چکیده
태양광 폐실리콘 웨이퍼에서 회수한 실리콘과 카본블랙을 활용하여 탄화규소 분말을 제조하였다. 발전시장에서 결정질 실리콘 모듈이 90% 이상을 차지한다. 모듈의 사용기한이 도래함에 따라 환경과 경제적인 측면에서 실리콘을 회수하고 활용하는 기술은 매우 중요하다. 본 연구에서는 폐패널에서 원료로 활용하기 위하여, 순도 95.74% 웨이퍼로부터 정제과정을 거쳐 99.99% 회수하였다. 분말 합성특성을 살펴보기 정제된 분말과 탄소분말을 혼합한 후, Ar 분위기에서 열처리(1,300℃, 1,400℃, 1,500℃)과정을 수행하였다. 분말의 특성을 입도분포, XRD, SEM, ICP, FT-IR 및 Raman 분석기를 사용하여 분석하였다.

متن کاملSynthesis of silicon carbide using concentrated solar energy
Silicon carbide (SiC) has been prepared successfully using concentrated solar energy provided by the IER-UNAM solar furnace. This has led to the development of a low CO2 emissions process for the production of this material via carbothermic reduction of a silica/carbon (SiO2/C) nanocomposite, which has shown a more reactive carbon for formation of composite, being more thermally stable. Silica ...
متن کاملMicrowave synthesis of phase-pure, fine silicon carbide powder
Fine, monophasic silicon carbide powder has been synthesized by direct solid-state reaction of its constituents namely silicon and carbon in a 2.45 GHz microwave field. Optimum parameters for the silicon carbide phase formation have been determined by varying reaction time and reaction temperature. The powders have been characterized for their particle size, surface area, phase composition (X-r...
متن کاملCombustion Synthesis of Silicon Carbide
Combustion synthesis (CS) is an effective technique to produce a wide variety of advanced materials that include powders and net shape products of ceramics, intermetallics, composites and functionally graded materials. This method was discovered in the beginning of 1970's in the former Soviet Union (Merzhanov & Borovinskaya, 1972), and the development of this technique has led to the appearance...
