The materials were prepared from a solution containing dehydroxylated kaolinite and alkaline hydroxide pellets dissolved in potassium or sodium silicate.
In a strong alkaline solution, alumino-silicate reactive materials are rapidly dissolved into solution to form free SiO4 and AlO4 tetrahedral units [ H.

These experiments proved the almost complete dissolution of raw materials to create the in-situ inorganic foam.

There has been a growing interest on surface micro/ nano-structuring of semiconductor materials using ultrashort laser pulses.
As the pulse width decreases, melting threshold of materials decreases.
The extraordinary rate of heating and cooling of materials led to fast material removal with minimum thermal effect on the surrounding material.
