Bagasse is a by-product of the extraction process in sugarcane production. In sugar factories, the bagasse is generally used as fuel in boilers for steam power plants and sugar production. The burning process produces abundant bagasse ash containing high levels of silica (SiO2). The end product...
SiO2 and Ta2O5 films for optical applications were deposited by the process. Films prepared at an oxygen pressure of 1–2×10−4 Torr showed good stoichiometry and dense microstructure, which lead to the absence of significant spectral shifts resulting from changes in the temperature and the ...
The SiO2-Ta2O5 binary scales with different Ta2O5 contents were prepared on MoSi2-based ceramics by pre-oxidation. Hot corrosion with Na2SO4 was carried out at 1000 °C for 8 h. The pre-oxidized SiO2-Ta2O5 scale on ceramics with 10 % Ta2O5 has an excellent hot corrosion resistance....
