68% of the manufacturing costs of solar cell wafer can be attributed to the slurry. The recycling of slurries is mandatory for reducing the costs of manufacturing wafering production, and the disposal of industrial waste, as well as for cutting down pollution levels. Slurries are currently being recycled using the centrifuge(decanter) method. However, this method is less than optimal as it does not completely remove the fine particles, leading to low quality. Also, be cause of the incomplete separation from the oil, it causes the impurities in the dried slurries. This study aims to develope a new recycling technology that overcomes the flaws of the centrifuge by utilizing chemicals. It will provide a total solution to the crucial process of recycling slurries in the making of solar cell wafer, by increasing the efficiency and renewable rate.

In recent years, while the importance of thermal management has been emphasized due to smaller electronic products, various materials have been used as heat sink. In this study, porous ceramic heat sink was developed with SiC, successfully separated from the slurry of SiC occurring in solar energy materials industry and the thermal performance of porous SiC heat sink has been compared with those of aluminum heat sink and pure SiC heat sink through experiment. From the experimental results, it was verified that porous recycled SiC heat sink has better thermal performance than aluminum heat sink since its micropores increase the heat transfer area. In addition, the effect of the micropores on thermal performance has been quantified by increasing convective heat transfer coefficient with numerical analysis.
