抄録

To determine chemical composition and formation of a new calcium ferrite oxychloride which called A pattern found in the previous work, the characterization of calcium ferrite monochloride hydrates obtained at various compounding ratios (6.0/2.0-4.0/2.0) of CaO/FeCl<SUB>3</SUB> and their heat-treated products were carried out by means of various instruments of XRD, FT-IR, TEM and SEM-EDX. Hydrates as starting materials before heat-treating are identified with a mixture of calcium ferrite monochloride hydrate and amorphous iron oxyhydroxide hydrate with partial carbonation by XRD and FT-IR studies. By electron microdiffraction study on the products heated at 600°C and 700°C, respectively, authors find new two orthogonal reciprocal patterns : B and C except A pattern. By supposing these B and C pattern to be orhorhombic symmetry lattice, principal diffraction lines of XRD pattern of heat-treating products are indexed reasonablly as orthorhombic lattice [B pattern : <I>a</I>=1.015 nm, <I>b</I>=1.781 nm and <I>c</I>=0.440nm] and orthorhombic lattice [C pattern : <I>a</I>= 0.740 nm, <I>b</I>=1.704 nm and <I>c</I>=0.510 nm], respectively. Probable chemical compositions of B and C pattern are estimated to be Ca<SUB>1.6</SUB>Fe<SUB>2.0</SUB>Cl<SUB>0.8</SUB>O<SUB>4.2</SUB> and Ca<SUB>1.9</SUB>Fe<SUB>2.0</SUB>Cl<SUB>0.4</SUB>O<SUB>4.7</SUB>, respectively by EDX microanalysis.
