초록
아연결정유약에 Anatase 형 TiO2에 의해 생성되는 Zn2TiO4가 효과적인 결정 생성제로 나타났다. 이에 저온에서생성되는 Zn2TiO4를 인위적으로 합성하여 유약의 미치는 효과를 규명하였다. 첨가 Zn2TiO4는 저온에서 생성되는 결정으로아연결정 W의 핵으로 작용하는 것으로 밝혀졌다. 합성된 Zn2TiO4를 유약에 5 wt% 첨가하면 유약 내에 결정생성이 증가하며 안정적으로 유지된다. 특히, Zn2TiO4 합성 시 발색제로 CoO, NiO, CuO를 각각 고용시켜 유약에 첨가하면 발색제의 고용효과가 커져 Willemite 결정의 다양한 발색에 큰 효과를 얻을 수 있다.
Abstract
Zn2TiO4, using an anatase form of TiO2 on zinc crystalline glaze, was shown as effective nuclear agent. Thus theeffects on glaze were studied with synthesized Zn2TiO4 at low temperature. First, the chromophore elements were employedin synthesized Zn2TiO4 then add them in the zinc crystalline glaze. Crystal creation and development of color by Zn2TiO4addition on the zinc crystalline glaze were more effective. Addition of Zn2TiO4, which is developed in low rangetemperature, is effected as zinc crystalline nuclear in the willemite glaze. When 5 wt% of synthesized Zn2TiO4 was addedto the willemite glaze, nuclear creation increases and steadily retains. Therefore addition of respectively doped Zn2TiO4 withCoO, NiO, and CuO would increase doped effects in the glaze, various color willemite crystal were obtained.
