  • 산업의 발달과 생활수준의 향상으로 생활환경을 쾌적하게 하여 보다 나은 생활환경을 만들에 내는데 관심이 집중되고 있으며, 이와 관련된 의류용 섬유 분야에서는 미생물에 대한 저항성이나 악취, 땀냄새 등을 제거하는 섬유에 대한 관심이 높다. Calcium Hydroxyapatite(Ca$_{10}$(PO$_4$)$_{6}$(OH)$_2$, HAp)는 칼슘 포스페이트계 세라믹으로 우수한 생체친화력과 단백질 흡착능력을 지니고 있어, 골 대체용 재료나 단백질을 분리하는 크래마토그래피, 유전자 담채 둥에 이용된다.[1] (중략)략)

  • Since the monolithic ceramic substrate was introduced for automotive catalytic converters, the durability of the substrate has been a continuing requirement to reduce the emission gas of vehicle. The substrate can occupy a volume as small as 82 $cm^3$ and as large as 8200 $cm^3$ to provide the required substrate for catalytic activity. The long-term durability varies with the size of the substrate from manufacture's point of view. Therefore This study presents that the response surface model using central composite design can explain size effect on the modulus of rupture in a cordierite ceramic monolithic substrate.
