Abstract

$Zn_2TiO_4$, using an anatase form of $TiO_2$ on zinc crystalline glaze, was shown as effective nuclear agent. Thus the effects on glaze were studied with synthesized $Zn_2TiO_4$ at low temperature. First, the chromophore elements were employed in synthesized $Zn_2TiO_4$ then add them in the zinc crystalline glaze. Crystal creation and development of color by $Zn_2TiO_4$ addition on the zinc crystalline glaze were more effective. Addition of $Zn_2TiO_4$, which is developed in low range temperature, is effected as zinc crystalline nuclear in the willemite glaze. When 5 wt% of synthesized $Zn_2TiO_4$ was added to the willemite glaze, nuclear creation increases and steadily retains. Therefore addition of respectively doped $Zn_2TiO_4$ with CoO, NiO, and CuO would increase doped effects in the glaze, various color willemite crystal were obtained.

아연결정유약에 Anatase 형 $TiO_2$에 의해 생성되는 $Zn_2TiO_4$가 효과적인 결정 생성제로 나타났다. 이에 저온에서 생성되는 $Zn_2TiO_4$를 인위적으로 합성하여 유약의 미치는 효과를 규명하였다. 첨가 $Zn_2TiO_4$는 저온에서 생성되는 결정으로 아연결정 W의 핵으로 작용하는 것으로 밝혀졌다. 합성된 $Zn_2TiO_4$를 유약에 5 wt% 첨가하면 유약 내에 결정생성이 증가하며 안정적으로 유지된다. 특히, $Zn_2TiO_4$ 합성 시 발색제로 CoO, NiO, CuO를 각각 고용시켜 유약에 첨가하면 발색제의 고용효과가 커져 Willemite 결정의 다양한 발색에 큰 효과를 얻을 수 있다.
