ASSESSMENT OF THE CHEMICAL AND PHYSICAL PROPERTIES OF SILICA SAND FOR GLASS MAKING
Publication Date : 01/08/2013
The suitability of silica sand deposits of Gada, Muvur, Yazaram and Mugulbu in Adamawa State, Nigeria for commercial glass production wa assessed based on the chemical and physical properties of the silica sand samples collected in the areas. The results obtained were assessed and compared with the standard requirements for glass making. Gada sand has the highest percentage of silica content of 81% and Yazaram sand has the lowest percentage of silica content of 77.6%, but all samples are within the acceptable limits for glass making. The iron oxide content in all the samples was found to be high, with highest value of 1.94% for Mugulbu sand and lowest value of 1.05% for Yazaram sand. However the iron content for all the samples is above 1% thereby limiting the range of applications to coloured and amber glass manufacturing. The physical properties for all the samples weres found to satisfy the standard requirements for glass making.
