Introduction Static recrystallisation kinetics of low carbon steel plates containing Nb are important as the final plate grain structure, which influences the mechanical properties, is dependent on the degree of recrystallisation [1-2].

Introduction Due to their distinctive energy conversion functions, lead zirconate titanate (PZT) - based ceramics with a ABO3 perovskite structure have been extensively studied during the last few decades as materials for sensors, transducers and capacitors [1,2].
According to the sonochemistry [27,28], ultrasound causes high-energy chemistry and has increased the reactivity of particles, therefore, there were chemical reactions when the sol of sample A was atomized by ultrasonic atomization.

Thus, the simple notion of SILD chemistry is based on the following: (1) processes of hydroxylation of growing layer, (2) proton-metal cation exchange between hydroxylated layer and water solution, and (3) additional oxidizing by hydrogen peroxide resulted in higher oxidation state of chemisorbed metal ion with forming poor-soluble hydroxide.
Taking into account the deposition peculiarities in porous structures one can expect that SILD technology would be effective also for surface functionalizing of porous Si.
