N2 - On traditional Japanese stoneware called "Bizen", we found that ε-Fe2O3 crystallizes epitaxially on needle-like mullite crystals. This interesting reaction occurred when a pellet of Bizen clay powder was heated with rice straw to 1250°C in a stream of N2 containing 1∼2 vol% of O2. It is known that mullite forms from the clay on heating and that the rice straw provides potassium to induce partial melting in the pellet surface. The ε-Fe2O3-on- mullite particles formed in this molten region, changing their morphology and the relative ε-Fe2O3-to-mullite orientation with oxygen partial pressure. This discovery suggests morphological controllability of ε-Fe2O3 as a function of oxygen partial pressure.
