Properties and Microstructures of Sn-Bi-X Lead-Free Solders

The SiC nanoparticles were also incorporated into the Sn-58Bi solder . The shear strength of the Sn-58Bi solder with SiC nanoparticles additions was increased to 95, 85, and 74 MPa during 0, 100, and 400 h for aging, respectively. The growth rates were 9.2%, 7.5%, and 12.1%, respectively.

Thermoelectric and mechanical properties of ZnSb/SiC

Intermetallic compound ZnSb is a promising thermoelectric (TE) material with the advantages of low toxicity, abundance, and low cost; however, the relatively low figure of merit ZT and the brittleness of ZnSb limit its appliions in TE devices. In this study, ZnSb/SiC nanocomposites were synthesized in order to improve both the TE and mechanical properties of ZnSb.

Assessment of Cu, Pb, Zn, and Cd in groundwater in areas

The assessment of the concentration of Cu, Pb, Zn and Cd in groundwater in Enyigba is critical because of presence of numerous Pb – Zn lodes and conditions that are capable of mobilizing the metals into groundwater and pedalogical systems. Groundwater forms one of the major sources of potable water in the area. Analyses of samples of groundwater in the area however reveal that heavy metals

Manganese-silicon interaction and its effect on growth of

In the absence of Si, the optimum Mn level was 0.25 to 0.50 mg/l. One mg/l Mn was toxic and reduced plant growth. The addition of 5 mg/l Si to the nutrient solutions decreased accumulation of Mn, Cu, Fe, and Zn in the plant tissues, and in fact induced Mn deficiency …

Reaction Stoichiometry | Chemistry

The unknown is the mass of SiO 2 required to produce 3.00 kg (3000 g) of SiC. To calculate the mass of SiO 2 required, determine the molar masses of SiO 2 and SiC. Then calculate the nuer of moles of SiC required, and through the mole relation of SiO 2 to SiC, find the mass of SiO 2 required. The conversions required are: [latex]\text{g SiC
