Abstract :

The use of alcoholic suspensions of calcium hydroxide nanoparticles as consolidant for natural stone is widely accepted, mainly in Cultural Heritage Conservation. In the present experimental work, two easy synthetic procedures leading to pure Ca(OH)2 nanoparticles in 2- propanol are compared. CaCO3 and Ca(OH)2 were used as starting materials to obtain CaO following two different paths using the same calcinations temperatures. In both cases, CaO was used to obtain suspensions of Ca(OH)2 nanoparticles by addition to 2-propanol while sonicated. The nanoparticles were studied by transmission electron microscopy (TEM) and the stability of suspensions was monitored by Nephelometry (NM). The proposed methods can be implemented in industry because they are fast and easy to scale up. On the other hand, the methods yield pure Ca(OH)2 and avoid the production of by-products, such as NaCl that require additional purification treatments.
