Synthesis of calcium hydroxide for heritage conservation

Abstract

Abstract This research aims to employ nanotechnology and spectroscopy in the field of heritage conservation. In this research nanomaterial (calcium hydroxide) used in conservation of manuscripts, paintings and relics because of their impact on reducing the pH of paper which is the basic reason for cellulosic fiber break. The study done in stages, where calcium hydroxide had prepared by chemical method and analysis it by using atomic force microscopes (AFM),scanning electron microscope (SEM), x-ray diffraction (XRD), infrared spectroscopy (FTIR) as a first stage. In the second phase, initialize and the preparation of samples and study the properties of synthetic and hardness and microscopic study of the state of fiber cellulosic. Third phase includes spraying the mixture of nanoparticles with the solvent (ethanol or brobanol) and then left to dry and studying their properties again, where the study proved the effectiveness of nano scale mixture to reduce the pH to a long-term period. This new style in dealing with manuscripts is clean and inexpensive.
