooth and dense film was obtained with APTES addition. After 102 h oxidation cyclic test at 1300℃, uncoated SiC substrate gained weight of 0.16%, while samples coated with ZrSiO4 thin films only gained weight of 0.08% and 0.03% before and after addition of APTES. In summary, APTES addition is beneficial for the density of ZrSiO4 thin film, resulting in excellent anti-oxidation property.
