| Abstract Scope |
Clayey materials from three locations of Western Rajasthan (Jheepasni and Gajsinghpura in Jodhpur district, and Raithal, Jalore district) in India have been studied with the aim to optimize local ceramic water filters named G filters. All composites precursor samples of these functional porous ceramics were composed of 50% by volume of sawdust. A 2 mm x 2mm sieve is used to control the sizes of the raw materials. Composites are press formed to 3l frustum shaped greenwares. Air dried for a week, these greenwares are sintered at 750oC for producing ceramic water filters. Mineralogical investigations using XRD revealed traces of MgO and different salts in all the three ceramics. Stress intensity and compressive strength of these ceramics is studied in relation to grain boundary variations with variation in sintering temperatures. The characterization reveals adaptability of distinct clayey materials towards getting effective filtration rates beyond 1l/h from these water filters. |
