In this work, pure La10(SiO4)6O3 and La9.33(SiO4)6O2 have been prepared by the sol-gel process. The conductivity of these materials was also investigated. Access through your organization Check access to the full text by signing in through your organization. Access through your ...
(2) nucleation and growth of the particles due to condensation, (3) addition of a suitable substance, which results in gelling, and (4) a final step in which the material is aged, dried, and densified to get the final sol-gel. The sol-gel process is most preferred foroxidesand oxide...
A process for preparing a sol gel coating composition is also described, the process comprising the steps of: hydrolysing an organosilane in the presence of a catalyst; chelating an organometallic precursor; mixing the hydrolysed silane and the chelated organometallic precursor; and hydrolysing the ...
