  The effect of particle size and the heat treatment on precursor powder and subsequent phase formation of silver tube Bi-2223 wire has been studied. First, we have prepared a series of Bi1.66Pb0.34Sr2Ca2Cu3Oy samples with different sintering temperatures and studied the phase formation in these samples. Second, different particle size distributions were obtained by grinding powders of best for...

Saturated hydraulic conductivity (Ks) is one of the most important soil physical characteristics that plays a major role in the soil hydrological behaviour. It is mainly affected by the soil structure characteristics. Aggregate size distribution is a measure of soil structure formation that can affect Ks. In this study, variations of Ks were investigated in various aggregate size distributions ...
