Abstract
Pure silica gel samples of various pH were prepared using sodium metasilicate and ortho phpsphoric acid. The prepared well set gel samples were characterized by powder XRD, FTIR, UV and EDAX. Amorphous nature of silica gel sample was cofirmed by powder XRD spectrum. The gel was subjected to EDAX to analyze the elemental and atomic percentage of the elements present in the sample. The presence of various functional groups in the grown crystals was identified by performing FTIR studies. The UV absorption study reveals the transparency of the silica gel in the entire visible region.
