Synthesis of Ca(OH)2 nanoparticles by means of ion exchange process
Simple and scalable synthesis process, based on the use of an ion exchange resin, that allows to produce, at room temperature, starting from cheap or renewable reactants, and without necessity of intermediate steps of washing or peptizations procedures, pure and crystalline Ca- and Mg- hydroxide nanoparticles
Ca-hydroxide nanoparticles in hydro-alcoholic suspensions are emerging as effective conservation material for all carbonatic-based substrates and mortars of Cultural Heritage, guaranteeing compatibility, reduced environmental impact and human risk.
Similarly, the development of nanoscale Mg-hydroxide revealed considerable interest in the deacidification of paper (with gallium ink or aluminated) and wood (ancient ships), but also
as antibacterial and flame retardant agent
