Abstract Metals and their alloys, though having a broad spectrum of applications, cannot fulfill the requirements for the high temperature applications which are being and have been conceived these days. The higher operating temperatures pave the way for further technological advances. In order to sustain temperatures of the order of 1200 °C and higher, ceramic materials come to the fore. While popular ceramics like alumina, silicon carbide, silicon nitride have shown extremely good stability and durability under dry oxidizing conditions, when used in environments found in gas turbine applications, these materials have some limitations. To protect the component from this corrosion, the SiO, has to be protected. With this purpose in mind, Environmental Barrier Coatings have been introduced. These EBCs are primarily corrosion resistant coatings for high temperature applications. For this project, efforts are put together to create a mullite upon SIC EBC substrate utilizing sol–gel creation. For the synthesized mullite characterization has been conducted. It was done through X-ray diffraction (XRD) as well as Scanning Electron Microscopy (SEM). Results of differences in deciding parameters have also been elaborated in detail.
