*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

태양전지 재료별 분류
Fig. 1-1 재료별 태양전지 분류
1) 실리콘계 태양전지
결정 실리콘 태양전지는 1954년 벨 연구소의 피어슨 등이 발명해 전력용으로 처음 실용화된 태양전지이다. 가장 긴 사용실적을 가진 태양전지이며 주택용 태양광발전 시스템이나 인공위성용 전원 등
iron oxide mixed with a small amount of additional "promoter" material. When the process begins, the hydrogen gas converts the catalyst to pure iron. Gradually, as the iron catalyst is poisoned by carbon and sulfur compounds, it becomes less effective and must be replaced. Nitrogen gas for the synthesis process comes from the atmosphere, while most of the hydrogen needed is extracted from natural
compound
Present in certain processed meats, including bacon,
smoked fish and smoked cheeses and can be formed endo-
genously after consumption of red and processed meat.
4. Heme iron as a promoter of carcinogenesis
Iron is a carcinogenic metal.
It may be more likely to have co-carcinogenic effects.
Heme iron increase cell proliferation in the mucosa.
such a catalyst, in this case the iron in hemoglobin. If
hemoglobin and the luminol mixture come in contact, the iron in the hemoglobin accelerates a
reaction between the hydrogen peroxide and the luminol. In this oxidation reaction, the luminol
loses nitrogen and hydrogen atoms and gains oxygen atoms, resulting in a compound called 3-
aminophthalate.
