Studies on the Kinetics of Thermal Decomposition of Copper Oxalate Mixed With Silver Oxalate
Abstract: The coprecipitates, Ag2Cu(C2O4)nH2O of varying composition [Ag = (1 and 2)%], have been synthesized and were characterized by means of IR, XRD, and SEM. The decomposition of the prepared oxalates was monitored by differential scanning calorimetry (DSC) and thermogravimetry (TG). The DSC studies reveal that the decompositions of the mixed oxalates were all complex exothermic processes with resemblance to the exothermic reaction of copper oxalate and ranges from 540 to …

Study of Shear Strength Behaviour of Soil With Kaolinite Mixture
Abstract: An experimental testing program was undertaken for evaluating the effect of kaolinite on the strength properties of locally available sand and soil. Strength depends principally upon the content of (1) water, (2) clastic materials and (3) plastic materials. Soils are primarily of two types (1) cohesionless soils in which the strength this produced mainly by the friction of clastic particles against one another, and (2) cohesive soils in which the …
