Definitions
- Ca(OH)2 and Mg(OH)2 nanoparticles were dispersed in alcohol (preferably ethyl alcohol) by means of ultrasonic vibration and approximately 16 hours of magnetic stirring.
- Ca(OH)2 and Mg(OH)2 nanodispersive solution was produced containing nanoparticles sized 400nm on the average and a concentration of 5% (weight/volume).
- the invention (the Ca(OH)2 and Mg(OH)2 nanodispersive solution) must be applied right after the stirring process has ended before precipitation of any nanoparticles in the solution occurs.
- Mg/Ca ratio of the solution is 1, that is, Mg and Ca are in equal amounts. If the solution is kept for a while, Ca(OH)2 nanoparticles, which are larger in comparison to Mg(OH)2 nanoparticles, were found to precipitate, and increase the Mg/Ca ratio of the solution.
