碩士 === 國立臺北科技大學 === 資源工程研究所 === 107 === Energy is the fundamental of human development. The demand for the solar industry has increased, and the problem that has arisen which is the large amount of waste generated in the process. The high viscosity of the twin-cutting waste material is currently treated by incineration, which not only increases the cost of waste disposal and raw materials, but also pollutes the environment. Since the cut waste SiC produces nanometer-sized fine particles and a large amount of niobium carbide abrasive particles, it is possible to effectively recycle waste materials and make more valuable use, such as grinding particle re-cutting, which can not only effectively reduce costs and waste but can also reduce a large amount of waste; use replica template method to synthesize SiC porous ceramics by Taguchi Method , and the sintering temperature, PVA ratio and flux type are discussed as the compressive strength and porosity analysis of the test body. In this study, using SiC and other added fluxes make the ceramic slurry, and the PU sponge was impregnated to coat the slurry on the template, and then sintered into a reticulated porous ceramic sample through a high-temperature sintering template. Taguchi analysis showed that 4wt% PVA and 5vol% antifoaming agent were selected as 122.2g SiC, 4wt% sodium carbonate was additionally added as flux, extrusion method, sintering temperature was 1200 °C hold time 5 hours, and the sample was sintered. Obtaining a compressive strength of 20.20 MPa; selecting 5 wt% PVA and 0 vol% defoaming agent as 150 g of SiC, additionally adding 4 wt% kaolin as a flux, extrusion method, sintering temperature of 1300 ° C hold time 3.5 hours, forming a test body sintering was get obtain a porosity of 74%.
