WebRecycling silicon from environmentally hazardous diamond wire saw silicon powder waste (DWSSP) and effectively removing boron is still an elusive aim. Here, pressure-less sintering and dynamic-slag treatment were used to recover the powder waste. On the basis of thermodynamic simulation, the slag composition was designed. WebAbstract Improving the effective utilization of diamond wire saw silicon powder (DWSSP) waste is beneficial to increasing the production profit of the photovoltaic (PV) industry. It is also important to reduce the emissions of DWSSP to control environmental pollution.
